I recently turned on my Samsung LN-S2341W to play some N64 when the picture came up in black and white. I checked the RCA cables at the back, and they were connected correctly. I tried 3 different cables, thinking the cables where the problem, but the problem persisted. I tried 3 different game systems (Gamecube, PS2, SNES) and all came out in black and white. When I turned on my Direct TV box to see if the regular TV channels were working, they came out in black and white too! I've tried everything in the menu to try to fix this but nothing works. Please help!

I have a Samsung HP5053 Plasma Flat Screen and there was a cracking noise and the picture clarity changed to dull. Does anyone else have information on recalls for this TV?

make sure that the plug on ps2 is connected and check the settings on tv and the settings on ps2 browser are correct if possible check ps2 on another tv to be sure of it's settings if the ps2 works the check channel setting on tv make sure it's not in pal setting it should be ntsc and also check the antenna setting make sure it might be set to cable and also check cables of any sharp kinks your problem is with the yellow cable red and white is the sound

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

My Mom's LNR408D also had sound but no picture. I was able to fix it by soldering in a jumper wire across a blown (1.5A ???) SMD picofuse on the "T-Con" board.
Consider attempting this ONLY if you:
0) Know enough to avoid the potentially fatal High Voltage parts of the power supply board!!!
1) Are a fearless hackazoid
2) know what you're doing with a soldering iron and teensie SMD parts
3) are gonna throw the busted thing out anyway so you have nothing to lose and won't be sad if you screw something up.
4) Know enough to avoid the potentially FATAL High Voltage parts of the power supply board!!!!!
This board is at the top center under a close fitting RF shield. The suspect part was labeled "CP" on the board and marked with "P" on the part. It is visible above the right-center of the connector from the main board. An ohmmeter showed it as open, so I bypassed it with a jumper wire from connector VIN to the hot side of C13. One image shows the suspect part and the jumper in place.
The other shows the TCON board placement top-center (under its RF shield). With care, it seems possible to test the fuse and put the jumper in place without removing the shield. (Obviously don't touch anything else with the VOM leads!)
Thanks to ZORBUS and Steve's TV and Electronics for the idea.

have you tried to umplugging the tv and let it sit for a little while. I would unplug the tv like before you go to bed and plug it back in in the morning and try it
Testimonial: "Well, I unplugged it for several minutes, and that was enough... thank you very much!"
