Re: Mitsubishi Projection TV Loses Sync

It did turn out to be caps on the horizontal output section. I pulled checked and replaced 5 caps. The only one that really tested bad was C5A10 which is a 100uf cap right next to a large heat sink and transistor.

Re: Mitsubishi Projection TV Loses Sync

I didn't look much in the deflection end of the frame. It sounds like I need to check out the horizontal down there.

I managed to get a picture of what I'm seeing. Definitly a horizontal scroll. It took a few attempts with a slower exposure to capture it.

Thanks....

I have a Mitsubishi WS-65613 TV that has developed a problem. After the TV is on for a while it will suddenly appear to lose horizontal sync. Actually I could be wrong on that. The pitcture just becomes a mess. So far we have been able to fix the problem by turning the TV off and right back on again. We don't even have to wait for anything to cool down.

That right there has me a little puzzled. It seems problems often get better as they warm up.

Once the picture goes bad it doesn't matter which input I put the TV on.

This is not the commong cap problem...
