I have a trintron 40xbr800 stand by light blinks 7 times tv has no pictcher

Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206. Might be of faulty IC. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now. Pull up older posts there.

Six blinks points to No Horizontal or raster. The uProcessor detects a problem and enters the self test function shutting down the main power supply.

How many times does it blink in between each pause? This is a self-test diagnostic code that will help us locate the source of the problem. So please count carefully and let me know.

Sai.

you have a major problem that requires repairs. which are usually more costly then a new tv. A used/new one on craigslist is a great budget saver

Hello
Your tv has problems in power regulator side, which is in the printed circuit board of the telivision. Sometimes it may due to some socket contact problems. You just contact a technician., while you cannot do it right by yourself.

i have a sony trintron at home from my observation if you set to much of brightness the tv will start blinking.
the other prevention is that you need to take the tv for service so that semiconductor can be changed, zener diodes and electrolitic capacitor before the tv goes completely fault, like that it be comes cheap and first on the tech to change components.
as time goes these components changes conditions so they need changes from time to time
okay

My Sony XBR800 won't start and the standby light blinks 7 times with a 3 sec. interval before blinking again.

30 YR SERVICE TECH.
YOUR UNIT IS EXPERIENCING A POWER SUPPLY FAILURE.(INTERNALLY)
TAKE TO A SONY AUTHORIZED SERVICER.
