    unplugging did not work, i agree it is probaly not a sleep timer issue. The TV is a JVC 47" LCD. It is 2 years old, # LT47EM59.

    No i am not going inside TV. when i hit the power button , the light stays on 4 30 seconds. Then it starts blinking. there is just a blank screen when the power light is on, then u can hear it switch off.

First off what is the make and model of the tv and how long have you owned it? If you haven't already try unplugging it for a couple minutes and plugging it back in. Then see if it will turn on. Most likely the issue you are having is totally unrelated to using the sleep timer.
Thank you,

    Are you planning on attempting any repairs yourself. You may need to end up taking the tv apart and checking for any bulged capacitors and then using a multimeter to check for voltages. If the tv won't turn on at all first thing to look at is the power supply board.
    Thank you,

    There is definitely a problem inside the tv. If you give me your zip code I would be happy to assist you in finding someone to give an estimate/repair the television.

    Ok, and just to make sure did you try plugging the tv directly into the wall and you had the same problem? Here are a couple tv repair companies in your area:

    If you need any further assistance please let me know.
    Thank you,

My flat screen tv wont turn on...what does that mean?

most likely your set has an internal failure and will need to be serviced. You can try unplugging it for a while, then plugging it back in to see if it will power up. But it is possible that you have a failure on your power supply board or the main board.

You could of course have a audio circuit problem with the set but there are some things to look at first.

1. does set have sound when a DVD etc is connected via a rear audio/video input? This will narrow things down somewhat.

2. are the speakers in the audio menu turned ON or OFF?

3. are you using a cable or sat box or a receiver in line for signal?
If so unplug each for a while and plug back to allow them to try to reboot.

Most of the JVC sets that are LCD the entire audio circuit is on the main board--one of the most expensive boards in the set.

Screen goes black tv stays on. Turn off and on and TV's fine.

I had this problem on my 42" Philips. Just got it yesterday and worked fine on the tv stand. As soon as I mounted the TV to the wall via wall mount system, I had the exact same issue you did. Figured it out today.

The wall mount was putting pressure against the center of the back of the tv (tv set had a slightly rounded back plate, and the mount was a flat plate). As soon as I put spacers (part of the wall mount hardware set) between the wall mount braket and the tv so there was no contact except at the mounting holes, the tv worked fine.

My theory is the pressure pushed the tv back plate against some board components which caused them to overheat (no air flow); or put pressure on internal connectors. I dont know.

Hope this helps, may not apply to your situation.
