No sound Several weeks ago, the sound stopped working on the lower numbered channels. Over the past few weeks, the sound has stopped working on all channels. The picture is perfect. The TV is hooked up to basic cable (no cable box). I've checked all the settings and everything looks in order. Could this be a cable problem? Thank you,

the problem is your using a toshiba. I bought one several yrs ago and in just a few yrs things stopped working. first the sound wuit, then usb ports stopped working then when booting up the laptop it asked for a non existant password. finally i just tossed it out

Sounds like a problem with rear brakes.If this vehical has drum style brakes if the brake shoe has become disconnected in some way it will usally wedge against drum in one direction or another.You need to inspect rear brakes.

check sound system on that 3 channels

sounds like the fuel filter.. if you have those kind of skills, they're usually cheap to buy and worth a shot to change. depending on the location the labor will take you 1 - 5 hrs...

sould be wiper moter is failing or plastic clips are wearing out.

Make sure the SAP feature is turn off in the TV.

We have a hd2560 (bot 10/04), french door with inside water dispenser and it had stopped working a year ago, but started working a few months later. I couldn't figure out what happened, but suspected the water line was frozen. I later found out that the water reservoir is located behind the fruit and vegetable bins, so look there to see if the water is frozen.

Two weeks ago, our frig/compressor stopped cooling after making humming/clicking sounds for weeks. Fortunately, Maytag has a 5 yr parts & labor warranty on the compressor, so we were covered. Evidently, there are quite a few faulty compressors out there.

I believe that the compressor had been over-cooling in the past and caused the water lines/tank to freeze. This would also cause frozen produce/fruit. I would immediately contact Maytag/Whirlpool if you suspect a faulty compressor as well.

I had the same behavior, but not as a result of power outage. The TV is driven by windows CE software and it goes haywire every now and then. Usually pulling the plug for a few seconds takes care of any problems, but not this time (as you noticed). I had unplugged my ethernet connection on the TV a few weeks ago and thought I'd hook it up again to see if there was a new software release (not likely). I went to the menu and chose "Connections" and then chose "Ethernet Setup" and then chose "Reset All". After I closed the menu the TV rebooted itself (as it said it would). After my TV rebooted I had my analog channels back. There shouldn't be any connection between these two events, but it worked for me. Hopefully it will work for you as well. Good Luck!

Practice visual acuity technique! Look for bad solder connects==none found?? suspect flyback xformer.
