SOURCE: microwave blowing fuses when setting programme

suspect high tension diode or bleed diode faulty. easy to replace but!!!!!!!!!!!!!!!!!!

BE CAREFUL. THERE ARE VERY HIGH VOLTAGES PRESENT IN A MICROWAVE. YOU MUST SHORT CIRCUIT THE CAPACITOR WITH A GOOD QUALITY SCREWDRIVER IE GOOD INSULATION. VOLTAGE CAN BE UP TO 1500 VOLTS AND IT CAN KILL.

IF YOU ARE NOT SURE WHAT TO DO, GET SOMEBODY IN

SOURCE: Sony KV-35S42 35" keep blowing MX0841 and .1 fuse resistor

Normalmente cuando falla la fuente se dañan los transistores convertidores, la resistencia 607 de 0.1 ohmios los condensadores C609, C610 de 0.47 mf. C611, C612 de 0.22 mf.
En nuestro caso basto con cambiar el MX0841 y R607, ya que el daño se debió a una sobrecorriente provocada por la salida horizontal, esta fuente e mas robusta que la de otros modelos ya que accidentalmente se provoco un corto en la salida del B+134 y simplemente solo se daño el MX0841 y la resistencia R607, se cambiaron y la fuente volvió a funcionar perfecto

SOURCE: 1992 volvo 240 keeps blowing overdrive fuses

More likely that the solenoid in the transmission is shorted to ground. Has any new electronic equipment been installed recently, like stereo, alarm, etc?

Sony 6060F blown fuse


hello!
there is a standard procedure for proper replacement of blown fuse: CRT TVs: unplug degaussing coil, replace blown fuse with 2amp fuse and turn on the set. If it works, reconnect degaussing coil, replace the fuse with correct value(5-8) amp, depends on model(see fuse note next to holder). Enjoy the show! If in a process of replacing the blown fuse with 2amp w/o degaussing coil it blows again, forget about the next step. Set need repair. It could be an easy one, replacing 1 or 2 shorted diodes or bridge rectifier, but could be real piece of work if the power supply got "fried". If your knowledge won't go further, than fuse replacement, I'd recommend local TV repair shop.
good luck,
Alex.

My sony receiver tuner wont turn on. It was working fine yesterday now it wont power up. The fuse near the plug wire inside is good. Any suggestions


Fuses almost never go bad something causes them to blow. Even when a blown fuse is found in electronics just t replacing it can cause more damage if something caused it to blow, a repair person looks for bad parts before replacing a fuse. Only microwaves are known to blow fuses and replacing the fuse fixes it. About the only thing that people can do is unplug a short time and try it again. And need i say is the power outlet ok.

When t.v. is turned on, black picture and no sound.


Usually when the fuse blows its due to a component being shorted and if you increase the rating of the fuse you can cause other components in the circuit to blow. The pop you hear was most like a capacitor on the D board. The D board is no longer available from sony as its listed as discontinued. You will most likely have to have a qualified sony service tech trouble shoot the circuits on the D board to locate the short as it will be outside the scope of a do it yourself type of repair

FUSE SPEC FOR SONY KV-36FV16


The rear panel nameplate will state the unit power requirements. Look for number of amps draw. Let's say you read "2 A". Now, depending on where in the circuit this fuse is, your fuse size will be no more than two amperes (sometimes slightly greater if slow-blow fuse spec'ed). So, if your fuse is located immediately near the line-cord entrance to circuit board, start with a 1.0A fuse. If that immediately blows, then increase to a 1.5A fuse. Repeat until 2 A fuse is reached. If still blowing, then there is a problem with the set, either power supply or tube.

The main fuse should be a 4 amp fuse not a 1.25 amp.

Nothing works


The fact the set blows up the correct fuse is because it has a short ahead in the circuit,it could be one of the diodes(4) that is shorted,if one of these guys is bad all of them should be replaced with the exact replacement,ahead of them it should be a regulator and he is bad (shorted) it could have taken the diodes and the main fuse.The cause might have been a power surge.If you are familiar with tv service you can check the regulator and the diodes before you put in a new fuse,if you are not too familiar be safe and take the set for an estimate.If you suspect power surge or lighting damage it might not be worth repairing.Let Us know if you need more information.
