I HAVE DELL LCD TV SCREEN 2007FPB SUDDENLY IT DOES NOT WORK WHEN CONNECTEC TO POWER SUPPLY, PREVIOUSLY IS GOOD WHAT IS THE PROBLEM & HOW MUCH MONEY NEED


First check your monitor light is blinking or not. If it is then--

Check your monitor cable which is connected your CPU. If it is ok then
Open your CPU and unplug *********** board power cable and re-install it.
And also remove RAM and clean with a brush softly and re-install it.

Best of Luck

CAN'T GET THE MONITOR OUT OF POWER SAVING MODE


Hello,

If you have a blinking power light and no display even when you first power up the unit then its not in power saving mode. The blinking power light indicates a failure of the filter capacitors on the power supply board. This is a very common problem with LCD monitors after a few years of service. The power supply can be repaired by just replacing the defective filter capacitors. Here is a picture of the power supply board with the bad caps circled in yellow and below that is a link to a full repair guide showing how to open the unit and what to replace including a full parts list.

Look for cold solder joints, shorted transistors, bad fuse, bad caps.
See pictures here: http://s807.photobucket.com/albums/yy352/budm/Dell%20E153FPB/

If you are going to DIY and already try the monitor with another PC, 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 DELL monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/

Where can I buy a power supply for an AOC LCD monitor model TFT 1780?


hi, i don't know if you will ever find just the power supply board for this monitor. i repair lcd monitors for a side business and i have never found the exact power board i needed for any of the monitors except for dell 17in. you would have to look on ebay for another broken monitor just like your with a working power board, broken screen maybe. that being said, why do you think you need a power board complete? the parts on the board are replaceable. maybe you could post a reply so i can read to help with what the symptoms are and help you diagnose the problem components? if you posted pictures in your reply of both sides of the board, it might help me describe more in depth.
