Vertical Collapse on my 35" MITS CRT

I'm sure Richard can help but I thought I'd see if anyone else had input. Last night when I turned on my Mits 35" CRT there was a very loud POP and now the picture is one thin horizontal line about 1/2" tall across the screen. Google says this is "vertical collapse".

At first I thought the picture tube was blown but after some research it sounds like it could just be a bad power supply or one bad component that can be replaced without spending an arm and a leg.

This TV is in the family room off the kitchen and is used for casual viewing. I have a 55" RPTV in the basement home theater with a full sound setup for serious viewing. My plan was to move the 35" Mits upstairs to the sitting room (not looking forward to that) where my wife watches TV, then move the 55" RPTV to the family room for casual HDTV viewing and get a front projector for the basement. The projector and screen I want are $3K and I wasn't ready to spend that much right now.

If it can't be fixed cheaply then I'll probably get a 50" plasma for now and keep the 55" RPTV in the basement for another year or two. Anybody have experience with this type of failure?

I'm not a repairman but I've played with this many years ago. It sounds as if your horizontal oscillator has taken a dump. If you are going to farm out repair, it might be better to just replace the TV.

Yes, it is called vertical collapse!

It is definitely worth repair for what it is, quality SD imaging. On the other hand she has some years and it could be 1-3 years older than you suspect - it's on the back - we'll be asking for the model and year. I'll have Alexander contact you with the details. :)

And for those wondering if I do national service... akirby is a local! :wink:
