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.

Please seeking help on how Ican get IC NUMBER LA 4645 FOR RADIO PANASONIC RX-DT 707 COBRA.


A vendor I frequently use is Encompass. They list the part here. You might try contacting them and find out if they actually can get the IC. It says there are none in stock, a special order item, but say 6 day ship time after you buy it.

I haven't been able to locate a replacement part number for the LA4645. Seems that there is no exact replacement by another manufacturer.

Good luck with your repair!

Panasonic PT-56TW53 56 in. Rear Projection Television- won't turn on -flashes 3 red lights- what's up? Turns on for a second, then it turns off and red light flashes 3 times... I've seen several other...


Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part numberAA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck

Convergence


Next to the ICs you will see about 6 or 7 resistors with no color bands usually green in panasonic they all look identical. Check them with a ohms meter to see if any are open. The ICs usually take out one or two of these resistors when they go out.

Convergence adjustments


did you use the proper STK IC's Do the replacement IC's have SANYO on the face of them? If they do not, this could be your problem. You must use the IC that the manufacturer recommends. All IC's are not alike. Go to MCM electronics and enter your IC number and they sell original SANYO IC's. Good Luck
