I've got a real stumper here! Working on this unit for a friend who stated that it wouldn't turn on or do anything. When I got the unit all it did was click when you pressed the power button. I read a thread on here that said it must be the tcon board. I ordered a tcon board and the tv started working. It worked for about 3 days and then stopped again. I ordered an SSB board and power board and replaced both of them. Still didn't work. I put the old tcon board back into the tv and it started working again for about a week. I updated the software and it seemed fine for another week. I went to turn it on yesterday and all I get is a bunch of colored vertical lines, green, yellow, white, purple, blue. I called Phillips and they said it might be stuck in a service mode, but couldn't confirm. Please help! Any ideas?

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.

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... -
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.... -

Things about the TV screen
The previous owner was about to throw it out due to the problem. The TV has not had any other maintenance nor has any other defects. There is no physical damage to the TV. The Backlight and audio function perfectly which has lead to think that the mainboard and power supply are in working condition. I already have my own TV so...
