check for voltage at your U4 IC voltage regulator which steps down the 3.3v to 1.8v [url]https://youtu.be/uqePKWjrlnw[/url]Re: Polaroid FLM 2632 wont power up,...PKWjrlnw[/url]Leave a comment:

Re: Westinghouse SK-32H540S Catastrophic inverter Transformer Failure.
so on my tv I bought the same transformer that was still in spec with the other 2 looked the same ohm ed the same from a vender in china it took three weeks for it to come in (i think it is supposed to be 4% tolerance of voltage) I cleaned the carbon off and then I soldered it in and the tv works fine now it has been running for months no problems watching tv or moviesLeave a comment:
