HV430QUB-F70 Voltages Data

Here’s a quick-reference for the BOE HV430QUB-F70 (43" UHD) panel’s T-CON power rails—the ranges you should typically see on the HV430QUBF70 T-CON (board number often 44-97717660). Exact set-points vary a little by board revision, but these are the expected ballparks for this BOE QUB-Fxx family.

Supply & logic rails

* VIN / V12 (after T-CON fuse): ~12.0 V (panel spec input). If absent, check the T-CON fuse and main PSU.

* VCC_3V3 / +3.3 V: 3.2–3.4 V (LDO/buck from 12 V).

* VDD_1V2 / VCORE: ~1.1–1.3 V (T-CON SoC core).

* VDDIO / 1.8 V: ~1.7–1.9 V (IO/PMIC logic).

Panel analog/bias rails (from T-CON PMIC/charge pumps)

* AVDD / HAVDD (source-driver analog): typically ~15–18 V (often ~16–17 V on 12 V panels). If totally missing, image will be blank even if backlight is on.

* VGH / Gate-ON: typically +25 to +32 V (often ~28–31 V). If low, you’ll see washed/ghosted image or no picture.

* VGL / Gate-OFF: typically −5 to −10 V (sometimes down to −12 V). If near 0 V, lines smear/freeze; if too negative, flicker/aberrations.

* VCOM: typically ~5–7 V (mid bias for the LC cell, tuned per panel—don’t adjust unless you have the spec/patterns).

* VREF ladder (VREF1…VREF6 or similar): a staircase between ~0 V and AVDD (roughly evenly spaced). These feed the source drivers; if one is missing or off, expect bands/solarization.

Where this comes from / model pointers

* Model & interface: HV430QUB-F70, V-by-One (8-lane), panel supply 12 V (typ.).

* Typical failure anecdotes on sibling QUB-F70 panels (e.g., 65"): loss of AVDD/VGH due to PMIC/enable faults or panel-side shorts. Useful for cross-checking symptoms.

* Board/part cross-refs: HV430QUBF70 / 44-97717660 seen on Philips/Xiaomi 43" sets. (Good to identify test pads silkscreened AVDD/VGH/VGL/VCOM near the PMIC.)

PMIC Mean Power Management I.C 

Quick test flow (practical)

1. 12 V at T-CON fuse? If not, fix PSU/fuse first.

2. 3.3 V present? If missing, upstream DC/DC/LDO issue.

3. AVDD ~16–17 V present? If missing, check PMIC enable from T-CON SoC and look for shorts on AVDD rail at panel COF tabs.

4. VGH ~28–31 V / VGL −6 to −10 V? If VGL is OK but VGH/AVDD are down, suspect PMIC/charge-pump section; if VGH collapses under load, suspect gate-line short on panel side.

5. VCOM ~6 V & VREF ladder steps? If one reference is missing, expect banding/solarization.

UC3842 Working Principles

let’s break this down step-by-step so it’s easy to follow.

We’ll go over UC3842’s working principle, how protection mode works, why the main FET blows, and how to fix/cure the problem.

---

🔌 1. UC3842 Working Principle

The UC3842 is a PWM (Pulse Width Modulation) current-mode controller IC used in SMPS power supplies — common in LCD/LED TVs, adapters, and other electronics.
Its main jobs are:

• Generate PWM signals to drive the main MOSFET/FET.

• Monitor voltage & current to keep the output stable.

• Provide protection against overcurrent and under-voltage.

Key Pins & Roles

Pin	Name	Function
1	COMP	Error amplifier output — adjusts duty cycle.
2	VFB	Voltage feedback from output via optocoupler.
3	ISENSE	Current sense from shunt resistor — protects MOSFET.
4	RT/CT	Timing capacitor & resistor — sets switching frequency.
5	GND	Ground reference.
6	OUTPUT	Drives MOSFET gate.
7	VCC	Power supply for UC3842 (~15V start-up).
8	VREF	Reference voltage (5V) for internal circuits.

How it works in normal mode:

1. Start-up phase – VCC is charged from high-value resistor from mains until ~16V, UC3842 starts switching.

2. PWM generation – UC3842 sends pulses to MOSFET gate to transfer energy through transformer.

3. Feedback control – Output voltage is sensed via optocoupler → adjusts duty cycle.

4. Stable operation – Keeps voltage steady under varying loads.

---

⚠️ 2. How It Goes into Protection Mode

Protection mode triggers mainly through Pin 3 (ISENSE) or low VCC:

• Overcurrent Protection (OCP) – If the current sense voltage exceeds ~1V, UC3842 shuts off the MOSFET for that cycle.

• Under-voltage Lockout (UVLO) – If VCC falls below ~10V, IC stops switching.

• Feedback failure – If optocoupler feedback is missing, output rises → OVP can trigger.

In many SMPS designs, protection mode means:

• IC stops sending PWM pulses.

• Power LED may blink (in TVs).

• Supply keeps trying to restart ("hiccup mode").

---

💥 3. Why the Main FET Blows

The main switching MOSFET (or FET transistor) blows when:

1. No feedback / optocoupler fault → output rises uncontrollably → FET overstressed.

2. Short on secondary side → primary current spikes → FET overheats.

3. Snubber network failure (damaged resistor, diode, or capacitor) → high voltage spikes destroy FET.

4. Dry or leaky primary capacitor → unstable switching → MOSFET avalanche breakdown.

5. Gate drive issues → UC3842 output weak → MOSFET runs in linear region → heat buildup.

---

🛠 4. How to Cure & Prevent This Problem

Step-by-step repair checklist

1. Replace blown MOSFET — use same or higher-rated part.

2. Check UC3842 — often damaged when FET shorts.

3. Test snubber network (across primary winding or FET drain-source) — replace burnt resistors/diodes/caps.

4. Check startup resistor — if open, IC may not start correctly.

5. Replace dried electrolytic capacitors — especially primary filter & VCC capacitor (47µF–100µF, 50V).

6. Check optocoupler & TL431 — ensure proper feedback.

7. Test load — shorted diodes or load on secondary can cause immediate FET failure.

8. Power up with series bulb tester — to avoid instant re-damage during testing.

Preventive design tips

• Use proper snubber circuit to absorb voltage spikes.

• Ensure adequate gate drive from UC3842.

• Keep good quality capacitors in primary side.

• Check transformer insulation — no shorts between windings.

🛠 Sony TV eMMC Recovery & Repair Guide

---

1️⃣ Understanding Sony eMMC in TVs

Sony LCD/LED TVs store their operating system and unique security data inside an eMMC chip (embedded MultiMediaCard).
The data is divided into partitions:

Partition	Purpose	Notes
BOOT1 / BOOT2	Bootloader, minimal firmware	Needed for CPU to start reading OS
User Area (USER)	Main OS, apps, Android system	Can be replaced from donor dump
TA / DRV / SECURE	Security keys, panel config, DRM	Must be kept from original board to avoid losing functions
MISC	Calibration, region settings	Match to panel

---

2️⃣ Why Simple eMMC Swap Fails

• Board-locked keys: BOOT partitions have encryption tied to the CPU.

• Different panel configs: Wrong LVDS/eDP mapping causes no picture.

• Security partitions missing → loss of Netflix, YouTube, or OS boot failure.

---

3️⃣ Recovery Methods

Method A — Safe Clone (Preferred)

When: Original eMMC is healthy enough to read.

Tools: RT809H, EasyJTAG, UFI, or similar.

Steps:

1. Backup Original Chip

   • Connect to original faulty board’s eMMC via ISP pinout.

   • Read FULL dump (BOOT1, BOOT2, USER, EXT_CSD).

   • Save in at least 2 locations.

2. Read Donor Dump

   • Get a full dump from a working identical board.

3. Merge Files

   • Keep SECURE/DRM/TA partitions from the original.

   • Replace SYSTEM/APP partitions from donor.

4. Write Back

   • Program merged dump into original chip or a new eMMC.

---

Method B — Direct Donor Write (Keys Lost)

When: Keys not important (TV used offline or without DRM).

1. Program donor’s full dump to new eMMC.

2. Install on faulty board.

3. Boot and check — Netflix/DRM will not work unless keys restored.

---

Method C — New Blank eMMC + USB Recovery

When: No dumps available but firmware is online.

1. Fit same-size eMMC (Samsung, Hynix, Kingston).

2. Program minimal BOOT1/BOOT2 (from service files).

3. Enter USB Recovery Mode to install full firmware.

Sony USB Recovery Key Combos:

• Android Models:

  • TV OFF → Hold Vol– & Power on TV → Plug in power → Hold until LED blinks amber/white.

• Linux Models:

  • TV OFF → Hold OK button on remote → Power on → Wait for firmware load.

---

4️⃣ eMMC Pinout (Sony Android TV Example)

Most Sony Android TVs use BGA153 or BGA169 packages.
Typical ISP points:

CMD  → Test pad near CPU (label "CMD" or "C")
CLK  → Test pad near CPU (label "CLK" or "CK")
DAT0 → Test pad near CPU (label "D0")
VCC  → 3.3V rail
VCCQ → 1.8V rail
GND  → Ground pad

⚠ Always confirm with board schematic or multimeter before soldering.

---

5️⃣ Partition Map (Sony Android TV Example)

BOOT1        4MB
BOOT2        4MB
RPMB         4MB
system_a     ~1.2GB
system_b     ~1.2GB
userdata     varies
vendor       300–500MB
ta           2–8MB
misc         1MB

💡 Keep ta from original board at all costs.

---

6️⃣ Health Testing Before Programming

Using programmer software:

• Read EXT_CSD — Check life time estimation values.

  • 0x0A = New, 0x0B–0x0C = Medium wear, 0x0D+ = End of life.

• If many bad blocks in boot area → replace eMMC.

---

7️⃣ After Repair

• Run TV → Do factory reset via service menu.

• If panel config is wrong → set correct panel type in Service Menu:

  • Enter service mode: Display + 5 + Vol+ + Power on remote.

8️⃣ Common Problems After eMMC Work

Symptom	Likely Cause	Fix
TV boots but no picture	Wrong panel config	Set correct panel in service menu
TV boots to logo loop	Corrupt system partition	Reflash USER area
Netflix/YouTube error	Lost DRM keys	Restore TA/SECURE partition
TV doesn’t turn on at all	Missing BOOT1/BOOT2 or dead CPU	Reprogram bootloader / check SoC

---

9️⃣ Example Workflow (Technician Short Version)

1. Read original chip fully (save dump).

2. Test eMMC health — replace if bad.

3. Get donor dump for exact model.

4. Merge donor system + original security partitions.

5. Write merged dump to chip.

6. Reinstall chip & test.

7. Final firmware update via USB for stability.

SONY LCD LED TV EMMC PROBLEM

 If you swapped the eMMC from a working Sony LCD TV board to a non-working board and now the eMMC doesn’t work anymore, that means there’s more going on than just “memory chip bad or good.”

Here’s what’s likely happening and how to fix it:

---

1️⃣ Why eMMC Swap Fails Between Boards

Sony mainboards (and most smart TVs) store not only firmware but also:

• Security keys (HDCP keys, DRM licenses, Netflix keys, Google Widevine keys for Android TVs)

• Board-specific calibration data (panel type, LVDS mapping, white balance, backlight curve)

• Bootloader tied to CPU/SOC ID
  → Many Sony boards “lock” firmware to the original SoC, so swapping eMMC to a different board can cause a boot block mismatch and brick it.

---

2️⃣ Common Results After a Bad Swap

• TV stuck on logo or no boot at all.

• TV power LED blinking error codes.

• eMMC unreadable or “protected” in programmer.

• TV shows distorted image (wrong panel data).

---

3️⃣ Correct Method to Repair

Instead of directly swapping the eMMC, you need to clone its contents to the faulty board’s chip or program it with a compatible dump.

Method A — Chip Clone

1. Read the working eMMC fully with an ISP programmer (RT809H, EasyJTAG, UPA, etc.).

2. Save the dump.

3. Write that dump to the faulty board’s original eMMC.

4. Keep the faulty board’s original chip — it contains matching serial keys.

---

Method B — Merge Boot + User Data

Sometimes only the system partitions are needed from the working board.

1. Read the BOOT1, BOOT2, USERDATA partitions from the working board.

2. Merge them with the faulty board’s secure area dump.

3. Write merged dump back to faulty board’s eMMC.

---

Method C — New Blank eMMC + Fresh Software

1. Install a new, same-size eMMC chip.

2. Program it with a full dump (boot + user area) for your exact Sony model and mainboard.

3. If dump not available → use Sony’s USB recovery mode after programming minimal boot sectors.

---

4️⃣ Testing the eMMC

Before blaming the chip:

• Test eMMC with eMMC tester or programmer’s “Check Health” function.

• Check life cycle count — if it’s near end-of-life, it’s safer to replace.

• Look for bad blocks — if many are in critical boot areas, chip is unreliable.

---

5️⃣ Power & Signal Checks

Before and after chip work:

• Ensure eMMC has stable power (1.8V and 3.3V rails).

• Check CLK, CMD, DAT lines for activity with oscilloscope on power-up.

• If no activity, CPU/SOC could be faulty — not the eMMC.

💡 Pro Tip for Sony Android TVs
If you have the original faulty board’s eMMC dump, you can flash only the system image from a good dump but keep the DRM/secure partitions from the original — this keeps Netflix, YouTube, and Android services working.
