Television has double images like 3D, and bottom half of screen has a concaved image.


Hi,
Please replace convergence ICs in tv, there are two big black ICs that has number STK392-110 mounted with big aluminum heat sink, replacement these ICs will solve your tv problem. Also check big resistor nearby these convergence ICs and replace if found burn mark or color faded.
On circuit board, IC location number is IC7001 and IC7002
Let me know if you have additional question.
Thanks.

Convergence problem, now there is a smell of burning,and the tv will not turn on


The bias resistors have smoked and also taken out the convergence ic's. Best advise, have a qualified tech diagnose it.

Convergance problem on lower half of screen.smeared red and orange double vision,but only on bottom ofscreen.top appears out of focus,but not double visioned.


Howdy,

The TV has a convergence problem; the IC’s for that circuit will need to be replaced. The part(below) Number is from Toshiba, they provide good advice on replacement parts. Make sure what type of IC's your TV uses first. The cost for this repair runs around $450.00 or more.

Replace the defective Convergence Output IC Part Number
23905094 (STK392-110) using the revised “T” version IC Part Number
23135090 (STK392-110T). When Convergence Output failure is
detected, it’s recommended that both IC’s be changed to the “T” type IC
version. Inspect the Convergence Output IC’s for the “T” type version as
shown in Figure 2. Replace the Convergence Output IC’s using the “T”
type version Part Number 23135090 (STK392-110T).

I hope this information allows you to resolve this issue.

Need the correct convergence IC number for my Phillips Phillips Magnavox rear projection tv P6034C. I am getting the double picture syndrome . It also appears as if I cannot adjust the red convergence...


Thats not the full model number should be something like 43P6034C or etc. Please respond to this same post and I will let you know the correct Ics and resistors because phillips / magnavox will always burn at least 2 often 4 of the convergence resistors as well.

Replaced 2 resistors one burnt up. please help


They would only burn if your convergence ICs are bad so if you didnt change the ICs with the resistors they will keep burning.

WS-55819 Mitsubishi Rear projection TV Picture goes blurry


Convergence ICs are bad need to be replaced. You will need to replace both of them also check the resistors right next to the IC often 1 or 2 of them burn out when the IC goes.

Urgent help


ok i would suspect the yokes are shorted to ground somewhere. you can measure that. the dcu or the digital convergence unit... which is the processor that handles the convegence of the set. i would have to research and pull up schematics to know which output on the convergence chips that those resistors handle blue ver...blue horizontal..etc.. that might help to see which output is shorted.

TTV won't power up


The correct number is MC306Vome-107FP mitsubishi part # 275P363030. I am not positive that you can get that IC it is considerd obselete you normally have to replace the signal board. However I doubt that is your problem. Have you checked the chassis for corrosion due to coolant leaks?and or bad capacitors? That chassis is prone to crt coolant leaks causing PB corrosion and solder deterioration. The signal board is pricey, If you can locate one.

Convergence amp


Heat or not using the right replacement IC if it keeps burning out. If it is the first time it happened, the heat sink compound dries up, and then the heat transfer goes down and the IC overheats. If the IC is burning out a short time after you replace it, you are probably using a cheapo aftermarket type or a factory reject IC. You need to use an original replacement, not just one with the same numbers because all IC's are not alike, even with the same numbers. You also need to put new heat sink compound paste on the back of the new IC's before you replace them.

Part number for IC module Hitachi 50EX12BA?


The Hitache 50EX12BA uses 2 IC's labeled STK392-110. If you are looking in the back of the set, the convergence IC's are mounted on the large heat sink on the right side. If one of the IC's has burned out, go ahead and replace both IC's with the newer improved STK392-150 IC's. These IC's are very common and can be ordered from almost any electronics parts supplier. When installing the new IC's you will need to clean off the old heat sink compound and apply fresh compound to the back of both IC's.
