I have seen this happen in other Flat Screen TVs. (The Polaroid brand is one of them) You definitely have a bad power supply.As you say, shutting off the the TV and turning it back on sometimes stops the problem. First thing to find, are bad capacitors or bad grounds that need resoldered.. This is your best solution, I have repaired many howling and screaming flat screens. Thanks for listening.

Sony V lcd 32 inch losing digital channels and after doing a resetting scan it is ok for about 30 mins.... then screen image breaks up totally and message 'weak signal' shows on screen. Help,please.


You answered the question in your question.
''weak signal' means exactly that, however it can also mean the signal is too strong.

If you have a booster installed into the ariel remove it, if not, try one. Make sure the TV is directly connected to the ariel, not via a DVD recorder or any other devices which require an ariel input.

Sony tv's have very sensitive tuners installed so its just a case of making your aprticualr settings compatible.

Check signal strength over at www.digitaluk.co.uk

Thanks

Sony Bravia 46Z4100 has a thin vertical red line on the screen


I assume that when you get the line you lose the picture, if so, you have vertical collapse, either a dry joint in the vertical section or capacitors or vertical I.C., I would doubt that the scan coil would be O/C as that is rare. if you can't do it yourself I suggest taking it to a repairer, as it should be an easy fix...Hope that helps...Phil

'No Signal' on Sony XBR


on the tv remote: press menu, external entry is highlight (yellow) right press on the outer circle then scroll down to video 4 (satellite entry) (it could be on video 3 depending of the satellite assignment entry) when video 4 is highlight (yellow) right press on the outer circle on the screen you will see 1080i if settle on an HD channel hope it will fix your Sony Bravia..
