Sony Trinitron PVM-20N6U Picture out of focus

I recently had a flood in my basement and my Sony monitor sat in a couple inches of water for a couple hours. After letting it dry out for about 2 weeks I powered it up and discovered the picture is out of focus. How can I adjust this problem? Or is the monitor shot?

Protection circuit fault kicks in. No vertical Deflection (V STOP),B+ over voltage protection (OVP), This is about a $150 -$200 to fix.

This can be a symptom of the picture tube starting to fail or a power supply problem. Can you please verify the model number and I'll then be able to give you a few options.

Thanks,

SOURCE: Sony Trinitron Picture Tube replacement

I think that you will find the picture tube to be more expensive than a replacement TV, if it is still available (unlikely). That being said, it is also unlikely that the tube itself is the problem, The more common problem is the horizontal output transistor or the flyback transformer. Either part should still be available for a reasonable cost. Check with a local servicer for the part numbers and costs. These are common parts.

SOURCE: Sony Trinitron XBR TV, picture-in-picture got

A solution I found for our KV-32XBR200 was to press Setup on top of the set, then select the "Demo" item with TV/Video. The text overlay apparently banished PIP. Verified this twice, as I'm at this page because our remote can only turn PIP on :-).

What can I do about my flood-damaged monitors?


I would strongly suggest putting an insurance claim and replacing them. Water damaged cabinets may swell and come unsealed over time, as well as the speakers themselves and the electronics degrading faster than you might expect.

If you are comfortable with working inside the set where there are potentially dangerous high voltages present, you can probably fix this easily. Open up the back and remove it. Plug the set back in and turn it on. In the lower right hand side will be the flyback transformer (large red wire coming out of the top and going to the side of the picture tube). DO NOT TOUCH IT!!! On the back of the flyback should be 2 "knobs". One will be marked screen and the other focus. Carefully adjust the focus until the picture is clear. When you do this, go beyond the clear point and work the control back and forth a few times before settling in to the focused spot.

That should resolve the problem.

Sony Trinitron - Picture Disappears


Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider
