Grey border down sides of picture while on AV1

Assuming it's not your device causing the grey lines, just change your aspect ratio settings. Each input has a different set of settings that you can change, so don't worry about messing up the settings on your HMDI 1 input for example if you change your AV1.

TOSHIBA 32bv500b screen stops working sound works fine

I'm having a hard time finding any parts for the set besides the power supply board. The T-Con is usually located top center on the back of the LCD panel. It will be under a metal cover. Sometimes, the t-con circuitry is built onto the main board. If this is the case with yours, you will have to order the main board. Feel free to send me a pic of the back of your set.

Why does a grey screen and no picture appear when i turn on the tv??

You haven't given the exact model number to your Hisense TV here, so I assumes that your TV is a picture tube based one, and posts this solution. Your TV has some bad solderings at the video-IF section. Normally all TVs nowadays, this section will be composed with an integrated circuit [IC]. If you have skill in soldering techniqe, just open your TV, and resolder all the solder points of the main IC, which will be a large one, without making any solder bridge short in between adjecent solder terminals. The IC will heat up to an extent, and repeated heating and cooling may make solder terminals to get loose contacted. This is a common problem to almost all TVs irepective to which brand or model it will be.
The problem to your tV now, is with some loose solder terminals itself. OK.

Black screen/No TV Guide

Mine is doing the same thing. It's under warrenty and a guy is coming to look at it today. I will post more info once I find out more. I had called LG and they told me it's a problem with Gemstar and an upgrade that is going on with them. Not a TV problem. We will see.
