Took to repair shop, tech said after two days of troubleshooting, he took signal board out of 2nd TV
and put in mine, and the picture was great. Claims components cannot be replaced on the signal board and will contact Panasonic for price of new signal board on Monday. Also said there is a place in Ohio that rebuilds Panasonic boards which may be cheaper. Any comments or sources of signal boards?
Dont know if youre still looking for a signal board or not but this site has one. I hae used this site numerous times their products are great and prices cheap.

Return The board and your money will promptly be refunded. One of the new guys in the wharehouse used the wrap that is for screen assemblies on your board by mistake, but as I told you earlier just return the board your money will be refunded and we will rebuild our board. We have helped literally hundreds of people with our patys and services and we would like to honor our committment to you as well.

"This site" turns out to be Slinteriors' site. He shipped me a dead board in high-static bubble wrap.
On my original board, I found if I used component cooler spray on the front convergence chip, the picture would look good for a second or two then go back to the lines across the screen. I pulled the signal board and resoldered the convergence chips, and the lines across the screen are consistant now (before, they started far apart, and got closer and closer as the set warms up. When prob first started, after five minutes warmup the picture was good.)
I ordered new convergence chips and changed both, The picture is slightly better, still has lines, but after 30 to 40 minutes, the set shuts off with the three blinks of the front panel red light, indicating convergence circuit problems. Should I replace the resistors, or ?? By the way, after resoldering the convergence chips the first time, the circuit cooler spray had no effect on the picture.
