My new TV - 3 weeks out of warranty - has just stopped working, no power to it at all. Have tried plugging it in to various sockets, nothing. Tried chaning the fuse, still nothing. Any other ideas before I call in the repair man!!!

Problem: No video,no audio, and no indicator.. Solution: Is this a new television? If so, then plug something else into the same socket.. If the socket is working then you should examine the TV to see if there are any signs of the electricity to the TV (exterior.. do not take it apart). If there is no electricity in the TV then it may have a bad power supply or a bad cord. Best thing would be to take it back.. Most TV's come with a warranty.. If the warranty has expired you can usually talk with the store and even with the manufacturer appealing to them that the TV should have lasted longer... I usually ask them if they can make a consideration in this case.. Sometimes they will. I once got a brand new Sony Digital camera that was out of warranty because I reasoned with them that a $1000 camera should last longer that one year and one week (that is when it went out).. Negotiating is powerful.. At least you are taking a shot... Who know? You may win. If the TV is used... Same as above with the tests.. I have repaired my own TV's before BUT I DO NOT RECOMMEND THIS BECAUSE IT IS VERY DANGEROUS. There is a high chance of deadly shock within the TV.. Don't take the TV apart yourself! You can find a used TV on Craigslist.. I have even seen people giving working TV's away because they just bought a giant screen or something....
Maybe faulty power switch or its blown a fuse or the powwer supply inside the TV is kaput.
If its out of warranty get in touch with a reputable TV mechanic and ask them to come and repair it. It might be good to get a ballpark figure on how much it's going to cost.
Instead of just unplugging the TV, perform a power drain:
1. Unplug the product's power cable so the device is not grounded to the house.
2. Press and HOLD the product's own power button for 1 minute to drain the capacitors.
3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and
hold down it's power button. Electricity can remain in capacitors and on circuit boards
enough to prevent normal functionality. By clearing the residue electricity, your product
will have a fresh start and many times this will resolve a buggy or non-responsive device
that appears to be dead.
If the TV still won't turn on, then it appears something is wrong with it's mainboard since the TV is still receiving power because the standby light is still coming on. The cost of fixing an older TV's mainboard could be costly or impossible if the part is discontinued.
Please try these preliminary steps.... 1. Check wall socket by plugging any other appliances 2. If it is ok, check whether power LED of TV is working 3. If power light is there, the problem will be with remote 4. For checking remote - Point the remote towards the Camera of a Camera Mobile with camera on. While pressing remote keys, we can find the remote LED blinking, which means working.
Try this one: 1. Unplug your power cord from the box (NOT THE WALL!) 2. Wait 3-5 min... No more than 5 MIN (very important) 3. Hold down the power and select button at the same time and don’t let go. 4. Have someone plug the power back in… and keep holding the power and select button. 5.Don’t let go until it gets to 0 (it's about 5 min) 6. Once it gets to 0 then it will stop counting down, that when you let go!! 7. Don’t touch anything, 8. The screen will reset and it will go blank. nad that's it
If you can describe it more then maybe the following may assist....
There are several types of plugs and sockets on TV receivers for many applications....A SCART type has many pins for the sound and Video outputs to various type of CD, Video, or surround sound systems, or games consoles.
There are also systems that supply a DC voltage over these various type of plugs and sockets to "drive" the input electronics at the far end of the TV receiver....A classic example is for a mast head amplifier which needs a DC voltage to make the Amplifier work and this is done over the TV areial connection so maybe this is what you are describing....More detail please...
