    Sanyo CE32LD33-B stuck in "Burn In Mode" (Red-Green-Blue cycling)

    Picked this one up, 32" LCD but very cheap, was stuck in burn in APS mode with cycling test patterns. No response to any buttons. Vestel chassis, 17MB12-3 with 17PW20-1 PSU. To fix, I borrowed an EEPROM from a completely different Vestel board, they are socketed. I hoped set would recognised corrupted EEPROM and attempt to reflash. Well sort of, the TV powered up but with all settings wrong (only 1 HDMI, weird TV mode called "TVMN", etc...) I was able to enter service mode and adjust all settings to the right ones including setting tuner to Thomson so it could receive Freeview broadcasts. After doing this set works perfectly.

    The PSU does have four bulging caps on it, so will have to replace them. The bad caps have also damaged one main board capacitor too, bulging, as it would have been subject to high ripple. I guess it's possible the bad caps corrupted the EEPROM in the first place though set does not currently show any fault symptoms as a result of the bad caps.

        820-02098 stuck at 5volts and cycling at 0,000 amp - 0,030 amp
        by meineiid
        Hi i got an A2442 with liquid damage. The Board is stuck at 5volts and cycling at 0,000 amp - 0,030 amp. Its not in dfu or recovery, i also tried to set it in dfu but doesnt work. With the old Macbooks I could always go through the power sequence, but with the new ones I don't know. I measured these rails PPBUS_AON= 12,35v PP3V8_AON= 3,8v PP1V8_AON= 1,8v PP5V_S2_MAIN= 0v . In logi wiki i says that "most important power rails now are pbus, 3v8 and 5v_S2" but i dont think its the PP5V_S2_MAIN i think something before that.
        Can someone help?...

        Hello everybody, I could use some help on this one... It's got me guessing...
        I took pictures of all the boards and the pin out of the connector on the power supply that goes to the main board... I measured all the pins in relation to chassis ground, here are the result.

        (B13v)1. 12.7 volts cycling (Vamp) 2. 12.7 volts cycling
        (B13v)3. 12.7 volts cycling (PWM5) 4. 1.0 volts cycling
        (OD_LE)5. 2.8 volts cycling (PWM4) 6. 0.9 volts cycling
        (OD_ON)7. 2.8 volts cycling (PWM3) 8. 0.9 volts cycling
        9. ground (PWM2) 10. 0.9 volts cycling...

        Macbook a1707 - 3 ports cycling and 1 stuck on 5v
        by vanromic
        Hello! I'm trying to resuscitate a Macbook that the local tech gave up on. I have the board view and schematic and have the main board out of the case.

        Of the 4 usb-c ports, 3 cycle at 5V - they all go up to about 1.5A, then seem to switch off, back to 5V 0A, up to 1.5A, and off again. The cycle lasts a few seconds - maybe 3s.

        The 4th port doesn't cycle and draws ~0.5A at 5V consistently. It seems it's the port linked to U3100 - it's on that side of the board and is the port closest to the battery and the CD3215C00 chips.

        I've read that the CD3215s are...

        HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
        by ttmi100x
        Greetings everyone,


        I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


        The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
        Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

        Upon closer inspection...

        Insignia NS-43D420NA20 backlight on no display - LCD panel burn failure
        by howardc64
        Eventually discovered a burn mark near lower corner of LCD. Here is a summary
        • Backlight on, no image
        • Disconnect right buffer board (view from front), left side display comes on
        • Masked off pin 7+8 (both ~12,5v on both left and right buffer board) from t-con to right buffer board (view from front) display works but have some lines
        • Buffer board is pretty simple
        Removed the front bezel to examine edge of the glass. Found burn mark on lower right (view from front). Plastic bezel covering the burn mark region shows heat signature on the inside surface facing the LCD panel. Last 2 pics. Bright...
