Question about Televison & Video
Hello, I read an awnser you posted 2 years back or so about how you thought that maybe a power sorce had a bad conection. Did you mean the high power out put or the regular transformer from 120 down to system voltage? My screen got dark and i have to crank the brightness all the way up to get some picture out of it. It's a little fuzzy but clear. Thanks for your responce.

You are losing screen voltage or whats called the boast voltage most likely. This is probably being caused by a bad capacitor in the sweep power supply. You will need to get a service manual as well as use an ESR type capacitor meter to find the bad capacitor(s). Good Luck

First off I think you meant Panasonic PT-51G44A which is an AP815 chassis. That unit has an all to common failure of the capacitor at C581 on the D board which is a 33uf/160v cap. Replace it and I think that will solve the problem..

SOURCE: picture fuzzy on dark scenes
hey all...just to let you know, I had noticed a post that said the individual prior to getting or ordering new parts, he took the tv apart from the back, and cleaned.
My husband spent the better part of the day, vacuuming out and blow drying on cool all the dust and such. after doing this the picture was worse, HOWEVER, we noticed the flashing was gone. SO, he took it apart again, and this time, very carefully took apart the compartment holding the color wheel. He took out the lens, cleaned it with a lens cleaner cloth. Took out the color wheel, very carefully cleaned the wheel, cleaned out the whole inside of that compartment, put it back together, and VOILA!!!!!!
BRAND NEW PICTURE EVEN BETTER THEN WHEN WE GOT IT.... no lies, no problems, it was extremely time consuming, but I ccan't describe the difference.....UNBELIEVEABLE and no spending a grand on a part.
Don't hold me responsible for any problems, but this just worked for us, and my tv is NO LONGER FLICKERING,, NO MORE LAVA LOOKING COLORS, NO SHADOWS.
JUST CRISP! WOO HOO, I DONT HAVE TO BUY A NEW TV... yet.
