It's probably full of leaking caps, but worth saving (not for $180).

A friend had the 31" console version of one of those and he paid about $1600 for it, circa 1989. It was trouble from the start and by the mid '90's, the CRT started getting weak and I rejuvenated it. It ran a couple more years and something went wrong with the power supply, that I fixed. By the early 2000's, it started giving vertical problems and the tube started getting weak again. At that point, it became a stand for another set and he eventually gave the TV to me. I rejuvenated the CRT (again), replaced some bad capacitors, and donated it to the starvation army.

I can't imagine $180. He had more than that on it at first. I paid 25 for mine and everything's good except those caps.

Its a Bose set so worth extra. If you have bad caps
in the vert change them FAST. The vert IC has been
disco for years & very hard to find. The vert, HV & power
supply boards should get new 'lytics & be checked
for cold joints. Thats about all that went on them.

I've also seen a lot of leaking small caps on the main board of those sets. They're easy to overlook because it's completely enclosed in a metal shield that's a pain to remove. I haven't worked on one for over 10 years, and they were usually leaking then, so I can't imagine they've gotten better with age...

I passed on a Bose system 3 like that at a garage sale 4-5 years back, thinking I need to draw the line with my Zenith TV obsession at CCII sets....The more I hear and see of these digital system 3 sets the more I start to want one....

I wouldn't trade mine for anything. I especially like the better sound and the Chinese cabinet. I have caps to change but I don't run it. Is there a such thing as a kit or list of caps I'll need or do I just start pulling the obvious ones and replace?

Just open it, take note of the value of capacitors that you need, and replace them. When you replace them, use high temperature types and a decent brand (Nichicon, Panasonic, etc.).

Haven't these idiots figured out that you can lower the price; but, you can't raise it? When something does not sell, it's often because the price is too high and the price needs to be lowered until the item sells.

What do you mean they can't raise the price?...They can raise it as much as they want, but it only reduces the chance of selling it.

old sales technique.if it doesnt get any response,change the price.if you increase,the buyer may think you have done research and found it to be worth more.we did this all the time in sales.when i was a trainer this was one of our best gimmicks.

The seller probably saw the traffic (views/hour) and thought it was a "hot" item that could sell for more. You couldn't give me one - hated them when they were debuted. Zenith did a cursory service clinic and suggested module -level repair only...

That's sad. Sounds like backwards engineering. That crap doesn't work on me. I buy when prices come down. Increased pricing turns me off.
