Question about Polaroid FLM-3232 Television
When I plug the TV in and push the on button, nothing happens. It just stopped working. I opened it up and put a voltmeter to the connections where the transformers supply DC to the PCB. There was no voltage but the transformers were supplying around 80 Volts DC. What do you think is busted on the power regulation board?
First warper2001 your power supply is probanly bad the voltage checks was you getting 80 volts on the output side of the transformers each one should be labeled as to the output voltage, at least one of them should only supply 24 volts, the transformer went bad probably overheated and melted the protective coating in the trans and let the voltage increase. could have burned out lots of things. unplug it, use a screw driver and short across the plug ins and the ground on the cord to drain the capicitors in the unit. the ohms check the components through each and to ground. check for opens and shorts. when checking a board remember that you will get a little bled back because you cannot isolate the parts. so most of you ohms readings should be large amounts of resistance if not you have a problem with that component, wire coils excluded. ie transformers they are best voltage checked. hello motorcity kid. i sent you a buddy message but also remember these items of advice.
