Default Philips 60" convergence problem.

First of all, hope I am in the right place!

I have a Philips/ Magnavox 60" rear projection TV. Model # 8P6044 C101. It was built in Jan 1999, so it's not exactly new!

I inherited it from a friend of mine early 2007 and it was looking a little green. Had a hook up at a TV repair store help me out and it had a good picture until last weekend. The picture would shrink from all 4 corners, then go back...over and over again. I did a little work and it seems to be a problem with the convergence board. Found some more info that it seems the solder joints on the convergence chips crack and short out, blowing the fuses. (if I am on the right track, please let me know!)

I took off the back and immediately noticed a lot of dust; cleaned it off and found the convergence board. Took pics so I would know how to put it back together and removed it.

Now, the problem I am having is that all the how-to pics and vids I find seem to be on other models and I am having problems locating the convergence chips and fuses, so I know what to test. Is there any schematic out there that I could access to point me in the right direction? I already know that it's not worth it to repair the TV since it would cost more than it's worth. Replacing it isn't in the budget at this point either, so that's why I am wanting to fix it myself. My family and I have gotten to like the larger screen, so the smaller TVs in the budget won't work!!

And of course, any help would be appreciated!

Sounds to me like a power supply problem but I could be mistaken...

If you could post a picture of the convergence grid while the anomaly is occurring, It'll help with the diagnosis.

Cold solder joints on the convergence ic boards or failed/failing chips are part and parcel to your vintage display (and newer crt rptv's as well).

Post the pix if you can.

But now I do!!

Here is a link to the video. Taken with my cell phone, so it's not a great quality, but it should do.

If you can't see it, I will try to host it somewhere else.

Found a service manual for my TV here, there are 2 I can download and the price is $1 difference...any idea why? Would this be worth it?

Wow, that is bad...and a confirmation of my initial thought.

Not convergence issue. Try to reduce the contrast/picture/white level down at lease ten notches.

If the fluctuation reduces to some degree, The power supply is an issue.


The bad news..... $20 for the SM + $300 parts + $250 technician.....Min.

Just saw a 46" panel advertised for $700 Somewhere... brand new. The Philips/Magnavox brands were not close to "cutting edge" in 1999, far from it.

Cut those losses,

Ok, thanks, I will put it back together tonight and check that out.
So you are saying that the power supply is surging causing the picture to fluctuate? That doesn't sound too hard to fix, but I am guessing that is the $300 part?

Not really looking forward to bringing the 20" from the bedroom to replace this one...guess I really need a good friend who works on TV's!!! LOL

Thanks for all the help guys.

Went to the local TV shop and found out that for one, my guy at the local TV shop is still around and he confirmed the power supply problem. He actually owns a Philips that is doing the same thing, lol. He said the problem is that you can't find parts for them, so I guess I will look around a bit and see if I can find a power supply while I look at new(er) TVs.

Haven't decided if I want to spend a couple hundred on a rear projection (have the room for it) or if I should get a LCD or Plasma...both of those would probably entail a loan...

So, more suggestions? I have no experience on the good and bad of either types of flat screen TVs.

Since you are used to the quality and depth of a rear projector, plasma would be your best replacement solution. You can get a 50" for around $1000 that will look better than your projection set.

Cool, just looked at some sets last night. Looked at some Mitsubishi 73" DLPs that looked real good! They also have a deal that if I buy the 73", I get a 45" Panasonic plasma for free...guess I will have to see if I can get the financing....they start off at $2K which is a bit more than I have!

That DLP will require periodic bulb replacement at the cost of $150 to $300...

But how often will that happen. Are we talking 6 months, year, or 5 years?
