I'm in the process of ordering 2 t-con boards, and i found them, but they are from smaller tvs. One is for a 70" sharp, but the replacement is from a 60" with exact same board #, and one is a 42" sanyo, but the replacement is coming from a 40" lg, board # is also identical. Both replacement boards are identical, and have the axact same mounting holes, is there any reason that this wouldn't work? I couldnt find anything pertaining to my issue online, hope someone has some info, or has had to do this before.

Re: t-con board replacement part identification.
Did you go to shopjimmy.com and look up the T-CON board P/N as printed on the barcode to see if there are substitutes for the original one you have?
Blank board (PCB, the white silkscreen for the PCB is printed on the board) can be stuffed to make many version of the PCBA (Printed Circuit Board Assembly) for more than one version of the LCD panel. The P/N on the barcode is the PCBA number that you should go by.Never stop learning

Re: t-con board replacement part identification.

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.

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.

Hello my friends!
I have a question that I think you can answer and help me with!
I have a faulty main board from an led TV. And I found the same part number board and design but is from a 43" TV and I want to use it on a 65". On its stickers , all are the same except the wattage for the LEDs backlight, both state different watts and LED Voltages!
So I presume that the backlight inverter section from the replacement board has lower wattage then the original one, am I right?
My concern is that the board won't draw enough voltage to the bac... -
Hi,
I try to repair this fly-back type PSU, I diagnosed (identifiable) dead N-MOS and fuse, but there are 3 smd resistors on the bottom that burned and became unreadable.
The support in charge of the brand in France managed to get me the schematics from Ecler, but it didn't include the PSU board. After a while they finally told me that the unit was too old so they don't have the PSU board schems.
I can find replacement PSU board online, but only for the Nuo 3 or 4 or 5, and it seems they ar compatible with each other, as I often find boards compatible with these... -
Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....
