    TV will not turn on. It did this a few months back and finally one day we tried it and it came on. We decided then to leave it on all the time then one day the electricity went off in our area and guess what? Yes, we cannot get it back on. Any suggestions or solutions?

I HAVE A PROTRON PLTV-32CM AND LAST WEEK IT JUST WENT OUT. NOW ALL IT DOES IS WHEN YOU CUT THE POWER ON IT JUST GOES AFTER ABOUT 3-4 SECONDS. I REMOVED THE BACK COVER AND ALL THE CAPISTORS LOOKS OK. WHAT...


Protron's mainboards like to fry and a replacement is difficult to find. Protron tvs are built with very cheap parts and don't follow manufacturing guildlines very well and are difficult to find parts for. I would start with the mainboard as the power supplys don't usually fail in these tvs.


Best of luck and please rate if this helped :)

No picture on TV


First place to look will be the power supply module, check the 5vdc standby voltage and all other voltages as well.

The power won't stay on.


protron filed banruptcy so that they wont be responsible for selling you a lemon, they covered their asses, theres no solution to their tv or electronic problems, they are a bootlegged company, dont bother calling customer service they are some people in india telling you the same thing every time you call, in other words , they dont even know who protron is, they are paid to say whatever and probably paid one dollar an hour, my tv never worked i bought it from national wholesale liquidators and i suggest no one ever buys anything from this store either, they are a rip off! i lost $900. and sad to say so did everyone else that invested money in protrn/sprectroniq
