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.

Hi, Anonymous and the usual suspects are:
1. Dirt or other foreign matter between float valve and its seat.
2. Float valve sticking.
3. Float valve and/or valve seat is worn or damaged.
4. Float misadjusted.
5. Float cracked, leaky or damaged.
6. Excessive "PUMPING" of hand throttle grip.

What oil weight is best for a 1996 yz 250?

Calls for 10w30. Any brand mc specific oil will do, along with any of the more expensive brands. If you need to go cheap, buy Type F (only)automatic transmission fluid. Change as soon as oil looks dark.

Shudder when in higher gears

The most likely causes are simple:

plugged air filter
water in fuel (likely to cause trouble in all RPMs)
plugged main jet in carb
plugged fuel screen in fuel tank
faulty float setting in carb
faulty spark plug
improper timing

It's likely a carb problem if the air filter is clean and the fuel is fresh and free of water. Condensation is a good posibility (water in the fuel). I would suggest pulling the carb and inspecting the cleanliness of the fuel in the bowl for water and dirt. If you find water, dump all the fuel and start fresh. If you find dirt, give the carb a good cleaning.

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 as they have chapters all over the world and often people give away dead sets, you may get lucky and find one.
