My Toshiba 32in tv wont turn on..the sound works the screen just blinks once like it wants to turn on.i have a gaming system connected..the sound only plays
If your TV stays on and and you have sound, but no image then it is 90% chance that the problem is in the back light inverters and 10% it is the T-CON board.
OK, make it 9% to leave 1% for everything else.
Inverter boards are the two boards that sit on the left and right side of the TV, are connected between each other with a strip cable and both are connected straight to the power supply board.
One of them is likely bad.
I'd go replacing both.
it looks there are several different power supply boards for this model, which means there could be different inverters too.
So I do not want to mislead you and send you somewhere without knowing what's in your TV.
Open it up and look up the inverters, then find some alphanumerical tokens on them - preferably on a label, but possibly printed on the board as well.
Then google for that.
Hope this helps.

Where can i find a replacement for my broken
The tvs screen panels are 90% important to the tvs.Sorry,LCD tvs screen panels or any other tvs screen panels for that matters are limited production by the tvs industries.No, where u will able to find and buy or replaced the tv LCD screen panel,but must buy the LCD screen panels from the tv industries themselves.They'll sell it to u,but they'll charge like the new LCD screen panel same as a new tv.Sorry ur tv now dosen't worth as a whole tv anymore,now it only worth as a salvage tv for it electronic boards for parts,that it.

Picture size option does not come up in picture settings
While I can't confidently say how it is on this TV without having to go and check it, from the top of my head I'd say I've seen quite a few different TV models to NOT have picture format accessible through the menu, but only through the remote.
Whether it's because there's not enough memory to fit in the whole money (a good possibility on a low-cost device) or whether it's because they're rushing to deliver this model and move on to something else will remain unknown.
But my guess is it simply cannot do it.
Hope that helps.
Remember, don't kill the messenger :-)
