Question about Toshiba 42H81 42" Rear Projection Television
No picture power lite flashing when plugged in. at first vertical hold wavy then warm up and picture would stablize
You are probably having 2 problems. on that model there was a jumper wire the fed the convergence amps power and would get very bad cracked solder. and casue some fuses to open on the main deflection board. if that is there i would recomend replacing the 2 convergence amps(stk392-110) and open fuses. but your wavy lines are going to be all the 10mf16v surface mount capacitors inside the hyperunit(figital scan card) it is a square metal case located behind the input board.*****it is soldering in with 4 tabs on the bottom side of the signal board so be careful not to just start pulling on it to get it out*****
