Question about Sony KV-32S26 32" TV

Picture keeps shrinking and going out

I've been having problems with my t.v. picture shrinking and going out completely. I tried turning it off for long periods of time and it seemed to work fine for a couple of weeks after that. Then it started again so I tried the tap method around the shell and it would make the picture come back most of the time. Then it finally would just come on with blank screen and sometimes a reduced picture. I took the back off and dusted it out and then looked for loose connections and solders. Really didn't see any but did make sure everything was tight. Now I've got the t.v. on and it's been working for about an hour & 1/2 with no problems. Any suggestions as to what the problem may be? I thought originally it was a power supply but now I'm not sure at all. I'm sure it will go back to losing the picture again unless I repair it.

Pictures shrinks.. Panasonic TC-20LM Television

Shrinking picture is a voltage regulation problem in the switch mode power supply, Possibly a cap used in the feedback circuit. Or an over current condition on the B+. This is a very tech intense repair because there is no magic bullet. If it is shrinking on bright scenes then you can bet it is a regulation problem, bright scenes draw more current from the power supply causing this effect. I would not suspect the horiz output because the regulation for this circuit usually comes from the main switch mode power supply. One diagnostic is to monitor the B+ going to the horizontal output and see if it fluctuates. If so you can bet it is a cap or optical coupler in the switch mode circuit.

It sounds like a loose solder contact in the vertical circuit.
maybe on the vertical ic or some caps in the area.

Picture shrinks horizontally every few seconds.

You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.

Shrinking picture

All symptoms indicate a problem in the vertical circuit,the first thing to look for will be loose conection on the vertical output IC,sometimes this IC goes bad completly and it needs to be replaced.If you are familiar with soldering electronics you can take care of it but if you are not too familiar you can play it safe and take it to a servicer ,it will be a lot less expensive than if they come to your house.Let Us know how it goes or if you need more information.
