| i have work in this tv proton for several times and i never hane any problem with the 5 volts stand by but always found a cap bad on 5 stby after replaced the caps if any vary has still problems with 5 volts stby chek ZD4 its close to the IC2its reading bad after you replaced this zener diode power will work 5 volts stand by missing | |

Ebay, I was able to repair the old one. After doing some comparison testing between the two. I found a zener diode that was killing the 5 volt standby voltage. It was neither shorted or open. It originally tested good in circuit using diode check on my DMM. |

| xtech, Where did you find a power supply?
Thanks |

| Update:
The company who makes the supply wouldn't supply a schematic. I found a new power supply and replaced it. |

| I sent an Email to FSP (the manufacturer of the power supply)
and requested a schematic. I’ll see how cooperative they are. |

| Only thing I know that it was not made by Proton---it was Protron Digital which filed for chapter 11 on 08. No idea about the manual though? | |

|
| Hello
I am working with a spectroniq (proton) model PLTV-3250 LCD TV. The set will not start I found a series of bad electrolytic capacitors in the power supply along with a small surface mount transistor, all of which I have replaced. The front standby light is not lit. It uses an FSP194-3F01 power supply. I have not been able to round up any service data for this unit. And they dont appear to have a website anywhere on the net. I need to know at what points in the supply I should be receiving voltage and how much. There is a noise that's barely audible coming from the top area of the set, I think its one of the boards that control the LCD panel lights, but I'm not 100 percent sure. Just curious if anyone has (or knows) where I can get a manual, and help steer me in the right direction. Thank you |
