Re: Help need service mode

The vertical height problem can only come from the electrolytic capacitors around the vertical circuit .You have to change all of them !.Also i commun to the vertial IC to get damaged because of the capacitors that i mentionned .So baciaclly change it too. You want to star to trace back the power supply line for the vertical IC .Is powered by the flyback .Most of the times there is a small value resistor .When the IC goes into short circuit this resistor also gets open .So check it too
.If you don't have a total collapse of the vertical .Then the problem are just th capacitors as i indicated .The vertical circuit is about to go into short circuit .To prevent it ,just replace those capacitors i said!

regards
