I have an acer lcd monitor .when i power on the blue buttom acer logo displays for seconds and then black screen ;did anyone had this trouble i check the mainboad power it seems ok

hi how about the power light indicator does stay?. if no, it was a power supply failure. if the light stay then no display totally black it could be either the back light, inverter board or in the logic board ( main board ). to isolate the problem you will need a digital tester, to check turn the power on then check the inverter_on signal if their is a voltage around 4vdc and have a 12v dc supply then the logic board is good. it was an inverter board failure, check for shorted component.

No power my LCD TV monitor 900t

Well, that looks like you have what we call a dry joint on the power supply connector of your monitor. With experience , i have discovered this to be a normal problem. Get a compute technician to open up the monitor for you and then take a closer look at the circuit board where the power supply is connected. Check for any dry joints (this means that there is a component on the circuit board that is directly related to power supply, and it is not properly attached to the board (soldered). Notice all the dry joints and use a soldering gun to put them back together and try to power the monitor. Check also for bulged or leaking capacitors. Replace them with the same type

LCD working but how to fix red,yellow,green line on display and power supply dead how to fix and display shaking pictures please urgent reply me thanks

My advice, dont make any attempt at repairing the circuit boards inside this unit.
The power supply is more then capable of giving you a fatal electric shock.
The boards in these screens should be replaced as they are not designed to be repaired at component level and fitting replacement boards without knowing if the board is faulty can introduce further issues. Many suppliers will also refuse to take back any boards that have been fitted..
Take the screen to an experienced repairer or replace it..

Monitor won't power up the indicator just blinks on and off different monitor on the same computer works fine

Hello Sir, hi, your monitor is on standby mode, which means the power supply cannot power up the main circuit board, this is mainly cause by a shorted component that need to be analyzed and replaced, This symptom can also be cause by a defective switching regulator section of the power supply. We usually replace the entire power supply board. if no replacement board is available then we repair the board as our last stance. If cost of repair exceeds a new one, we dump the monitor and buy a new one instead.

Monitor fuse keeps blowing

There is definately a shorted component that causes the fuse to blow. Nomaly the ceremic capacitors are the cause of the problem. Check to see if there is visiual dark or burnt ceremic caps with label sameting like this "SCK 083" near the fuse area and change it. Hope it helps,cheers.

Initially, pls check D854 on the Power Supply/Logic board. It is a dual diode. If you would prefer board replacement rather than component level repair, this might be of help. This of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

This is of course in addition to checking the usual, power cord, fuse, outlet etc.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

Power board malfunction


There may be four (4) ways the repair could be done:
1. board - an entirely new power board maybe available from the monitor manufacturer or you can Google for OEM provider;
2. board - a refurbished/reworked board may be available, again you have to Google. Both 1 & 2 would require that you search for the actual PCB assembly number;
3. use the power supply board from an identical unit that has defective LCD panel, inverter or other problems/defect other than the PSU; and
4. component level repair - determine which components in the power supply are defective and needs replacement.

All of the above would require time. Time to look for the replacement board, time to determine which component to replace, time to do the actual repair.

Cost - depends on the tech. Of course board assembly would cost more to purchase but should be relatively easy to perform and therefore should not be expensive in terms of service. On the other hand, component level repair often would be cheaper in terms of parts purchases but would cost more in terms of service fees.

Taking into considerations the above factors, it may be more to your advantage to do the repairs yourself (no service fee). Still should you be uncomfortable on a DIY, then the cost of repairs might justify the purchase of a new LCD monitor instead.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Benq screen shuts down when pc is plugged in

If it's a 71g and not 71g+ resolder transistors 2sc5707 on invertor board along with grey condensers and inverter transformer.This should solve the problem if it was display shutting off with power led remaining on.Otherwise check power section.

Monitor randomly shuts down

This is either power supply (not usually), backlight drawing to much current, or most likely an invertor board component failure. Built in overcurrent protection on many of these boards will provide a shutdown signal. Weak transistors will crash when they get hot. Hp monitors are notorious for inverter problems. The time between blackouts will decrease until it no longer will light at all. Repair or replace the invertor.
