I'm trying to fix a Sanyo model # ***** LCD TV. It's black on half the screen, fine on the other. I watched a cpl You Tube videos...they are saying it's one of the boards inside. Any thoughts. Seems to be a fairly common issue with these TV's.

Customer: replied 10 months ago.
The menu is all visible, however it's also dark on the right side.
Expert:  Anthony_Infotech replied 10 months ago.

Is it like this if you use other inputs like a DVD player for example?

Is it black on top or bottom half or right or left sides?

Customer: replied 10 months ago.
The right side only.
Expert:  Anthony_Infotech replied 10 months ago.

Its either a bad t-con board (most likely)or the LCD panel itself (that would be bad news the catch 22 is their is no way to know you ust have to swap out the t-con and hope it fixes the issue however it has a very good chance do you wish to pursue that?cost of board around $80

That's what I learned on You Tube. Wanted a second/third opinion. One more thing, can I just unplug it to work on it safely?
Expert:  Anthony_Infotech replied 10 months ago.

Its fairly easy to replace

Glad to help, what you need to do is get the back off the set, now you will see a unmistakeable ribbon or multistrand label going from the mainboard (thats the one with all the AV input connectors on)to the t-con usually mounted upper middle of the set and may be covered by a metal shield, you need to carefully get this board out of the set (its about 5 inches by 2 half)and retrieve the partnumber found on the board itself with this partnumber go to www.shopjimmy.com first if they dont have it google the partnumber for suppliers

If you have any problems let me know this is open for 30 days
