Samsung Solarized Distorted Picture since yesterday , Dont know which hardware part needs to be changed tried reset all cables and board cleaning but no luck , I upload a video on youtube hope this he

SOURCE: sound no picture, which component is tcon board? where all audio/video/cable/hdmi plug in to?

I have LNS4692D. Returned from vacation, turned tv on - no picture. Tried turning tv off for 4 hours- nothing. Symptoms are: tv is on - no picture , just sound; menu doesn't show, volume bar doesn't show;E.Saving is working - the backlight is changing from lighter to darker.
Found this website and ordered T-con, otherwise known as the LCD panel driver board, p/n# Bn8101286a ( thanks premtech) from partstore.com for $124. Part number BN81-01286A A/S T-CON Board.
Installation:
1.Remove plastic cover. There is an arrow for each screw that needs to be removed. Make sure to unscrew pins next to VGA port. I've spent some time trying to figure out what else is holding the plastic panel until I found this pins.
2. Remove big metal shield in the middle of tv that is covering main components. This shield is being held by small black screws all around it.
At this point you will see cover of T-CON. Here is the picture

3.Remove metal panel that holds main components. Locate big chrome screws that have arrows pointing to them and unscrew them. Remove 2 more screws on the bottom of the panel that holds it together with a box for cables. At this point the main panel will be lose
4. Carefully start lifting the panel. You will see that there are connectors going from components on the panel to components on the lower panel and T-CON. Carefully unplug these components and raise the main panel.
5. Remove 4 screws that holds T-CON cover. Pull the cover so that T-CON is completely exposed. The cover is connected by thin alluminum , don't hesitate to pull it , but don't rip it out.
6. Once T-CON is exposed you will see 2 red ribbons. I've spent some time to figure out how unplug those from old T-CON board. Here is the suggestion. Don't try to pull it out. All you need to do is to lift small plastic lever that is part of a connector. Then ribbon can be slided out. If not sure what to do, see how this is done on the new T-CON. It has a principle of buckle on airplain safety belts.
7. Remove old T-CON and install new you.
8. Follow reverse order.

I've never fixed TV before , but this was totally successful project.

SOURCE: Samsung LCD tv - Turns on and off by itself.

Not sure if this is the same problem, but I just moved and set up my Samsung 40" LCD and it has been going off and on by itself with the worst yesterday every 2-3 minutes. After speaking with a friend of mine who is not in the Tv business but just has good common sense, I determined it was likely a bad power strip. The bottom line is I replaced the crappy power strip (which was fully loaded with all 6 outlets in use) with the higher quality one I had in the other room. The problem is gone. I suspect the power strip was failing or real bad quality........try plugging the tv directly into the wall outlet first. hope this helped.

It's not the x main. 90% of the time it's a y buffer that goes out. It's usually the top buffer. 3/4 of the time the buffer takes out the y main board too. You cannot just replace the y-main or buffer because it will just burn out the other within seconds. Also about 1/4 of the time it'll take out the top transformer on the power supply too. The solution? First disconnect the power to the y main board. turn on the television and check the voltages coming off of it. Careful it's high voltage 208V! Remember it's DC too. Then disconnect the buffers from the y main board. You can try powering the y-main up to see if the little LED lights up. This does not indicate it's working though but it'll tell you if it is possible to fix. The fixes for these boards is only for electronics guys. It usually involves replacing 1-3 capacitors and 1-4 FET's. Since a bad buffer can take out a good y main in seconds it's usually recommended that one replace all 3 boards at the same time. It's a $250 fix. How do I know all this? I've now repaired 5 of these televisions. I owned one and spent close to 600 repairing it. I bought misc parts and broken sets online for months before I had 2 different repair guys walk me through the process of repairing them. I had so much cash tied up in parts that I bought 3 more dead sets and repaired them to justify all my spending. I've never had an x board fail. I've had EVERY top buffer fail. I've had all but 1 y-mains fail. and 1 lower buffer fail. I've also had the y buffer fry it's top chip, blow a capacitor and FET on the y-main, and fry the top transformer on the power supply before my eyes. It only took 5 seconds. Replacement of the 3 y boards will almost always fix the sound but no picture problem. Hope this helps!
