Have flm3232 model 3200 blowing fuse unpluged everything going from power supply and still blowing fuse how do I locate new power supply #8090 I think . not a repairman

Unplug the unit. Start in the power supply. Unplug any cabling going to the PS Board to minimize erroneous measurements. I am hoping you are technical since you are going to screw around with the electronics so let's get to it. Perform a diode check and capacitive check on main filters to make sure the bridge rectification is good. Next, analyze whatever V (TDA, STK, etc) output module may be on the power supply board (PS).

Should everything look good, keep the cabling off the PS Board but make sure the grounding leads are still tied to it. Replace the fuse with same E and I ratings. Plug in the power supply. Fuse blows? If so, you missed the problem on the PS... go back and run diagnostics (continuity on discretes). If it didn't blow, hook up the cabling the way it was and turn it back on. Fuse blow? More than likely it will be your output transistors. Perform tests while unit is unplugged (diode function).

Good luck and don't get bitten!

These are prone to power spikes...and for that reason have a fuse located on the power supply board...known as fast blow fuses...which are glass and easy to see if they have blown..sometimes all you need to do is replace the fuse on the rear of the unit if you can locate a fuse cap...just unscrew and replace....Always unplug televisions and audio equipment and routers during power outages and thunderstorms as a preventative to blowing psu panels on electrical devices connection to your house mains for this reason .

Try unplugging the blower resistor, located under the passenger side, under dash area, put a new fuse in and see if the fuse opens (blows). If it does not blow then unplug the blower located in roughly the same are and plug the resistor back in if it blows then it the resistor if not it's most likely the blower motor.
If the fuse blows when both resistor and the motor is unplugged the you need to unplug the a/c head unit and see if it still blows(open fuse)
Hope this helps

Solution:
First, disconnect the power cable from the back of the external hard drive:
If the power supply LED continues to blink:

1. Connect the power supply to a different outlet (or instead of connecting to a power strip, connect directly to an outlet in the wall).
   
   
2. If the power supply continues to blink after changing outlets, this indicates that the power supply is defective and needs to be replaced.
   
   
3. If the power supply stays solid, then reconnect to the external hard drive and see if the drive spins.

this is a normal behavior if one of the power supply transistors have blown. take the unit to an enlectronics repair. they can either change the transistors affected (usually more than one) or replace the power supply board.

hello, definitely if your fuses are blown and your not able to circut trace and find the fualty compnents on the pb then repalce it with a working power supply this may help but also keep in mind you may want to check everything out first get your models service manual so you can verify voltages at test points. something is cuasing the fuses to blow so if you do change the power board and you blow the fuses again then you will need to trace the circut and find out where the short is and what panel or part is cuasing it .

hope this helps

check mcm electronics, if the fuse keeps blowing you have bigger problems.

I just fixed my proview 3200 that doesn't have picture but with sound.
First, thanks for the tips I got from this forum. I checked the 24v from the power supply board and that's perfectly working fine. I then check the fuses in the Inverter board. There are 4 white fuses (2amp I guess, i cant remember) and 1 black fuse (1amp/76v just behind the wire connector going to the power supply board). The black fuse is the one that blown out on my tv. This fuse supplies power to the LM358A IC. I know its not right but I just solder a thin piece of wire to short circuit this fuse. I'm lazy to drive to RadioShack to find this fuse. :)
....and that worked beautifully. Check the picture attached for what I did.

Hi,
you could try checking the plug fuse.
or opening the casing, and seeing if theres an on board fuse located near to the mains power inlet. usually a small glass fuse. 0.5 to 1.5 Amp quick blow type.
Make sure you switch off and unplug before attempting this.
if the fuse blows again, when you switch it back on, unless it,s warranted. Bin It and buy a new One.

you have defective power supply! you have shorted parts! like diode or regulator. replace the shorted regulator.
