Question about Televison & Video
My Phillips big screen tv model 60PP9209/17F. I can't adjust convergence crosshairs. when I turn on my t.v the picture is not clear double image after 30min to an hour it clears up. but when I turn off t.v and turn it on it starts all over again
I have seen this before--This set uses 2 convergence chips--usually they are STK-392-120 CHIPS--sometimes they will be flaky when cold--both chips need to be replaced and the set adjusted.
You can buy both chips on Ebay with shipping for less than 20 dollars. The chips are located on (usually) two metal heat sinks side by side and are about 2 1/2 inches wide and 1 1/2 inches tall---they will be black and have the STK number printed on them in white. If you open the set and locate them confirm the number that is printed on them.
Sooner or later if you keep using the set this way it will damage other parts around the chips.
MOST shops charge 300-400 for this kind of repair; I have done hundreds of these sets here for about 200-250 including parts, labor, house call.
If you cannot do the repair yourself look for someone in your area to do it--takes about an hour and any good tech can do it right in your house.
Make sure whoever you get to do it changes BOTH CHIPS--if not you will soon have the same kind of trouble again.
If you have any questions or need help reply to this post here.
I do this here for free so if this has helped you take a minute to give me a vote here.
Usually in this situation--just the 2 chips need to be replaced and the set adjusted!
