Question about Polaroid Televison & Video
My TV will not power on. The standby LED light is lit, and the set has power, but nither the remote or the power button on the device will not work. This happened today.
I am assuming this set employs a switch mode power supply as virtually all TV's do these days, the fact that the power LED is on means that the primary fuse is intact, usually means that the primary side of the supply is also working, firstly check the electrolytic capacitors in the supply especially the startup cap which is normally of low capacitance but high in voltage rating, eg: 2.2uf 450V, if this cap leaks it can cause the supply not to fully start. If the problem is still there you need to check that the supply is working, do this by disconnecting the main rail on the secondary side, this will be the highest voltage output usually anywhere from 80-135V and hang a globe of the same wattage as that stamped on the back panel of the TV, the globe needs to be a standard incadescent type that you use in your home lighting, switch the set on and if the supply hiccups then check for leakages in any of the diodes on the secondary side, best to disconnect one leg of the diode. if the globe lights the supply is running, the indication is then that the protection circuit has activated, although I do not advise disconnecting the protection circuit, I have done this to trace a fault, then reconnecting it, normally any faults on you main rail will enable the protection. if this doesn't help, I advise telling me more about the set.
I hope this helps.
