    I called them and told them they sent the wrong adapter. they said they would sent the right one in 2-3 weeks. 3 weeks later, no adapter, i called and now the number is not available from my area. web site is also forbidden. called the number on the invoice i got with the wrong adapter and he said the pltv-3250 power supply is backordered and no idea when it will be instock.. here we go again.

Mine just had bulged caps no burnt spots, replaced caps on one it worked. have a few more that need the op amp ICs replaced also.
these boards are NLA so rebuilding is your only option

A possible solution would be to obtain a schematic for the power supply. If we're technicians, this should work out for most of us.

I have spent days looking for infomation to fix my zero power PLTV 3250, my phone number and web listed in the manual didn't work either. I saw that the Protron Company filed for Bancrupcy June 10th....so where/how are are you finding parts?
Also do I unscrew the screws on the bottom back to look at the guts you have posted?

Remove pwr board--inspect and you will find a heavy current diode which has eatin its solder pad area--if diode checks ok,repair it's connection.Install board and hook back up.Check for shorts in circuit.Cross fingers and plug her up------good luck

Was watching the televisions and it just went out. Unplugging it didn't reset it and the power cord is in pristine condition. Is the problem fixible?


Power supply failure in this Spectroniq/Protron PLTV-3250 is very common. That will be the first place to check.
Check the power supply; look for bad caps with leaking/bulging tops, check to see if you have standby +5vdc at the power supply connector, the front red indicator will not be on if you do not have this +5vdc standby voltage due to shorted out Q7 and ZD4.

No power to my protron PLTV-3250.


First make sure it does have at least red indicator on the front panel, if not, the standby +5vdc is not working, coomon problem with this monitor is dead power supply due to bad caps, shorted transistor and Zener Diode in the standby power supply.

Protron lcd tv getting no power


I have the same problem. I am told that I need a new power supply (adaptor) but from what I am reading on the Net, they are very rare and TV repairman told me he cannot find the part. I heard that Protron is out of business.

TV DEAD


hello, the first thing to do is to check the power supply, meaning check the main fuse and burned components,if do not have any electronics repair skills call the repairman, but first carefully open the set and check the all the fuses.
