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.

    Take it to the reapir shop or buy the tools and learn how to go about fixing it as I indicated, you need to do the troubleshooting by first looking at the power supply filter caps, voltage checkings, etc. If you are not sure what you are doing , then leave it to the pro isnce we are dealing with high voltage that can kill you.

Try code 1234 or 0000.

Otherwise try unplugging the power cord to the set and leave it out overnight. This should reset the internal memory to the factory defaults.

Good luck and post back if this helps.

Hitachi 43FDX20B, watching tv, screen went blank, no picture, no sound turn off then back on power light on but the same nothing


The TV computer may have detected an error. See if the problem persist after unplugging the device overnight to reset it. If it does not, the issue may be with the board or its power supply circuit. Probably loose soldering or leaking capacitors.

The TV is on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.


If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

on the back of the TV where the power cord plugs into the back of the tv there is a small black on/off switch- it's not as obvious as you would think.... but that was turned off. Not sure how that happened since the back of the Tv was never touched when it went dead- but I unplugged the cord from the back of the tv and from the outlet and reset that switch and it worked.
