Samsung LE32N73BD screen problem

[daroo]

Hi, I have this tv Samsung with a problem. The screen shows some flickering stripes while watching tv. When there isn't any imput or when you press some buttons on the remote (to change input or volume) there is also other points and lines on the center of the screen.

I replaced two caps on the power board that looked bad but didn't solve the problem

Hope the pics will explain better than my bad english

how can i save this tv from the junkyard?

Maybe you can remove cover from mainboard and get good picture of it

All your voltages are stable? Might want to make sure white connectors between boards for cracked joints.

voltages looks good, tried a reflow of the mainboard but nothing changed, still the same problem...

Tried also "shaking" the cables while the tv is on to see if the problem is some connection but the problem is always there...

Re: Samsung LE32N73BD screen problem

is there something I can try to fix the mainboard, or to test it?
I searched in the forum and it seems that no one has this problem..

Looks to me as more of a 'logic' failure. T-CON / Mainboard problem...
Could be hard to nail this on component level.
