Takes to long for it to turn on. Think the switch is going bad.


I believe your problem is going to be defective filter capacitors in power supply. Classic symptom of taking longer and longer to come on. Will get progressively worse over time then wont come on at all. No need to replace the whole power supply board. Most knowledgeable repair shops will replace the swollen capacitors or you can try yourself if you are familiar with electronics.

The defective capacitors will usually swell up out the top making them easy to spot

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.

I don't remember exactly which ones I replaced.Look at the capacitors on the power board,and replace any that have the top,or bottom bulged out.The capacitors didn't cost much,maybe around $10 with shipping,depending on how many you need.Do you have your power board out?I hope this helps.If you have any questions,please let me know.
Thank You very much!

Polaroid DRA-01601A will not power up


99.9 % of the times its the capacitor which is blown. I had spent few weeks to investigate on this and ultimately found this solution. Till date I have replace two capacitors. To determine which capacitor is gone, Check on the flat silver surface of capacitor. If its not 100% flat it means its gone and you need replacement. Pl. check my attached file to understand on details of inside configuration.

Hopefully it works for you.
