My new sony 26 inch bravia lcd tv suddenly loses signal

Any other indications? It looks like it turns itself into 'stand-by' having no input signal.

You have intermitant problems which may be caused by contact resistance or circuit overheating.After it cooled down the tv starts again. Leave TV on standby at all times.

I'm afraid, its problem of LCD Panel (screen).
LCD Panel replacement is only solution for this problem and will cost you 70% of TV price, please contact nearest Sony service center for LCD Panel replacement.

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

hi! maybe there is a problem on power supply section or loose connection.

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

The tuner is bad. Could also be the video process, since the hi-def is decoded there

COULD BE LVDS CABLE LOSE OR NOT MAKING A GOOD CONTACT , IF IS NOT THAT UNFORTUNATELY IT WILL BE NECESSARILY TO REPLACE T CON BOARD
YOUR RATING TO MY ANSWER ITS HIGHLY APPRECIATE
THANKS

You have a bad LCD panel. Hopefully it is under warranty still as they are expensive.

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..
