If it, or your receiver has a headphone jack, search on the web for "wireless headphones for tv", or visit Best But or a local electronic shop.

Toshiba Tv won't turn on


if the power light doesnt come on chances are a shorted component on the power supply has blown the fuse. If so replacing the fuse will most likley only result in the fuse blowing again. Replacing the power supply would be the best bet. You can get one from www.tvcircuitboards.com

No power


Hello, If the battery won't charge and the laptop won't turn on but the ac adapter works with other laptops, then the problem is the port where you plugin the ac adapter. Some of the laptops has it built in to the motherboard. So you might need to have it repaired by a technician. Or if the laptop is still in warranty, you might need to send it to the manufacturer to have it repaired or replaced. But if the laptop works without the battery, or it will turn on but the battery indicator is not lighting up, you're facing one of these problems. 1. The battery itself is dead. 2. the battery bay is loose 3. the battery itself is loose Hope this helps

Fixed with a firmware update (hard to believe, but true). Search Google for a file named: 2007SEN069.zip (don't worry if the page you find it on doesn't mention the 37HL17 - it worked fine). Unzip the file, and copy the 3 folders and 3 files to the root of a small SD card. The SD card MUST be 2GB or less in size (I used a 1GB card), and it MUST be formatted with FAT-16 (not FAT-32). Mine was pre-formatted as FAT (FAT-16). The SD port is on the back of the TV behind a cover plate near the power cable. You do NOT need to remove the back cover of the TV, just the small cover plate (1 screw). UNPLUG the TV; remove the cover plate; insert the SD card (prepped as explained above); Plug in the TV; Watch the yellow lights blink, then turn blue, then go dark; UNPLUG the TV; remove the SD Card and replace the cover; Plug in the TV; Yellow lights will blink a few times (this is normal); when blinking stops, turn on the TV and you should be good to go. :-)
Pictures attached are from a Toshiba software upgrade bulletin I found online.

Toshiba 32AV502R won't turn on even though green light goes on


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Toshiba Tecra A7 Won't Turn On


You may trying pulling the battery out while its unplugged. Another issue may be the socket where the AC adapter plugs into the laptop. Is it loose, broken prong inside the socket. It should have been able to power up at least for a brief moment just on the battery. Hope this helps ya.

Toshiba A135-S4527 starts to power up then shuts down.


When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a small brush and can of compressed airto do this.

Hi.

Take out the AC power jack and then remove the laptop battery. Plug AC power back in and see if the laptop will turn on. If it turns on let it boot the operating system and then shut down as normal, remove the power cord and reinsert the battery and again see if it will switch on. If it does then there has been a glitch with the battery. If it doesn't then there is a problem with the battery.

If the laptop won't switch on either with or without the battery then there is a possibility that the motherboard has developed a problem.


Good luck.
