    My sony KV-32TW77 does the exact same thing, it started out as just blinking off and on when it was first turned on and then when warmed up it seemed OK for awhile and now it just constantly blinks off and on...



    Thanks, Rickya

Unfortunately that's an indication of the crt going bad in a Sony.
You can turn the G2 voltage down on the flyback or have a tech rejuvenate the picture tube but either of these are only a temporary fix..
The flyback is the rather large transformer with a red (anode) wire coming from it and attaching to the crt. (looks like a suction cup).
There are two adjustments on the back of the FBT, one is screen (or G2) the other is focus. With the unit on turn the G2 counter clockwise just a little and the picture will get slightly less bright. That should stop the picture from blinking out - or doing so as often. But again, it's only temporary!
Good thing Santa's almost here... :)

Repair tv


You didn't say anything about the model or make but a lot of times this comes from bad capacitors...try this...on the open fins on the back of the TV, try putting a blow comb on there and set it on low and leave it there for about 3 minutes, turn the set on and see if it comes right on, if it does there are bad caps on the power board, it could be replaced or you could repair it yourself for a couple dollars

Samsung le40f71bx picture flickers on and off with hd source


I've had similar for a long time, now the picture only lasts a few minutes or seconds. Have to turn the TV off, wait 5 minutes, turn it back on. That's with Sky HD. Used to be the same with SCART but I don't use that any more, and I get it with the Wii on Component. However HD DVD and Blu Ray players are no problem!

See my post here - http://www.avforums.com/forums/lcd-led-lcd-tvs/1622157-samsung-f71-flashing-pattern-fault.html

Way out of warranty but really just need some repair expert to tell me what needs fixing. Taking the cover off there are very few components and look easy to replace, and seen some on ebay. A fix from Samsung would be vastly in excess of the value of the TV.

You know how to reset the tv to its factory setting, I think you are a technician. Second thing you can do is software update. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 . If it doesn’t work. Replace the Main board (UB board). Part # A-1547-086-A Cost approx $320.

TV switch light flickers 11 times but no function


Hopefully it is only a board component that needs replacing and your dry joints that need re-doing. I would advise that you take it to a television repair shop as this type of repair can be very complex (replacing resistors and capacitors just to name a few).
