Hi,

I'm the one who posted a few weeks back about my projection TV going out.
Well, the drama continues. I finally received the back ordered part only to
have it not work. Called the service company and explained the situation.
They said tech will call back. Still waiting. They also said tech might come
out to see what's going on with it. Either I received a defective part or I
received a defective diagnosis. Either way, I don't even want to talk about
my so far out of pocket.

By the way, if anyone is interested in what happened with the TV after
replacing the part, I will gladly share.

More than likely you received an incorrect diagnosis especially if it
was done over the phone. And unless you repair the same devices
over and over again becoming able to do so in your sleep, it's not
uncommon to misdiagnose ailments with a print in one hand and a
voltmeter in the other.

Actually, the service technician made a service call and physically
diagnosed the problem. I also paid for it. I was a bit apprehensive when he
used no tools. He claimed that just by the symptoms coupled with his
experience, he knew the cause. Being in the troubleshooting business myself
though, I figured he was correct since I can also diagnose by
symptom/experience only.

Anyway, I think it's better to have him check it out before condemning a
prefectly good part. Otherwise, that would be unfair to the supplier.

Is the symptom the same, or has it now changed?

It has changed. When I initially turned on the TV (right after replacing the
board), I got the "no signal" blue screen. No problem since I didn't have
the cable hooked up yet. It also made that familiar doddle doo sound when I
turned it on. In other words, all was normal. But within a very short time,
perhaps 30 seconds or so, the screen went blank. I turned off the TV, then
turned it back on. This time, no screen, no startup tune, and the red led in
front was blinking. Also, the deflection board was making an
intermittent humming sound, and I noticed the heat sinks warming up rather
quickly.

I finally got the truth from the service company who have been playing a
game with me. They just kept blowing me off figuring I would simply
disappear. I informed them that I would replace the part, and if it still
does not work, they would be hearing from me. The guy on the phone told me
that my $80 got me a "guess". Can you imagine THAT? $80, and all I get is a
guess? I don't think so. I paid for a diagnosis; in other words, the
solution to the problem. If all I'm getting is a guess, I could of had one
of my buddies come over and do it for FREE. I never heard of such a thing.
He proceeded to compare their business with the medical field saying that
doctors only guess. Well "guess" what, when a doctor misdiagnoses, they get
sued for malpractice.

I think I will cut my losses early. The good news is the supplier said I
could return the part for a refund. If I successfully do so, I will chalk
this one up to a learning experience and simply purchase a new TV.

[I tried responding several days ago, but was having internet problems.]

My suspicion about the guess diagnosis seemed to be correct.

I just got done taking out the new board and reinstalling the original. I
can again turn on the TV, change channels, and get perfect audio. Seems
everything works except the screen is blank. Same symptoms before I took it
out. This tells me that there is a defect in the replacement board;
otherwise, shouldn't I at least get audio, steady on light, and start up
tune etc. just like I do with the original board? I also noticed that the
heatsink around the flyback transformer (original board) is totally cold
(after having set on for a while), as well as some of the other heat sinks.
Frustrating since the board sets me back only about $170 total; and well
worth it if I can get the picture back on. As it stands, I'm pretty sure
they will give me a refund, and I can be done with it. But if the problem
truly is that I got a defective board, I'll never know without trying
another. However, if it is NOT the board, I'm not so sure they will allow me
to return a second one for refund. I'm now wondering if some other component
could be damaging the boards. But then again, the original is allowing sound
etc. where the new one doesn't. Strange!
Any input will be helpful.
Thanks

I've done this myself many times. Be so certain you've nailed the
problem only to find out it was something else. I did a lot of
manufacturer and extended warranties on major VCR brand. One Gold Star
brand/model received for service almost 99.999999% had a failed mode
switch. I repaired hundreds of them, could almost do them in my sleep.
I got pretty greedy being paid a small salary plus a certain amount
depending on the piece that I started to skip an actually test before
boxing them up because I could repair a couple more a day. After all
I'd never seen any other problems with this particular brand/model.
That was until 5 of them came back one day with a different failure
responsible for symptoms similar to a mode switch. Moral to the story,
everyone can and will make plenty of mistakes no matter the
experience. I try hard to not allow my mistakes to cause collateral
damage which is another subject.

Haven't responded to this post yet. The only thing I have to say is I
shipped back the board yesterday. I will report on the outcome.
