as you have a good screen, I would check ebay for the display controllers as there are so many available after shipment drops and kids with hard toys.
what you have been troubleshooting so far is analog , now its likely a digital issue , all you can look for is the the cpu is running,
is it getting the 5v + and the say 20 or so volts.

This fix is for those of you with knowledge of electronic repair......
The problem is a bad electrolytic capacitor on in the power supply board. The cap is a 470uf 16v (number C226 on the power supply board). Replace it with a 470uf with a rating of 25v to 50v and it should restore the power fucntion to normal. I have fixed six units this way so far. Hope this helps you all out!

I scratched my head over this for an hour. The manual says you can access the OSD from the unit, but I see no way to do this. From the remote, you have to select the "AMP" setting at the top of the input list. Then hit the OSD button. Assuming your monitor is set up correctly, this will bring up the On Screen Display. Then hit the "Menu" button also on the remote, and you can make your adjustments. Good luck!

without a remote and disabled keypad keys, the only other option, is to open the unit up a physically RESET the TV. remove the cables from the power board. i believe it has a phillips head screw. careful when you separate the rear cover from the front cover. there is a board screwed in the lower right corner, there is a connecter and a ground cable screwed to the rear cover. take your time prying on the rear cover. once you separated the two pieces, look for the light yellow board with your AC power source. Unplug it for 30 minutes and repeat the process. while your at it, also look down to the lower left side of the monitor. u should be able to see the keypad. press each button, while pressing, look to see if the button is pressing against the circuit board. it may be loose, try this test, u just may be able to fix your keyboard as well. hope this works out.
