Check the horizontal output transistor. Its probably shorted.

No power. Fuse was blown but replaced fuse and still no power.


If fuses blown there is a case to search for short circuited active parts examples are end-transistors caused by clipping speakers cable shorts leaking or convexed capacitors but any new fuse will blowing again and again also the bridge rectifier to make dc voltage inside the power supply of the subwoofer can caused this problem

In onida tv d2498 and fuse in power supply gone on connecting ac.Without main board installing please help


If it's not the main board that's causing the fuse to blow then you have a short circuit somewhere in the power supply. Check things like the electrolytic capacitors. The ones that look like little cans. They should all have flat tops. If any are bulging out at the top they will need replacing. Also check the bridge rectifier which is a black component usually standing up on the board with four legs. If there is no bridge rectifier there will be 4 rectifier diodes together. They are black cylindrical items with a sliver band on one end and a lead out of each end. They are usually located near to where the mains lead enters the power board. Other things to check are power transistors, they are usually 3 legged, (sometimes 2 legs if they are used as a diode) black items with their case fixed to a heat sink (aluminium block.)

NO POWER AT ALL


Hi
our tv set need to be serviced. Here are some tips:
1. Open main fuse. The fuse is clean but interrupted. You can try replacing it with one o the same value.
2. Fuse Blown or blackened. Short in the rectifier bridge or in the switching transistor. Out of the power supply: supply line rectifier (100/150V) shorted.

Smbs output is low


Check the AC mains rectifier dides/ [stalk]. Replace the main filter capacitor. Rectifier bridge. Rectifier diode at secondary voltage. Filter capacitor for secondary rectifed voltage.

Soundcraft GIGRAC 600 pre-amp power supply keep blowing the low valve resistor 1ohm. they are the resistor just before the bridge rectifier, for the low voltage feed. Once resistors replaced the unit...


The resistor is acting as a fuse and will continue to blow until you fix the REAL problem. LIKELY the filter capacitor(s) beyond the bridge rectifier are failing. One needs to use test equipment to measure the current through the resistor and see if it is reasonable. The capacitors can heal briefly and then start to short. One should also check the rectifier in operation with an oscilloscope as one diode could intermittently short.

VOLTAGE DROP AFTER STR.MAIN FILTER NOT DISCHARGE AND FUSE GONE EVERY TIME. I CHANGE STR & SUPPLY IC.


connect a series lamp for sefty to the monitor. start to disconnect the component from fuse ,line filter, bridge rectifier, filter capacitor, check the voltage at ic 12v also check pulse at str if not then check ic resistors capacitors,and replace if found faulty

After I put a fuse in the player, and plug into wall, the fuse immediately blows.


Hi,
Your fuse blown again because you have a short on the circuit. You may visit my link http://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info.
I've suspect that you have short on rectifier diode/main filter capacitor/regulator IC/transistor. This is quite fixable.
Hope it may help you.
Thanks for using fixya.

Watching program, heard a pop snap and unit lost all power. Even the vizio logo on front panel is dead.


Seems like a filter capacitor has arced and blown a fuse or a couple of fuses. Open the back cover and check the main fuses. If you replace with new fuses and the TV keeps blowing the fuses then replace the bridge rectifier and main filter capacitor. A local repair shop could take care of this very quickly for you. Its not an expensive repair...

Blowing fuse


Check for bad caps or diodes. Look for anything discolored or burned.

if there is no power what you do is re soder the power inlet , if it powers but no light you can bridge the fuse in the inverter its a yellow or orange fuse it should say F1 bridge it and it should work
