Pioneer SD-533HD5 on the fritz

post #1 of 9
Thread Starter 
Suddenly and for no apparent reason the geometry on one or more tubes got distorted.
The convergence is all screwed up and though I can correct it in the center of the screen, it remains distorted everywhere else.

The grid on the multipoint convergence screen is very distorted and it's impossible adjust toward the outside. Even if I could get the lines to converge, the grid isn't square so geometry would be screwed.

She's way out of warranty so I'm considering taking the back off and seeing if it's something mechanical. I'll probably have to call a service tech.

Any thoughts on what the problem might be?

I'm in Santa Rosa, CA. If anyone knows any good service techs in the North Bay.

I just had a service tech on the phone tell me that it's probably the "convergence chip".
He seemed to indicate it was an issue with these sets and needs to be replaced regularly.

What's the BS meter on this?

They just don't "go out" every few months.....

To clarify, he indicated that they go out after a few years.
For a solid state device that tells me it's poorly engineered.

He said "Your set is probably a few years old and has never been serviced right?"

My set is 5 years old and has never been serviced.
I'm sure it needs to be cleaned in any case.

Good technicians are hard to find, even harder is to find ones that are cheap and give you full service.

If you have someone come out and do it then do it, and also ask them if they will also clean inside also.

The lens tops at least need a cleaning, deeper optics cleaning may also be needed.

I don't see how they say it is HD when it only goes up to 480p and even then it is just a line doubler....
WTF it says it doesn't even have component inputs.

My 533HD5 has two component inputs and does 1080i just fine.
It does not support 720p however.

EDIT: It takes native 480p from my progressive DVD player also.

Weird. I looked at some specs of it and it said it only did 480i and 480p (which I am guessing the doubler just makes it 480p), but didn't read anything about component inputs.

A cleaning will DEFINITELY improve the picture, along with the repair, you will be glad to pay up :P

I have an SD-643HD5 that has done the same goofy geometry. I have two IC's on the way. Does anyone have the service manual for my unit? (June of 2002). This is what I've ordered: 2 x STK392-120's. I understand the -110's go faster.

As a previous poster requested: What's the BS reading on this?

Thanks,
