    I also have a red convergance problem with a bow in the bottom left hand corner. Would like to know if there is simple fix to the problem.

You will need to replace both convergence ICs they are STK392-110 and you will also need four 6.8 ohm 1watt resistor. You can get replacement ICs and resistors at the following link with free installation instructions.

Bowed picture on Philips 55pp9352 after replacing IC's


You must have mishandled the ICs they are static sensitive, and unless you used Sanyo ICs then you will have problems. The convergence is obviously not working so the TV will need the digital convergence board repaired or replaced, also the PIP board is suspect I have seen plenty of these tvs and believe me I earned the $ 350 we charged. These sets are very difficult to work on even for a trained tech. the best thing to do is to have a repair shop do it and you will have the assurance that its done correctly, and the work is guaranteed, That makes sense. ( I will not be able to respond to any further inquires)

Red curves on bottom and top of picture


You have a convergence problem. Here are some of the most common symptoms. 

Screen looks 3D
One or more colors can't be adjusted when when using the convergence menu. 
Screen is bowed in but stationary.

Solution: 
You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kit for your exact model. The kit inlcludes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. Everything you need to fix it yourself. Its an easy fix.

Philips Magnavox 51MP392H Rear Projection Television


are you getting sound, was it moved laterly, did you just get it from somone, did it get wet, does it make clicking noises, was the picture color/ convergence blurring before this, were the colors slowly seperating such as red/blue/green?, did the picture bow on top and bottom or sides prior to tihs, was there anything note worthy prior to the blank screen.

generally its IC convergence problem with the larger philips projection TV's however I need more info on your TV, also size make model # anything you can provide gets us a more narrowed solution.

hope this helps....

50P8341 red bows


Convergence ICs or the resistors powering them are bad. Check for open resistors near the ICs if any are open, change both ICs and the resistors.

Picture Quality


Sounds like your convergence amps are probably bad. Check out http://i114.photobucket.com/albums/n248/OFilippov/Dont%20look/Pioneer/BadPicture03.jpg and see if you have similar bowing between red and green when you try multipoint convergence. If so, you'll need new convergence amps, part STK392-120. Most people who are handy with a soldering iron can replace these parts in a couple hours.

Blue out of whack around sides


I have the convergence problem with the red. After reading your site I replaced the 2 ICs and the problem is worse. Before the only problem was I could not adjust the red horizontal. Now I have no control over the vertical or horizontal and the overall picture is very red and it bows at the top and bottom very bad. A friend said I might have the ribbon connector in wrong or the convergence (silver box?) box maybe bad. Any ideas? Thanks,Dave.

Warped Picture, Separated colors


Each color (red,green & blue) has an amplifier IC (STK-).
When there is a convergence issue,the first step is change both
IC's for reliability. Then check for open fuses devices,usually
pico fuses.Then re-check convergence alignment.......T.
