Question about Panasonic PT-53WX53 53" Rear Projection HDTV-Ready Television
I've owned this TV since new.
Now when I turn it on I get light wavy lines along the top 1/4 of the screen for about 5-10 minutes then all is clear and the picture looks fine.
Any recommendations for the fix of this problem.
Thanks ahead for any suggestions.
Each component on the board, cap, diode, transistor, etc has a location number prefixed by an identifier, thus c2451 is "c" a cap located at 2451, d2050 would be a diode at 2050 and if you look at the board closely you'll see these loaction numbers are grouped by their circuit. All of the 7xxx will be with a lined area no larger than the circuit they support. A schematic, unless you're a wiz at reading them, won't do you much good because they are drawn by circuit not postion.
Get a good pair of reading glasses and a good flashlight.
Hope this helps!

That unit has a history of bad caps throughout the convergence and other circuits. Personally I believe it was an error in the design.... Check and/or replace the following::: C2451, C3007, C7022, C4613, C2507, C7060 all 100uf/16v and C7127, C7128, C7103, C7154, C7136, C3010, C3008, C3002 all 47uf/16v... You can use a higher voltage rated caps such as 35v or 50v for greater reliability.
