It will not stay on after you power it up


Replace Both of the STK ICs,they are big black ICs and will be mounted to big Aluiminm Heat Sink
they will have part number on them STK392-110,use 120s or 150s also check all of the resistors
in front of ICs Low ohm resistors RK42 RK46 RK50 RK58.
Mats Electronics has Parts 1-800-628-1118 Ask if they have Convergence repair Kit.

Looks like I have 3 different colors of the picture....red shadow and I think the other shifted color was blue...


Replace Both of your STK ICs STK 392-110s use 150s or 180s they are Big Black ICs will have part number on them. Call Mats Electronics for parts 1-800-628-1118 also replace these resistors RK42,RK46, RK50, RK54,RK58, RK60.

Blue droopy line in middle of tv, everything yellowish above


Your convergence ICs Stk-392-110s Replace Both ICs.If 110s use 180s if 020s use 040s other wise Go by number on ICs .Mat electronics has parts 1-800-628-1118.Thats Cheap for 300.00 if you only have to replace ICs! Check all resistors around ics replace them if burt/read bad.RK42 3.3ohms RK46 1.8 RK50 2.7
RK54 1.5 RK58 3.9 RK62 2.2 ohms.

Replace Both of your STK ICs convergence ICs STK392-110 use 150s Better ICs Call Mats 1-800-628-1118 Also RK42 RK46 RK48 RK50 RK54 RK58 RK60 will have to get back to you on resistor values

Blue won't line up at the top in digital array


you need to replace both convergence ICs and the six 1 watt feed resistors. The ICs are both STK392-110 and the resistors you need one of each RK42 3.3 ohm 1watt, RK46 1.8 ohm 1watt, RK50 2.7 ohm 1watt, RK54 1.5 ohm 1watt, RK58 3.9 ohm 1watt and RK62 2.2 ohm 1 watt.
You can get replacement ICs and resistors at the following link with free instalation instructions.

Blue convergence


Thats the classisc sign that you need to replace both convergence ICs. You will need two Convergence ICs STK392-120 and then six resistors they are RK42 3.3 ohm 1watt, RK46 1.5 ohm 1watt, RK50 2.7 ohm 1watt, RK54 1.5 ohm 1watt, RK58 3.9 ohm 1watt, RK62 1.8 ohm 1watt. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures so you can repair the set yourself. Heres the link.

The magic focus is off on my 53udx10b....how do i fix it and if i need parts were could i get them from?


You will need to replace bothe STK392-110 Convergence ICs and the six resistors . You will need two 3.3 ohm 1 watt metal film resistors for RK42 and RK50, then two 1.8 ohm 1 watt metal films for RK46 & RK54, then one 3.9 ohm 1watt metal film for RK58 and finally one 2.2 ohm 1watt metal film for RK62. You can get the two replacemnet ICs and the resistors at the following link and they will include fre instalation instructions with pictures so you can do the repair your self.
Here is the link.
