Are the dots syncronized, i.e: in slanted vertical bars or random? What type of main board and power supply?

Hi Willyam,
If the dots run from side to side in near vertical bars, or do they appear anywhere on the screen. If first condition maybe interference from the power supply or inverter, otherwise maybe T-Con or main board. Can you pic the fault too.

Looks like Vestel ¿? make notes of the boards, also if you are using mobile  for pics use a magnifying lense can get good results, your pics are a bit out of focus.

H Frank,

Guess Willyam 1 needs a mobile phone like yours - doesn't look Vestel to me - Chris.

Hi Chris, Willyam1
No, not vestel ¿?, put up some details of the boards, nothing like the good old tube days.
