Question about Televison & Video
I Have PANASONIC TV Model PT-47WX42F Serial MX21990017
My Problem Is That see a Double vision About 1 Inch Green
IT SOUNDS like a convergence problem; go into the customer menu and select convergence--you will first be offered a green cross--do not adjust it--go to red or blue and look to see if either does not move in some direction--for example red will move up and down but not left or right.
If you find this--you have a bad convergence chip---this set uses 2 STK-392-110 chips; both and any bad resistors that protect them need to be replaced and the set adjusted.
You can buy both chips on Ebay for about 12 dollars plus shipping; the chips are located on two metal heat sinks and are black(2 1/2 inch wide and 1 1/2 inches tall--the STK number will be printed on them in white). The resistors are in front of both chips and are light powder blue in color---any of them that are white in the middle are gone--the ones you want to look at are marked 2.2 ohms.
If you are able to do this repair yourself I have step by step from start to finish instructions I have prepared in Microsoft word--if you need them email me and I will send them to you.
If you are not able to do this repair look for someone in your area--many shops charge 300-400 for this repair. If they say it "has to go to the shop" keep looking--any good tech can do this repair in your home in about a hour--I know as I do hundreds of them each year for about 200-250 total depending on model of the set.
Now is the slow time of year for TV repair shops--shop around---200-250 is a good investment and you cannot replace the set for this kind of money---also this is about the only real problem most of these sets ever have---once the chips are replaced the set should be good to go for 5 years or more before it has this kind of trouble again.
