Mitsubishi CK-3526R

My 14 year old Mitsubishi 35" console has finally given up the ghost. For awhile it was having a problem with the vertical. When turning the set on there would only be a single horizontal line running across the screen. A shart rap to the side of the box would get the vertical back again. There was also an intermittent problem with the set not turning on. It would click on and then a few seconds later shut off. Well now it doesn't turn on at all anymore. Just clicks on and then shuts itself off. I know nothing about TV repair, though I did repair mainframe computers years ago and my wife is currently a computer hardware engineer. Not sure it's worth having a repair person look at given how cheap you can get large tube TV's now. Anyone have any opinions on whether it's worth fixing? The console is in great shape. If anyone in cental MA is interested in a non functional CK-3526R for parts let me know. You would have to take the whole thing.

The CRTs in these have held up quite well. We repair them all the time. The CK-3526R will have anywhere from 1-3 dozen bad capacitors at this age. Your horizontal line was likely bad connections in the vertical output stage, likely made worse by corrosion from leaky caps. The intermittent power is likely bad caps in the power supply, and/or protection circuits. Likely all of these and more circuits need to be checked carefully for leaky caps. We only service these if the client approves an estimate that allows us to check every cap and replace the many bad ones. After repair the sets have been very reliable again. Typical repairs in our market are about $450. I would definitely have it serviced if the pix was looking good before it failed. Remember that you will have to get a stand or cabinet to replace this one, which had its own cabinet.

You want give it up or you want to try a repair ? Probably something in the vertical deflection short-circuited... and the tv goes in protection mode. It isn't complicated, you can start opening the tv and seeing where the two vertical yoke cables end. Then you can see the vertical deflection circuit... an IC... or more simply open the tv and see what ics are in...

This set is well known for electrolytic capacitors that leak. At this age there are likely 30-40 bad caps, corrosion damage and probably a bad vertical output IC. Unless one is going to thoroughly clean and rework the boards, check every polar electrolytic cap, and the CRT is in very good shape, the set is not worth bothering with. If these conditions are met, it can be a nice set. Just did one last week and it has a stunning pix for a set this age. These CRTs hold up quite well.
