I would suggest to check the electrolytic capacitors that filter the 5 VDC, these caps become defective due to the amount of heat around them. These capacitors become leaky or bulging on the top or bottom.
Let me know if you need further assistance.

Our Polaroid FLM 3232 has worked for four years and now all of the sudden it won't turn on....seems to be no power supply...the red standby light is not illuminated....please help we love this tv!

I hate to say it, but it is prob the main board that went bad. (the board where all the inputs get plugged into) It is possible that it might be the power supply. One thing to check is to make sure you have 25v coming from the powersupply board to the connectors that plug into the main board. If you do have 24-25v than you will have to replace the main board. If not than the powersupply.

Camera say memory is full but wont let me format.

Sounds like the internal memory has failed.

I would check with Polaroid about repairing it. An alternative would be to try installing a memory card. If it works with a memory card, then the internal chip is definitely the problem.

See if a friend has a camera that uses a similar memory card and just borrow it for a few minutes to test.

No picture

Check the powersupply/inverter and the CCFL's. In my case there was a bad capacitor on the Power Supply, and the soldering on the CCFL's was iffy at best - repairing solder joints on the CCFL's fixed my problem permanently.

Toshiba satelite A100 no power at all

The ac power pack may be faulty, check it with a multimeter, the voltage should be slightly higher than the voltage printed on the label on the power pack.
If you can borrow another working ac power pack (has to be the same as the ac power pack), test it on the laptop.
Also reseat the RAM modules and the hard disk and see if it boots up.
If it is a bin job remove the hard drive, if the hard drive is OK, put it into an USB drive case and use it as an external hard drive.

I Have A Compaq Presario That Will Not Power Up.

It sounds like your power supply unit as some leaky components, normally the bad powersupply unit show these types of symptoms. Try borrowing a powersupply unit from a friend that is similar to yours and replace to check if the powersupply unit is the culprit. If cornfirm PSU, than you neet to get yours fixed.

Polaroid 3200

The newer technology has design issues due to the confined space where all the components are and not well ventilated. A good number of LCDs failed due to overheated components, specially in the power supply circuitry; once this parts become dry or leaking the LCD will fail to power up.
It seems like the power supply is defective on your LCD. Replacing or repairing it should fix your power up problems.

Let me know if you need further assistance.
