57" Toshiba with wavy green/red lines "good overall picture"
Appears to be a convergence problem,
the chips are located on large aluminum
heat sinks. Check near the 2 or 3, STK IC's for
+ and - voltage usually 20 to 25vdc.
If 1 or both are missing, check microfuses.
They should both be close to equal in
voltage reading, if not, turn set off after it has been on for 10 minutes, feel the heat sinks at each IC,if one is hotter than the other,
replace both IC's or all 3 if it has them.
Now check the small low ohmage resisters in
and around the STK IC's and you will most likely find a few burnt or discolored and have
changed in value, replace these or the new chips installed will self destruct.
