Back - light problem. 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.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should be troubles hooted. Contact any service technician. The circuit will differ with models and versions.
Type in the brand name of your device, in the search box [at the top right] of the display window and the Search will start at once as you type in, and will show you all the related posts. It will make surf easy.

The only logical solution for the problems people are having for the toshiba regza's tv's is to get into a class action law suite..., they contiue to sell tv's with defective parts and refuse to help the customer that spent large cash to find out they last if your lucky 2.5 years, they are junk and anyone with one will soon find out./.......

Possible fault in the convergence circuit, failure of the IC. I advice that you must not tamper on the TV but ask for the warranty replacement without even opening the set. You are entitled to this service and must not throw it off. So call up the dealership and register your complaint .

Always go through the basics before you post questions.  All I did was reset the TV (unplug for a few minutes) and it is back to normal.  Lesson learned, TV fixed, thanks.

SCREEN GOES BLACK AFTER 1 MINUTE


In electronics dust has nothing to do. cleaning will not solve your problem your problem is due to trouble in vertical section. mostly it is due to electrolytic capacitor in vertical section is defective.it is common problem. also check supply to vertical section. "THE SCREEN SHRINKS TOWARDS THE TOP OF THE SCREEN FOR A FEW SECONDS BEFORE THE PICTURE TURNS UPSIDEDOWN THEN TURNS BLACK." is called fold over. regards thanks

Sounds like a problem in the main power regulator circuit, such as a bad capacitor or regulator IC or transisitor. There are no user serviceable parts inside these sets and every thing is soldered into place. I recomend that you call in a trained service tech to assist you with this repair.
