Hello,
You can do this by yourself all you have to do is to open the back cover of the television to check the faulty components. to fix you must have basic knowledge on electronics .

The fuses are there to protect the set from catching on fire in case there's a short circuit inside the set. Now in some cases an intermittent short can work after you replace the fuse but if its burnt black or brownish, there's a circuit inside the set in one of the circuits. always use a 100 watt light bulb across a blown fuse if your not sure if there is a short. if there is, the light will absorb the short and glow bright. if there is no short the bulb will glow bright , then go down very dim. you could have a main power supply problem, such as shorted bridge rectifiers,shorted main b+ capacitor, Hot could be shorted, or the Vertical or audio output IC could be shorted.

I hope this help in solving the problem.....

Wy fuse keeps blowing


Fuses blown when an overload occurs. More often than not caused by a short circuited transistor in the main amp section. Possibly also on the power supply too.

Fuse blow each time I turn on air check for


disconnect the thernostat wires from the control board. Put a jumper wire between R & G put door back on and turn on power. Blower motor
should run, if it blows the fuse then you have a direct short between R &
G at the board. Do this with R and W(heat) and R & Y(cool).

By disconnecting the thermostat wires and reinserting them make sure that they do not touch when inserted into each terminal. If it still blows
that little 3amp fuse when jumpering between each sequence as mentioned above, then I think your board is bad. When Jumpering out the Y terminal you will have to have the AC wires still hooked up. If it
blows the fuse in that sequence. Disconnect the wires out at the condensor.

You mat have a bad contactor at the outdoor unit.

Black screen no video no audio suddenly now


This set is a 50" plasma. first check the AC power fuse on the filter board then: if it is bad: check the power supply by marking and, removing all the cables; (so you can put them back in the correct spot) except the filter board to power supply cable; that connects to the Power supply board. Then: replace the blown AC fuse and, re-power: If the power supply blows the fuse: again, the power supply is bad and, must be replaced or, repaired. If the fuse does not blow: turn off the set then: on again, reconnecting and, disconnecting each board cable in turn, untill the fuse blows again this cable leads to the bad board; replace or, repair the board that blows the AC fuse every time the bad board is connected, irregardless of which other cable to the power supply may be connected also; or, not.

PC power supply fuse - T6.3h 250v engraved on end


T = time delay (slow blow)
6.3A = 6.3 Amperes maximum load
H = HRC - high rupture current (as you specified a ceramic fuse)
250V = 250V AC rated

other letters you may see
FF = ultra fast blow
F = fast blow
M = medium blow
TT = very slow blow
L = low blow current
H = high blow current (glass package)
S = sand filled

Proform 570 blowing fuse


there are generally two control boards, I am assuming you looked at the lower one. I would first disconnect the power leads at the board and see if it still blows the circuit breaker (fuse?). If it does the check wiring for short. If OK then reconnect power leads and then disconnect all other wires (plug-ins) to the board and try again, each time plug a connection in and retry. (remember to disconnect power each time). I have a feeling the smoke got let out of this lower board and may need replacement. hope this helps

FUSE BLOWS EVERTIME I TURN MY TV ON. I CAN REPLACE THE FUSE AND DISCONNECT THE FLYBACK FROM THE CRT,TURN THE SET BACK ON ,CHECK THE FUSE IT WOULD STILL BE GOOD,BUT WHEN I REINSERT THE FLYBACK AND TURN THE...


Possibly a resistor that's becoming defective... it's changing value thus increasing current. like if the resistor has a rating of a 10k Ohm and now it's changing to a 30K Ohm and the current (amps) is supposed to be around .50Amps and now it's rising to .75Amps or higher, so it would blow the fuse so as not to further damage any other high voltage or sensetive component. Is the fuse you are replacing the same as rated for the tv? ie; 250V 1.25Amp FB (fast blow) or SB (slow blow) it should say on the circut board where the fuse plugs into.
