Question about Philips Magnavox 51MP392H Rear Projection Television
Mine is having the exact same problem! Has anything helped?
Mine is due to failed convergence circuits. Two chips need replaced. See best solution posted by richcradio below. Different model but same fix. If you can solder it's a fast, cheap repair. If not, I've been told it's somewhere between $400 - $600 for the repair dude to come and take care of it.

I had the same problem where all of a sudden it started bowing on top and bottom and the colors were bad. I read on here and other sites about the 2 convergance chips so I figured why not try as the tv was going to get thrown away because I could not find anyone that would touch it. Well I ordered 2 stk392-120's (I know others are saying use the 150's or 180's but I just wanted to put the same ones that were in there) I ordered them from electronix.com for 9.99 each plus 6.60 for shipping they took 3 days to get here and I installed them tonight and it worked great. The whole thing took only about 2 hours from start to finish. Here's a couple of tips....the chips are on the far left when looking at the tv from the back, make sure you mark with a marker where the wires go that you have to unplug as there are about 10 of them, each chip has 19 pins that you will have to soder make sure you have a soder ****** to get all the old soder up as you are heating them up, after you are done puting it back together leave the back cover off and turn it on, then go into your menu and go to pictureand go to manual converge and go to undo multpoint and restore factory as this will reset it all. Then if your color is still a little off as mine was there are 6 knobs in the back of the tv by the chips you were working on, find a channel with a lot of colors and try adjusting the top 3 a little at a time till you get the right color that you like. This should do it. It took 26 bucks and 2 hours for me to fix a tv I was ready to replace, thank god for the internet to be able to look stuff like this up. Good luck!

It's pretty simple repair. Pull bezel, unscrew braces around edges and swap screen out. Where did you find the lenticular at? I have the same TV and can't find the part online.
