Sony Micro-TV 5-303W Blank, white raster.
 

I found a really nice looking little sony micro TV on epay for $10. It has some problems. There is no audio whatsoever, and the screen displays a blank raster no matter what channel the tuner is tuned to. Are there any common things to look for in this set that would cause a loss of signal after the tuner?

Mine had a buzz in the audio from the time I got it in the 80s. Eventually the audio went out entirely. I put off tackling it as I thought these would be a bear to work on, but they really are not. In fact, they are pretty easy-modular chassis. New caps will do wonders. That's all mine needed. I think it's pretty fun to recap little transistor stuff like this.

Mine has green poly film caps and ELNA electrolytics. Im guessing its the electrolytics that need to be replaced?

Yes, that is all I replaced. I only did the sections that were causing trouble. I also have a slightly newer model with UHF that had numerous problems; new electrolytics solved them all.

I've gone through pretty much all the electrolytics and still have nothing but a white raster with retrace lines. Are there any specific transistors that commonly fail in these sets? Im guessing the problem lies in a section common to both audio and video. Would anyone happen to have a sam's for this set?

I have scans of most of the Sam's folder. Let me know if you need them and I'll post them to my web space so you can download them.

Andy,
I would be interested in the scans also as i have two of them to get working.
Thanks,
Tony
