Re: Polaroid FLM-3732 Turn on Off
These are known to blow caps. There may be a blown diode or transistor in the same circuitry somewhere, which either caused the caps to blow, or failed due to the caps blowing.
Also, were the caps replaced with quality same value, low ESR caps? Did you also replace all caps that were in the same circuit as the ones that blew? If not, do so. They have likely failed as well just not visibly.
Close-up pictures detailing the area that the caps blew would help. Top and bottom of the power supply. -
Re: Polaroid FLM-3732 Turn on Off
The Big 100uF/450 was bad and I replaced both of them with Panasonic Caps. Also I replaced all the 1000uF, 470uF and one 220uF. All of them I got through Digikey. I checked the big transistors and are fine. Not sure about the small ones on the back side of the board.Comment

For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.
Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.Comment
