Took the cover off...found two caps swelling...would this be the reason for the red and green dots all over the screen

Re: Samsung Distorted Screen

They would need to be replaced whether they are or not and they are cheap enough. Replace with high temperature, low ESR capacitors.
I would also check all the solder joints on the board and make sure they are good.

If you run with two threads on this it will be confusing.

Re: Samsung Distorted Screen

Ok sounds good. Do you believe all the dots could be caused by the capacitors swelling?

Clean all that dust off, too. That looks like X-Board issue to me. That's the board on the right side looking from the back.

Re: Samsung Distorted Screen

Yes I have taken care of the dust now. I have two caps swollen (not on the X Board). I am going to replace the caps and then look into the X board. Anything in particular on the x that I should be looking for?

Re: Samsung Distorted Screen

Basically cold solder joints, and measure the ESR on the e-caps on the X-Main and Y-main Bds. Measure the Vs, Va Ve, Vsc and Vy voltages and make sure they are in line with the voltages on the label.

I have found "working" X boards on Ebay really cheap. Y boards, not so much. I may just order an X board and go from there. I have been picking up so much time at work it is becoming hard to get to what I need to do at home. I have found a few x boards under $20, so that wont be much of a loss if that doesn't fix the issue.

Re: Samsung Distorted Screen

Well, replaced the caps and screen is still jacked. May have to just order an x board anyway...

[fire84rescue]

Re: Samsung Distorted Screen

Well, I replaced the X board and the green and Red snowy screen is still there!!! Does anyone have any idea what it could be still?

Re: Samsung Distorted Screen

Looks like this one is going in the trash! Anyone need any parts before hand?!? I haven't had luck fixing it so bye bye!

Re: Samsung Distorted Screen

Ok this is an LCD tv. Does not use an x board. X board is in a plasma tv. This honestly looks like an issue withh the eeprom on the mainboard.

Mute 1-8-2 power. Do this on thhe remote with the tv off. Look in service menu for lvds settings. Possibly someone got into menus and messed with it? Lvds bit rate possibly.

Btw I see your in Deleware. Did you feel that earthquake?

Re: Samsung Distorted Screen

Oh stupid me .lol I thought it said LNT.
For.some reason I'm not able to view pictures lately.

But I would suspect something going on with y sustain. Have you measured all voltages yet? What's your VSCAN reading?

Nope, I didn't feel the earthquake. I am southern Delaware almost to Ocean City Md. I know several people who did though.
