Question about Toshiba 37LX96 37 in. LCD TV/DVD Combo
I have a Toshiba 37LX96 that I bought new early in 2007. I have never had any problems until Saturday afternoon. Suddenly the TV went dead...no sound..no picture. The only sign of life was the yellow blinking light on the front where it says disc. I checked the owner's manual and it states this is normal for this to occur because it was rebooting this is not a sign of malfunction and would only take a few seconds. About 3 hours later, I decided to do a hard reset and unplugged the TV for at least 12 hours. The next morning I plugged the TV back in and the reboot started again. It has been almost a day and it is still rebooting. Please can you give me some guidance as to what the problem may be.
I don't know if you guys are still looking for an answer but turn the TV on where you can here that something is actually playing on the TV then grab a flashlight and turn all the lights off. Get real close to the screen and shine the flashlight on the screen. Can you see something on the screen? If you can then there is a very good chance that one of the inverter boards are out. This could be the slave or the master. For the 47" I actually have the same issue and have ordered the master inverter board. For the 42" I have both the master and the slave board and they are both working. So for the person that has that issue on the 42" TV if you want a board for your TV email me at email@example.com. For the one with the 47" flip a coin and order an inverter board for it either master or slave and try it. To determine which inverter board it is you would have to take the DC voltage across the start and then the end to see if you are getting any power. I hope this helps. By the way inverter boards usually run between 60-120 dollars each and the slave board on both these TV's are easy to install. The master is a little harder due to the power button board is in front of it and has to be removed first. Let me know if this helped.

Here's how I fixed mine...
Look inside the back of the TV just above the power cord - there are two small LEDs, one green and one yellow (no need to open the case - you can see them through the cooling slots). In my case, the green LED would light for a few moments after plugging the TV in, then the yellow one would light and stay lit.
Go to the Toshiba site and download the latest firmware upgrade.
Copy the firmward upgrade to a SD memory card using your PC (SDHC cards larger than 2GB don't appear to be supported by the TV, so use a smaller one). I copied *both* the zip file as downloaded from Toshiba, and the contents of the zip file. That is, I expanded the zip file and copied the contents to the SD card as well.
There's a metal cover over the SD card slot on the back of the TV. Remove it (a single screw)...at one point, Toshiba has directions on the firmware download web site.
Unplug the TV and insert the SD card. Plug in the TV again, and in my case, those little LEDs stayed green. I saw none of the instructions on the TV screen - rather I just let it sit for about 10 minutes, then I unplugged the TV, removed the SD card, and plugged the TV in again. Viola - the TV works.
I'm thinking perhaps Toshiba uses a type of memory that requires battery backup, and if the TV is unplugged for an extended period of time, it's necessary to re-flash it.

I had the usual problem with a Toshiba 32HL67. Shortly after the warranty period ended, the TV would not turn on. The yellow light would blink three times ad infinitum until I unplugged the TV. After those incidents, the TV worked fine for about a year. Several weeks ago, the same problem started again.
Took the TV to a local repairman and discussed it with him. His thoughts were that it either involved the digital video board or the power supply. He suggested that I find the video board on the internet and let him install that. I located this part at discount-merchant.com for $49.95 plus shipping. Received it last week and had him install it. TV has worked fine since then. Got my fingers crossed.
The video board is Part V28A000320A1.
