The picture is at the top left of the tv and everything else is black

If you have tried using different input devices, looked for loose contacts
in power outlet, RC Jack, cable and connectors, the TV might need service.

I had a similar problem on my Toshiba Regza but trying my fix couldn't hurt. I use a satellite dish for TV (if you do the same this might work)... I turned off my receiver, took the programming card out, cleaned it with my shirt (especially the part that looks like a computer chip), put it back in the receiver, turned it back on and when everything reinitialized the black rectangle was gone.

Hope this helps.

check and see if your tv has PIP (picture in Picture) which you turn on and off with the remote. If you do you have PIP turned on, but not set to any station.

There should be a button on your TV remote that will be called "Display" or "P in P".
The display button usually displays which input you have selected, such as: SAT for Satellite; AV1, AV2, AV3 or AV4 - depending on how many inputs your TV has, to plug in devices like a VCR or DVD recorder/player.
Otherwise, if you have a more sophisticated TV, it could be that you have accidentally pressed the "P in P" button, that selects the Picture in Picture mode. If you have done this, your TV will display the main picture of the input you have selected, plus another input, (such as SAT or AV1 or AV2 etc. as I've mentioned above). If the AV1 or AV2, etc. input is not active (not switched on) then that input will only display a blank (black) picture in the top left corner of the screen.
Hope this helps...

help me aftervpower off by cable co installer
now have NO sound
but have the sound register graph rising 0 - 50

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
