Re: TV screen problems

If you cannot move the cross-hairs in either direction vertically or horizontally while in manual convergence mode then you may need to replace both "stk's". First check to see if you have any blown convergence resistors. (1 watt 6.8 ohm axial lead fusible resistor for Philips 43PP9202) There are 12 of these in pos. 49 - 60 that are designed to turn color other than original color code blue, green, gold, gold when blown. Should then be easily identifiable for replacement. Moderate soldering skills are all that is needed to replace $15 ea."stk's" ( stk392-120) and .69 resistors. Save yourself over $300 on avg. if TV taken to a repair tech.

Call a service man dont mess with the convergence if you dont know what you are doing if they are out of adjustment then something changed in value and need to be replaced your attempt at adjusting will cost you more than if you leave alone and call service man del,s service co

You will most likely need to have the convergence circuit repaired. Not an uncommon failure with CRT projection televisions. Go into your menus first and check the convergence settings and see what happens.

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....

TV screen problems

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 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!
