SOURCE: Is the video processor board the same thing as the tcon board on a sony lc42d62u? Have sound, no picture. I have replaced backlight inverter boards & main board. Could it be the tcon board?

yes it could be a t-con board but could also be a 12V power supply output failure. The Video processing board, and LCD panel uses 12V

SOURCE: Wondering how to diagnosis a 55 in samsung led tv with solid blue screen. It has sound.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. The fault is related with the video processing section circuit at the main digital board. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

SOURCE: How to test Tcon and other board on Vizio television. When I first connect power logo is bright orange, then slowly dims.

That isn't a timing control board issue, see if you have PSON voltage for starters, if you do then test the various power supply voltages, it could be either the main or power board giving issues, but I would bet on the power supply is bad since the logo comes stays on

About 99% of the boards from shipjimmy are good, unfortunately lI think you have a bad panel and its destroying the tcon board, did you check the fuse on the tcon board?

Hi, We have a 55 inch LG smart TV that has sound but lost picture. It is not under warranty, so we took the back cover off. Backlights are on and working. How do we determine Tcon board vs LED driver?


if the back lights are on then it's not the led driver. it will be the tcon board or cable. try wiggling the cable and connection and see if the pic come on. can also need reseating and that means unscrewing and removing the board and disconnecting the flex cables to the screen. clean the cable connections on the screen cable with a toothbrush and nail varnish remover (cheap stuff) and wipe dry. then refit and see if that works. if not it will be the chip has become unseated and need reflowing or replacing but just as simple to replace.

Good sound no picture at all. No backlights but I can see the menu screen with a flashlight in the dark. Do I change the tcon, main board or the power supply? Thank You


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
