Need help troubleshooting convergence issues on this set.  Have
replaced both STK 392-110.  Replacing the stk's seem to have not had
any effect.  I've checked all of the resistors near them and haven't

I would appreciate _any_ laptop smart battery connector pinouts
for inclusion in a little database I hope to build; the important

My 6-year old Sony WEGA, 27" tube TV, model KV-27FS13 just started
turning on and off when you walk in front of it at 0-1 ft.  It's
