I had the TV connected to my PC when it broke, I restarted the computer and the TV kind of freaked out. Then, when I would turn the TV on, there would just be a blue screen... after a couple of hours of trying to get it to work the blue screen started turning black. I would try changing the input from PC to TV, but no buttons work on the remote or on the TV. I have to unplug the TV to get it to turn off.
Any clues? Someone told me the tuner. But I don't know how the tuner could make no buttons work, etc. I'm thinking the motherboard.

I appreciate your effort.This is the sad story of many a TV owners round the world. Four years is about the average time for the first break down in your kind of TVs. Power supply board in your TV appears to have gone bad, but it has to be confirmed by proper voltage check. I can understand your eagerness to do it yourself. But again to do this you need a certain amount of knowledge and expertise in the subject.
Please consult a good local Technician to take care of your TV.
The USB entry is mostly used for a foto slide show.
Please read the owners manual before plugging in any kind of USB sticks or other cable's in a TV set.
It can damage the set when there is a ground connection between some devices.
Thanks for using FixYa. Please check the following— 1. Is Power board output +5V? 2. Is J1 (#19 in the right diagram)connector good? 3. Is DC-DC OK, check the voltage at J1 using a
multimeter. 4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an
IC tester or an oscilloscope to check this IC. After checking this if it still doesn’t
work then check P3 D-sub Input (on the D-board). See this schematic for

I crushed my AKAI remote a week after I got it and I purchased a Logitech Harmony remote. It's kind of expensive (100.00) but you install the software in your computer and connect the remote to your computer. A screen comes up and you can type in an unlimited number of devices. All you do is put in the brand and model number and the computer will program the remote for that device. I have at least 10 different devices programmed into mine and works perfectly. Actually the price isn't bad because they wanted 85.00 to replace the remote just for the TV.
There are multiple reasons due to which the tv has no picture or sound/Blank Screen. First try and use the TV with a DVD palyer and see if it works. Also try using HDMI cables if you are using Component cables or component cables if you're using HDMI cable. This kind of issue arises when the control board is faulty(in case of no picture and no sound).
If it doesn't work then it can be due to loose connections,burnt components and/or faulty Control board. You'll need to open the back panel of the TV. The first thing to check out would be loose connections or any burnt components on the control board.
After the connections are checked you'll need to check for the control board of the TV using a CRO(Cathode ray ossciloscope)/Ossciloscope for bad IC's and other components. If you have a CRO then its very easy to check for a bad IC by desoldering each and every IC on the board and then checking it by a Oscilloscope. You cannot check the TV's Control Board using a Multimeter.
