Aquired this moniter a couple of days ago. It was sold as "unit powers up but no display". From the description I thought it might have been a PSU capacitor problem.
On plugging it in, the power LED flashes blue, indicating no input signal. It also displays some kind of calibration/setup screens (colour bars, greyscale bars, blue, red green screens etc.) continuously. The only way to stop it was to unplug it from the mains.
I opened it up to check for bad caps anyway, but it looked OK. I suspected a corrupted EEPROM. Googling the number on the control board turned up nothing. I wondered if there was some kind of service menu that I could access. I jotted down the different combinations of button presses using the buttins on the side of the monitor. There are 5 buttons on the side, so that made 31 combinations.
I finally found the combination of "Vol", "Source", & "Auto" brought up a DEBUG message. Pressing the "Menu" button brought up the "burn in" menu which was set to "ON". I used the + (or -) button to turn it off. Pressed "exit" (Auto button). Pressed "Auto" button again & the screen displayed "No signal" for a few seconds, before going into standby. Yipee.
Not bad for a total price of £11.50, plus a lot of button pushing!
Thought I would post this as I couldn't find anyone on the net with a solution.
