SAMSUNG-SP-43T6HC PROJECTION TV

[alish]

Hi to all !
this projection tv came to me with bad convergence . I replaced 2 STK 392-040 & resistors .  I had to adjust the convergence. Everything is fine except for one thing .there is network interference on screen.
Even without  video. Does anyone know the problem is ?
thanks in advance

Hi

Was the interference present before you changed the STK's? There are lots of cheap STK's about but are below spec and cause problems or fail within a few weeks.
