Sony Trinitron screen flashing

sounds like it's toast http://community.sony.com/t5/Television-Picture-Sound/Vertical-Lines-of-death-KDL-52W4100/td-p/29582

there might be a problem with the connection of the screen to the motherboard or the wire that connects it might be the fault. but there could be a burnt fuse or components.I would suggest letting a tv tech have a look good day sr

My Sony trinitron has the stero lite on steady and standby lite flashes four times then pauses and repeats. Can you tell me the circuit/condition causing the set to not turn on.

Forward voltage/current problem....needs a new board....You might try unplugging it for a few hours...If the TV starts you will need to leave it on until it gets repaired or replaced.

when the lights flash those are codes that tv repair men have.youd be better off buuying a new tv,they are less than 500.00 nowadays

There is some electronic circuit problem with your TV. Best if you want to repair it you find a reputable TV repair shop. Sorry.

When I turn on the TV I hear the click sound and the TV powers up. Immediatly the red (standby) light begins to flash 6 times on and off. this happenes only in the morning, but after 5:00PM when youturn on the TV as if nothing is wrong.

what is the problem?

no doubt. replace LOT and horizontal output transformer with new one

Could be a weak Picture tube . You can try turning up the screen control but don't turn it up too much you'll get retrace lines in the picture . Turn it alittle at time until picture comes on then turn it down until the retrace lines go away . Then try turning the tv on and off to make sure it comes back on. Be careful you can get shocked if you do this while it is on and you touch one of the circuits . The control is on the flyback or the module thats on the picture tube it will say screen by it . If this does not work you could have vidoe problems or just the picture is no good . Good luck

I get a black screen after power on...then a bright white light in the middle of the screen.Then the red light flashing and turns it self off.
