I'm having this problem with my TV:


from searching the forums it looks like the likely cause is failing capacitors? Anything else it could be? Could anyone suggest the likeliest capacitors to be causing this and where to look for them. Thanks for the help.

Most likely (in no particular order):
C4E4 100ufd/35V, C4E5 220ufd/35V, C4E2 100ufd/35V, LA7838 IC

agreed, with JTS.
That's called vertical foldover.

thanks for the help, those parts are all dirt cheap fortunately. Is there any possibility it has damaged the screen being operated in this condition for several months?

Unlikely. Wink
Now "No vertical sweep" at all for several...that's another story.

Success, my TV is back to normal, thank you.
Fry's stocks that IC, when I started digging into it there was another capacitor that was clearly bad, a 100uF/50V (forgot to note the ID) anyone making this same repair will want to have that cap as well. Thanks again.
