Hi Janet . . . You need a much more technical person than I am. Ours hasn't given us any problems. Toshiba tech support would be my first stop. Good luck.

I use my remote. But the buttons are on the left side when your facing the T.V. if that doesn't work then it's defective.

I'd just back up in the "Menu Tree" and try again. If that didn't work I'd Power cycle the unit to reboot it and start over. Good luck.

I don't really know; my Toshiba died after a little over a year, not able to be repaired, tossed it.

My set never had the picture issue prior to the issue of the tv switching off entirely and not coming back on. I tried the side power buttons, and I also called Toshiba customer support whom walked me through holding down the power button and unplugging the tv for a while, etc. They were unable to help, so they directed me to my local repair shop. Called them, they seemed helpful, were supposed to order a new power supply for the TV. Haven't heard back from them...but after leaving the tv unplugged for a day or two, I plugged it back in and its worked ever since like a charm...have no idea what the problem was, but it works now...just hope it stays this way.

Mine has booted fine since purchase. Sounds like a power supply problem. Can you check to see if you have a voltage or on/off switch to the power pack on the rear of the pc and/or try a new power cord or surge protector? I don't know the warranty period, but it should be easily determined by looking at your amazon order history and reviewing the write up for this particular purchase.

There should be a small hole on the back ov the unit. For some reason the unit has frozen up. Use an unfold paper clip to trigger the manual reset. That's all I can suggest other than return it where you got it for refund!

Is there a disk stuck in it? Try unplugging it for a moment and plug back in.

Try a "battery re-boot:' Shut down the PC, unplug it, remove the battery, plug in the laptop, boot up, shut it down again, unplug it, insert the battery, plug it in, and reboot. I'm not sure what operating system you're using, but to be safe, generate a restore point.

try disconnecting the power, remove the battery , then replace the battery and the power , restart and if it does start call dell and have them remotely check out your laptop

Try taking the battery out while plugged in and turned off. Turn it on without the battery installed. If it does not work the computer has a power supply problem most likely. I have replaced my power supply twice and my battery four times in 6 years.

Every so often you will have to replace the ballast unit on a Toshiba (I had to do it twice). It's a pretty straightforward repair that does not involve the light engine. It's a high voltage supply unit that powers the lamp. When it fails, it seem like the lamp fails and gives you the same front panel indications. On the second ballast failure I also had a small fuse fail that was on the opposite side of the TV near the wire entrance but deep inside where you can barely see it let alone pop it out. I did it, however, and you should be able to as well with a little help from youtube.

Help! Same problem. Ours worked for less than 24 hours and will not turn on at all, no light, nothing. It doesn't even almost come on. Blank. Screen. Frustrated!!

I've had this problem many times with my Toshiba, when the battery runs all the way down or changing the battery you have to restart and go into the bios, when in there, load default settings, then restart and it should be charging again

Unplug the TV for at least 3 min. Then hold the power switch on the tv it will be blinking and hold until it stopped blinking which is on. It should work. If this does not work you may have to get a service man as it may need a new mother board. Good luck.

Press the SRC button to turn it on. If it does not work, it might be bad wiring or problem on the product itself. There is not many reasons that might cause it to go bad

I don't know. My laptop was defective and I'm in the prosess to get it fix under Toshibas warranty.
