Power Surge damage. Suggestions on which part to replace.

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). Please help me I can not find scheme

    Same problem same board.
    Measured the voltage on the 6v pin out from the power supply. showing 2 volts.
    Feel the issue may be with the transformer 730-102-1700tla-ah 
    Any ideas were i could get one from, or what it may cross reference to.

    same problem. Seems like it depends from the tansformer on the power supply board, but I cannot find any code to identify that transformer and then to get the datasheet

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).

Insignia 22" flat screen tv.


I'd guess that the surge damaged some resistors on the internal circuit board, possibly a capacitor. You may be lucky if this has an internal fuse, in which case the fuse may have blown, saving the main components. Best course of action is to take it to a TV repair shop or similar to have it checked out

After a storm the other night my Proview PL866s amber light is blinking - however when I press the amber button (which usually turns green and then it works) nothing is happening except blank screen and...


If this happened after a storm, the monitor may have been subjected to a power surge, which unfortunately might have killed it.

If you have another monitor (or a friend who has one) try plugging that other monitor into your computer. If the second monitor works, yours will need to be replaced as the input was probably destroyed by the power surge.

If the second monitor also doesn't work, there may be a problem with your computer, most likely with the power supply (this is the part most often damaged by a power surge). You may want to have it examined by a professional computer repair person at that point.

Hope this is helpful!

A good rule of thumb to follow is: if the power button turns orange/red when it goes out, it's usually a problem with the monitor. If it stays blue or goes off, it's a problem with a driver or cable connection. Good luck!

I have a proview 22 inch monitor model 2200w it will not come on


Check power supply DC filter caps first.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums

Beware this monitor! PL713s


Probably a good solution. 17" LCD's are pretty inexpensive these days and probably cost as much to diagnose and fix this one. You can purchase on-line as well. www.tigerdirect.com www.newegg.com Good luck

Power Surge damage. Suggestions on which part to replace.


I would start looking at the power supply, it's usually a separate board where the a/c line plugs into. In many cases i have seen that the problem you described is from a damaged power supply, sounds like something is shorting causing the power supply to continuously come on and off. I would first check the capictors to see if any of them have blown, usually cylinder looking and sometimes you'll see an X or a K at the top of the cylinder, if it's blown then the top will be bulging out instead of being flat. If all those look good then there is probably a short somewhere else like in one of the transistors, if so you'd be best to just find another power supply board to replace.
