LG Studioworks 520Si monitor; doesn't power up after disconnected the deflection coils
Hello,
I have a bit of a problem with a LG Studioworks 520Si CRT monitor. I got it today and powered it up, but with no computer or whatsoever attached. Everything seemed to be working fine. The next thing I did (my reasons are unimportant ;-)) was disconnecting the four wires which connect the 2 deflection coils to the big circuit board of the monitor. When I tried to turn it on, the monitor began producing a sort of a 'beep' sound, which repeats itself very quickly (until I pulled the plug :-)). Also, the LEDs on the front except for the power LED are blinking in the same 'rhythm'. I disconnected the power cable and plugged the 4 wires back in, but the problem persists. I took a look at the board, but I don't see any damaged parts. Has anyone an idea on how I can solve this, or did I just destroy a good monitor (hopefully not :-)). Thanks in advance. |
