RCA L37WD12 - isolated problem to 1W board

08-01-2012, 11:48 AM

I have isolated the problem to the 5V STDBY on the 1W board. no connection to the scaler board it's 5.3V. connected the scaler board it reads as low as 4.2, however, the voltage very slowly rises.

I connected two 10 watt 50 ohm resistors in parallel for a 25 ohm load. connected to the STDBY 5V and GND and it drops to 4.2V. Is there a CAP kit for this board or do I need to get individual CAPS to replace. Looks like 4 electrolytic CAPS need to be replaced. Any one know what their values may be??

Thanks.... this is a great forum with many graciously helpful people.

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?

by Tynan Dill

I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

Upon bringing it home and plugging it up, it showed a standby light.

I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

The screen seems to blackout and stay black, but with a flashlight I can see the display.

With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Assuming...

TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board

by howardc64
All left and right refers to looking from rear of TV (or looking from front with TV upside down)
- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update

Hi There,

This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

More Details

TV Model - LG OLED77G1PUA

Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...
