Hi there, I have a 12 year old sony tv that just suddenly started having problems, first sign of trouble was that when you turned it on no picture would come up, that includes osd, and then after about 10 seconds it would automatically shut down to standby mode again, no matter how many times I tried it just kept doing this until that is I gave the top of the tv a whack at which point all was fine again for sometime but then most of the picture would disappear and there would just be flickering strips of picture near the top of the screen and then if I did not give it some more whacks it would turn off again. Any ideas as to what this could be, could it be as simple as dust or is this the last dying gasps of the cathode ray tube, why would a whack help the tube to go again?

The picture tube is likely fine, this is a problem far removed from it.Something is making bad contact, either a connector that is no longermaking contact all times, or a bad solder joint. Michael

television goes again by hitting the top of it?

When you find the bad joints use only rosin cored solder. Plumbing (Acid) solder will eat the copper traces off the PC board. I prefer a mild RMA solder like Ersin Multicore.

Did everyone miss the comment "flickering strips of picture near the top of the screen" The guy has a dry joint on the frame output IC! This could be confirmed by the standby LED flashing a fault code. Cheers John.

Don't you need to have Cinemax for this?

Thanks John, the standby led does not come on during this fault, also the picture takes on the shape of an ever decreasing upsidedown trapezoid.
