Question about Computers & Internet
I've a Proview pl713s LCD monitor that has suffered damage from a power surge. I opened the monitor and all the circuit boards look clean (no burns). However, when it's given power, the power light flashes fast and continuously, but the screen stays black (with or without a signal feed). The VGA cable connects directly to the same circuit board as the ribbon cable going to the center of the LCD screen, and this circuit board is also connected to another circuit board that has components similar to those in a PC power supply unit (and to which the power cable connects). From that circuit board, 8 wires (4 connectors) connect to the side of the LCD screen. The first circuit board has a microcontroller and a has sticker labeling it with 01FM713B J52-001 The second circuit board is stamped by Mirage Electronics Co. and has a sticker listing a few numbers also. Would the surge damage have stopped at the second circuit board (maybe power is simply not getting to the LCD panel) or could there be damage to the first circuit board and possibly the microcontroler also? Just wondering what I should try to replace to get it working without buying another monitor. Also, none of the wires that I can see are burnt or melted. If it would help, I can provide pictures of the parts in question. Mirage Electonics Co. LTD. PI-170DTLA REV.A DATE: 12.03.2005 200-000-170DTLAH VERSION: A The sticker just below the stamp is marked: 860-ABO-190DTLA-A2H PI-190DTLA K15-007 M3 4170033 I need to know what is exactly IC 202 ( B0506 817B if I have good eyes, beacuse the element is damaged).

You probably have a sacrificial diode that blew out to save the rest of the monitor from further damage. The manufacturer should replace it with a refurbished one at little and sometimes no charge (comparatively speaking).
