I have a monitor for about 3 years now and didn’t have problems, nor signs of possible dieing screen. Today I’ve turned on the computer booted in to Windows and spent about 1-2 hours, checking mails and surfing then left the computer there, doing nothing for about 20 minutes.
The picture turned black all of the sudden, the monitor light in “No signal” color then into “Signal” then off, then comes back with “signal” color goes into “No signal” etc. It would not stop but, it didn’t write the “No signal” message out as usual, only the light was changing, and when turning off gave a very slight puk sound (which it stopped doing ever since, but did it for like 2 hours at every turn off).
In the mean time the computer was working. I’ve restarted but nothing happened, the screen went on with its odd new routine and the computer seem to be loading up normally only without a screen or picture. I’ve replaced the power cable of the screen, tried a different VGA connection, then replaced DVI cable, eventually put it on the laptop as second screen (through a VGA cable).
When I’ve replaced the power cable it stopped going from off to on but stayed at “no signal”, I’ve plugged in the laptop and tried to put it out on the monitor, which reacted, did a slightly viewable light blink in the top part of the screen then went into no signal then blinked again then back until the laptop gave up trying and switch back to it’s own screen. The screen returned to no signal.
I’ve took it apart now, but cannot find anything damaged inside, I’ve looked for damaged capacitors in the PSU of the screen, but they all seem fine. I wonder what could have happened, anybody has an idea what to check to see what’s wrong?
I’d love to fix my screen since I like it a lot, and I don’t really have money for a new one. Please help fix this (figure out what happened).
Ps.: the screen brand and type is in my signature.
