TV went black but has sound- Dell Flat screen

The TV went black but we still have sound. It feels hot, so we turned if off and let it cool, but that did not seem to help. We checked power supply which is all set. It's just the picture that is out. How do I fix it?

Hi

Do you have the tools and equipment necessary to do an electronic repair? These are highly sophisticated devices - not user repairable. If you have the equipment and source for parts then begin with the set's internal power supply and troubleshoot as required. If you do not have the equipment or training do not get into that set. Even the static from your hand touching a circuit board could destroy expensive parts. Call Dell and they'll recommend a local service center.

If Your screen shows a: white vertical line on a black screen or, a white horizontal line on a black screen:
Your TV vertical or, horizontal power transistor or, chip is getting too hot.
A vertical line indicates the horizontal circuit is at fault, a horizontal line indicates the vertical circuit is at fault.
To troubleshoot: Turn on your TV untill the line shows then: after about a minute, remove power (unplug) the TV, remove the TV back cover, carefully using your finger find the too hot transistor or, chip; or, use component coolant; spray the too hot component with a component cooler repower the TV, until the screen comes back to normal. To fix: apply white sylicone coolant cream to the back of the too hot transistor or, chip. or, if there is room, a small fan can be wired in to cool the part. Radioshack sells the cream and, also a "component cooler spray" that should find and, fix this problem, also; with power removed you can, if you feel it is safe; carefully (with only one hand) feel the part; it will be very hot! (it could burn your finger!) Do not touch anything else! (this will not hurt the tv; when the picture comes back on (the offending part has cooled) you have found the problem part.

HELP OTHERS LG32LC7D FLAT PANEL TV

MOST LG PROBLEMS HAVE NOTHING TO DO WITH THE INVERTER BOARD AND THE INVERTER BOARD WILL NOT CAUSE THE PICTURE T FREEZE. THE 2 MOST COMMON PROBLEMS ARE THE POWER SUPPLY BOARD ( DEFECTIVE CAPACITORS) AND THE MAIN TOTAL ASSY. THE DESCRIBED PROBLEM ABOVE OF PUTTING A FAN ON THE UNIT IS A TEMPORARY FIX. REPLACE THE MAIN TOTAL ASSY.

LG 32LC2R screen goes black after 2 sec.

My LG 32lc7d 32 inch TV is 9 months old (December 2007 to September 2008) and now the screen goes black with sound and the channels will change I can hear them. Also when the TV is fine if I touch the remote it freezes the picture, so turn it off and on witch does not respond to the remote for five seconds, turn it on again & it works for 2 to 3 hours then same problem. LG claim its a software problem, well I got link to the firmware update down load to my memory stick and stuck it in the usb port on the back of the TV, software update fine no problem, TV reset all my preference are lost no problem I can set it how I like it ,but now worst things are happening the screen goes black after 15 to 20 minutes and no sound now ,so the firmware did not work but cased more problems and less viewing time .NNNOOO more LG product for me in life again .
I bought the TV for $1000 us and the DVD up converting player for $110 + sound system
So I could 1 remote to make life easer for me, but life is better for LG now since they have my money and all I have are their problems.
We should come together and attack LG about this problem or boycott them and their products for good, hundreds of thousands of people have this problem and nothing.
What’s the sense of a warranty if there no fix for your problems and you can’t get your money back. I have bought so many LG products and now no fix. There are millions of people who don’t have a $1000 us in there bank account..
I now feel like I was held at gun point and robbed by millionaire.
