Ur tv convergence board that was replaced for ur tv.The 2 STK convergence ICS was old it is not new it is those 2 STK convergence ICS on the tv convegence board is dead again and some of the resistors on the board maybe shorted and dies also must replaced too.The tv convegence board was put on ur tv those parts on the convergence board are old components parts,ur must repair tv convergence board again to fixed this problems called convergence pictures problems.

Yes,the convergence problems it the cause,but also now could be have addtion some other problems too it.But change the 2 STK convergence ICS and all the resistors to it, fix the convergence board first see what happen.

We have a Philips 60pp9401, 60' rear projection tv. The images looked like they are layered. How do we align the colors without the original remote control? Using Intellisense.


U can't alignments this even u have the original remote.Tv have a problems known as convergence problems,it dead.Colors lines R,G,B mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors too.These parts,must be changes on the tv convergence board to fix convergence board to solved the tv convergence picture problems.The shop,will cost u like $300-350 for parts and labors.

Convergance- Red X will not move to make crosshairs white. Picture is doubled with red and blue. TV is a 55 in Mitsubishi VS55601.


Hi,
This problem is related to the Convergence controller IC called STK.It must get malfuntioning replace the STK IC with the same numer IC. But one thing is importent that there must be two IC STK's and you have to change both of them.
Thanks

Convergence gets very bad the longer the TV is on.


The convergence amps will have number on them starting with STK replacing thes may do the trick or you may just have a poor solder connection at these ic's try soldering them first if no go then replace them look around on the convergence amp cba on the bottom for obviuos bad connections small ring crack are hard to see these ic's work hard that is one reason for their large heat sinks running the set and turning it on and off may have induced fine ring cracks. i amsorry I dont have a schmatic for this set but the ic's do have their (generic) part number wrote on them as do most all transistors and diodes and ic's

Panasonic pt-53tw53 convergence


It looks more like an open solder because you were able to align it properly after replacing the STK ICs, if there was an open resistor(s) you would not be able to get it align.
I would suggest to go back and double check the solder joints on the STK ICs as well add some fresh solder to the resistors nearby the stk392-180.
Good Luck.

JVC AV-48WP30 will not give a picture


Replace the convergence IC`s again using original Sanyo chips (STK 392-110 or STK 392-180). Make sure to use plenty of heat sink compound. Coat the entire back side of the chips. Also look to see if any of the low ohm resistors are burned. A shorted chip will cause the thumping sound and the set will shutdown. I am guessing that you used generic IC`s as a replacement. They are cheap and the leggs fall off when you apply too much heat during soldering. Dont wory about the CRT driver or the deflection board, they are probably fine.

No picture have sound


sounds like your IC's took a dive again. Did you change them or a shop? You have to also make sure that when you change the IC's that you put plenty of heat sink compound on the back of the IC's and do not use the cheapy IC's that you can get for 20 bucks or less as I have found they do not last. This convergence board should be available as a complete board. Good Luck
