Question about Philips Magnavox 51MP392H Rear Projection Television

1 Answer

Yellowing screen off-center - not a convergence issue

I just got a used 51MP392H for dirt cheap ($250). It looks good enough, but I'm wondering what the cause of this problem might be. The screen look perfectly calibrated (for color) in the center 12 inches of the screen. The closer to the edges, the more of the picture shows a yellow hue to it. I've done the simple convergence, and the manual convergence adjusting both red and blue on all points both vertical and horizontal, yet the yellow edges persist (and are most obvious when the screen shows white. An all white screen is blantantly white in the middle and increasingly yellow towards the edges.) I also took of the screens and cleaned them, cleaned the interior mirror, and cleaned off the surfaces of the RGB lenses. No fix. I did notice that on the manual convergence menu, the crosses were more blurry near the edges of the screen, and perhaps a focus of the picture may be neccesary, and may even correct the problem. I'm hesitant to spend a few hundred dollars on having a pro fix the TV and am wondering if I can make hardware adjustments (focus?) or something else to alleviate this problem, or if I'm out of luck. Thanks in advance for your input.

You might want to try the optic lens adjustment screw on the side of each crt. Mark them before moving.

Magnavox 51mp392h rear projection t.v's power button will blink continuous and there is a low chirping noise. T.V. does not turn on.


The chirping may be the key...When this is commonly the case its a convergence short. See more details on the site www.TvRepairKits.com - Look for a chirping repair kit for your model. Its a common issue

46PP9302/17f convergence problem maybe....


You need the STK392-120 convergence amps replaced along with possibly a couple of 6.8 ohm resistors.As a technician this job can range anywhere between $185.00-$250.00.If you can solder the dificulty level will require some electronics experience.Good luck!!

51mp392h Blue Convergence Problem


Hello rogeuryder,

This is the one thing that even make TV repair persons shudder. You don't really have a convergence problem in the normal sense. The convergence works. What you have is a misaligned convergence situation which any documentation and or book on TV repair will tell you that at this point manual convergence adjustment is needed and the only thing you will have to do is keep trying to adjust the convergence until you get the center aligned, and then work towards the outer edges using both static (Center) and dynamic (outer edges) convergence techniques.

As this may sound it is; Very Very Tedious.

Here is something that may help you:

http://books.google.com/books?id=ttBofTJM7FEC&pg=PA112&lpg=PA112&dq=static+convergence&source=web&ots=hyUMeeY9s6&sig=DZm27q1aMbLiwKA__fyysBd2yUE&hl=en&sa=X&oi=book_result&resnum=9&ct=result#PPA112,M1

I have used this book when I use to teach TV repair. I hope you discover what I am tried to convey in my e-mail, this is no longer a question of can you fix a TV? It has become a question of do you have the patience to adjust a TV.

Good fortune in doing this, you will succeed if you just take your time and do static convergence first and then do the dynamic convergence with the manual controls. The procedure will be in the service manual.

I hope this helps

Thank you,

Broken Screen on Philips Magnavox 51mp392h/17


your only chance will be find one at the local repair shops that may have saved some from sets they have scraped out, But they are hard to come by, and phillips have them as no longer available as do most manufactures shortly after that model lines goes out of production. Also try www.craigslist.org as they have chapters all over the world and often people give away dead sets, you may get lucky and find one.
