Ur tv still have dead resistors parts,test all 12 resistors parts around the 2 STK convergence ICS and changes some more dead resistors parts or changes all 12 resistors parts for sure.If tv still have the same problems after tested and replaces more resistors parts or all 12 resistors parts.Than some how when u handling and replacing the 2 STK convergence ICS and resoldering the 2 STK covergence ICS u short it out the 2 STK convergence ICS by resoldering without proper grounding ur self not to allow for static electricity to kill the 2 STK convergence ICS or u using a soldering iron to high of a wattage for doing soldering ICS work.

I have a panasonic PT-47wxc43 projection tv. I have green and purple halos coming up from the bottom. The screen has purple and green double images which are worse from the bottom up.


Hi,
This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

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.

Convergence IC replacement


No as long as the STK number is the same they will work. Just be careful where you get the parts as alot of places online sell cheap chinnesse made ICs and they wont last. I usually get mine at the following link, and I havent had any trouble with their ICs.

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.
