Question about Sony KV-27V22 TV

1 Answer

Sony trinitron KV27V22

Picture is ok for about 30 seconds when TV is turned on, then rolls about half way up the screen and shrinks in on the sides with the edges being jagged. At this point the picture is very distorted, then the picture goes black.

My hunch is the horizontal control.

Sony trinitron

check the heater as your tv is ON, there must be a yellow light at the rear of the CRT tube. If the heater is ok then check the IC jungle side. resoldering the leads sometimes will solve. If not refer to your local Tech.

After a few minutes picture shrinks to single line on screen and then powers off

Since the set works initially, there are likely poor solder connections at the vertical IC. If this is not addressed soon, the IC will fail and need to be replaced. The vertical IC is a small flat IC with about 11 pins or so that may be marked LA7837 or something similar. Try resoldering the pins first. If that fails to resolve the problem, replace teh IC. Feel free to post the marking here so I can verify you have the correct one.

Picture broken and shrinking

You need to change your vertical IC, along with some capacitors around the vertical IC. Capacitor with value 220UF, 10uf, 470uf and finally 1000uf. Doing this will fix the set. Total cost under $40

Sony Trinitron kv32fs16 picture shrinks

You have a bad solder connection in the vertical circuit. This will require you to resolder these bad connections before it blows out the vertical output IC or other parts in the circuit. Do this ASAP before you make a small repair into a large one. If you have no solid state printed circuit board experience, please play it safe and take the set into a pro to do this for you. Good Luck

Green screen with almost horizontal zigzag lines

Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
