Entertainment Center: TVs, Stereos, VCRs and DVDs - Panasonic 36" pic pulling inward from R corners

On right upper and lower corners, picture pulls inward (along top and bottom, reveling black edge, about 1-1 1/2" The Brighter the picture at the time, the less the inward pull, but never completely eliminated. The end result is a convex curve on screen right. Any ideas???

If this model has a pincushion adjustment potentiometer, it is a simple fix. Otherwise, you need to get into the service menu to correct the problem and I do not recommend that a novice be accessing the service menu unless they know what they are doing.

Took off the back, the only potentiometer control I can see are the tabbed ring on the neck of the tube. No sure if I should mess with them...have been covered (locked) with poured plastic. Think this is a service job?

If there was a pincushion adjust, it would be on a separate board mounted vertically on the main board. DO NOT mess with the rings on the neck of the CRT. Those are the convergence and purity magnets. Help your local economy and throw some business your local TV repairpersons way.

Something wrong with the pincushion circuit. Could be a busted voltage reference due to cracked solder joint/rework or some leaky caps. Check for what appears to be dried soft drink stains on the pcb. It helps to have the usual dust in there so you can see the evidence :)

To check for busted solder joints, get a wood stick like a chopstick or paint stirrer (so you don't kill yourself if you touch the wrong thing) and gently press on the low voltage components one at a time while watching the picture. If the picture fixes itself, you've found your problem.
