Have a toshiba 37av502r as the television on an att cable. all has been working well until my grand-daughter was watching it one afternoon and used the tv's remote instead of the cable remote. Now the video and all other functions work but there is no volume. getting the correct indications from the network box and the tv but still looking at a silent screen. Is there a setting you can point to on the tv which might be set wrong or can the tv be reset to factory settings?

Toshiba 37AV502R When tv is on it sometimes turns itself off then on then off then on until I click it off with the remote or unplug it. Tried cooling capacitors Tried turning off for a day No luck.

The power supply or the backlight inverter is faulty. First of all replace all the electrolytic capacitors in the power supply board.
If you wish to get some more details check the bellow added link.

Wont turn on

total dead then first look for the fuse inside to be bad, if a standby light comes on but set will not power up, look at the power board for damaged parts including puffy filter caps.

My toshiba tv 37inch 37av502r the tv went off but the power light is still blinking but no picture comes on

It may be in the safety shutdown due to shorted circuits or failed power supply due to bad caps.
It will require in-depth troubleshooting. Please read my guides first.

I have just got a Toshiba 37AV502R flat screen tv. I want to connect the digital audio output (optical) to my older 5.1 speaker system. The input on the sub woofer is a 15 pin VGA... I can't seem to find a...

Is this sub a Bose. The only reason you would see a VGA type connector on a sub is if it is dedicated to somthing else such as Bose 3-2-1 system. This is not a standard VGA input and can only be connected the the dedicated head unit. I need more info on the sub. Brand and model. Ther should be an analog audio input on the sub. This will be sufficient.
