Question about Dell W4200 42 in. HD-Ready Plasma Television
This problem began out of nowhere. I went to turn my TV of with the remote, and it didn't respond. Then, I went to the TV switch manually and it took 3 to 4 seconds for it to turn off. I then turned the TV back on, and the remote worked for about a minute, then the same problem occured. None of the buttons on the control panel wanted to work. I couldn't adjust volume or anything. I just don't get it, Dell products suck!
I have this exact problem with same TV. Did factory reset but that didn't fix it. Any other suggestions?

SOURCE: OSD menu locked
When the OSD is locked, pressing the menu button again and it will take user to OSD LOCK menu. Press (+) to unlock and allow user access to all applicable settings.

without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.

I had the same problem with my tv.No sound! I finally figured it out. It was the speaker wires! Once I changed them to a slightly stronger speaker wire, it worked great! I have sound to my tv and I haven't had any problems since then.
