How to fix problem of jvc crt tv model av-21l31 power ok no video/audio no display with lines coming from flayback


Look at the horizontal output transistor then the fly back transformer.Check ALL the voltages coming from the power supply. One or more of them have to be missing for the audio and video to be gone at the same time.

Power supply transistor transistor no. C4237 replaced 4 times. each replacement didnot sustain for a week. which transistor can i use instead.


I have worked to repair a few of these. When the transistor is burned, you most likely have a bad flyback transformer and bad picture tube. In this case you replaced this (transistor) component four times. This TV cannot be saved. Thanks for asking.

AV-27BM5 relays click on but no picture,high voltage or sound


It's been my experience that symptoms that point to the power supply, generally are not the case. Schematics now days are tough to find unless you are an authorized servicer for that brand. There are a couple of generic dealers out there but they don't carry everything. Before you replace the power supply I would suggest you go though other boards first looking for bad solder connections and/or transistors and IC's that may be defective. A good DVM with an ohm's scale should suffice. If you still can't find anything, I would suggest taking it to a reputable repair person.

No power


Replaced the C226 capacitor. Using advice from this web site, found the capacitor, and yes it looked burnt, went to Radio shack and for $1.69 bought a new one, put it in, and we were all set. Does have to be soldered in, in all it took us about 1 1/2 hours. Thanks for the tip.
