Re: Sony kv32v26 screen come on and off sound is ok

Power supplies give a lot of trouble (besides the tube). there are two regulators that go bad very often. they may also take out the horizontal output. there are some capcitors, resistors, 2 thyristors (i believe 2) and diodes that are suggested to be replaced along with the two regulators. all of those parts are fairly cheap so it shouldn't be that big of a deal to repair (granted that is the problem and the only problem).

Repairing a TV set is actually a skilled work. If you're not sound in electronics, make sure, that you can't do it; especially to Sony sets. If the set switches ON; with audio output OK, and there is no Video, surely the fault should be with its horizontal scan output section circuit. Check that circuit for fault. To get more details,

My Sony Trinitron 36'' model#: kv32v26 is taking a long time to show picture when turned on. The sound comes on and the red light blinks for about 3-5 min. before the picture turns on. And when i switch to...

Hi Matt.
I`ve been repairing sony tv`s for a long time now and i can tell you that what you described is sure signs of a weak picture tube.
And the price of a new picture tube makes it prohibitive to replace it. You could open the set and adjust the screen control on the high voltage transformer but it won`t last long. If you decide to do that , look for a transformer with a long and thick red wire that connects to the back of the picture tube , That is the flyback transformer and there will be two controls on it, you want to adjust the bottom control that is the screen control(the upper one is the focus).
Turn your tv on and slowly turn the screen control up until the picture shows up at a reasonable brightness level, if yout turn it to high or you may get retrace lines in the picture.
That may strech the life of your set for a couple of months .
Hope this will help. Merry Christmas

Too dark sony model kv21gmr1

Warning: The following procedures should be done by an expert.
1.First step is to check the physical condition of the set.Before starting troubleshooting try to resolder the board and find any cold or loss solder.Then after plug the set and see if the filament of the tube glows.If not the trouble is in heater circuit.
2.After seeing the filament if it glows, check the CRT socket and open it.If you can see a sign of terminal decay such as greenish unwanted element on terminal surface,replace the CRT socket.
3.If replacement does remedy the problem check RGB drivers and resolder or replace jungle IC.
4.Try also to adjust the screen adjustment found in the flyback transformer.
5.Another possible cause is the vertical IC.Adjust the screen to full and see if their is a white horizontal line on the screen.If so the problem isin vertical circuit.

Are u saying that the video and sound is ok? And that you have a vertical line moving up your tv screen? If this is correct then it sounds like an A/C hum or filter problem. This would be in the powersupply it could be a big cap that needs changing.
