hi all this is probably a dumb ass question but im hoping theres going to be a simple answer, yesterday afternoon while watching the tennis my LG lcd tv gave me the blank screen but sound was ok anyways after a bit of a poke around and a big desktop fan i narrowed it down to the t-con board and its fine runs great with a force 10 blowing directly at it. ive ordered a new one but wont be hear till tus/wed,so what ive done is hung a PC fan directly in front of the t-con ,it has two wires red, black.12v pos and negative ,and luckly my PSU had two pins that i needed to run it, empty. So now my question is I COULD DO WITH SLOWING DOWN THE FAN, TO MABE 6V OR 8V PREHAPS. sorry was i shouting becase i didnt know how loud a PC fan could be running at full speed, please is there anything i can just cut the 12v pos cable and solder in to cut the power down a bit and slow the fan a bit any advice would be most help full it only needs to be temp thanks paul

Re: Pc fan on my t-con board to watch the tennis
They sell computer fans with a small pot hanging from a wire off the fan. If you don't mind spending a couple bucks for one. I've got 60mm and 120mm hanging around here somewhere.sigpicThe Sky Is Falling

Re: Pc fan on my t-con board to watch the tennis
maybe what you really need to do is remove the heatsink and replace the paste / pad that obviously isnt doing it's job anymore.Comment

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.

TV Model - LG OLED77G1PUA
Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?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.

This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.
I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match... -
Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic... -
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
