SOURCE: kdl-40v4150 turn on only 1 min then going black

That's either bad power board or bad main board.

Given the description it is very hard to say which of the two it is.

Frankly, considering you can get a new power board for $25 I think you should just go ahead and do it - it will cost less than bringing the TV to a repairman and as a repairman I can tell you they wouldn't have much better chance than you do...just shoot for a try and this will narrow it down to a single board.

I am not anyhow associated with the above seller. it is just the lowest I could find on eBay.

Hope this helps!

SOURCE: blank screen

The fault is with its main power supply regulator section itself. One or more voltage rail is missing. Your TV need a through checkup. Seek tech assistance.

We are having issues with the screen. The display of our Sony Bravia KDL-40V4150 shows straight vertical lines all the way across the screen. How do we fix this issue?


Sounds like a defective T-Con board, but it is better to test it before replacement. Also there is a possibility to repair it at a lower price. You can find a company that is testing this kind of T-Con boards and repair them here: http://www.coppelltvrepair.com/p/540/repair-service-for-auo-t400hw01-v5-40to2-c06-40t02-c06-lcd-timing-controller-t-con-causing-bad-tv-picture
