Our computer was working perfectly fine until this morning. I turned it off because I left the house for about an hour.
When I returned I tried to turned the TV on but no picture came on only a sharp, squeaky noise that stays on. I can't even use the TV button to turn it off. I had to unplug the TV because of the noise.
Please give me some advise. Also, do you have any idea how much it would cost to get it fix?

With Direct TV, you should use the video input (composite video- yellow/picture, red/right stereo, white/left stereo) OR component video- (green/video, blue/video,red/video white/left channel stereo, red/right channel stereo)
the antenna connector should never be used anymore unless connecting an outdoor antenna or VCR.
if one of your input connectors is damaged, it is not likely that is will be repaired without replacing the entire circuit board (expensive!!!). just use a different "input"- there are usually at least 3 on most TV's
Go to "Picture Boost" option in the "OSD window". Then turn on the "Bright Frame" option and after that make the "Frame Size" to 100. That's it now you can get a perfect sharp image...it worked for me.
I don't know if I can solve this here. But the beeping noise is your pc trying to tell you what is wrong with it. Somewhere there are pc beep codes. http://www.pcstats.com/articleview.cfm?articleID=1223 If these can't help you just put "computer beep codes" into google. Here they are: Beep Code:Description of Problem:

One Long Beep, Two Short Beeps

I'm having the same exact problem with mine! I'm looking for a solution also. I opened up the back of the TV and blew out the dust. Then I checked all connections. I put it back together and plugged it in. Now it doesn't make the high-pitched squeeking sound, but I still don't get a picture. My guess is the picture bulb is burnt out. I'm trying to find one online and am planning to fix it myself - wish me luck!
