Re: Blows fuse

If you disconnect the degaussing coil and the set plays fine, it means one of 2 things is wrong. The degaussing thermistor could be shorted internally. I have seen this happen a few times on those degaussing thermistors that are in the little black boxes with 3 legs. Those boxes actually have 2 thermistors in them, one to do the actual degaussing and another connected directly across the AC to act as a heater for the degaussing thermistor. One of those thermistors could have "flashed over", which would blow the fuse the instant the set it turned on. The only other thing would be the wrong size main fuse. Without a degaussing coil the set probably draws about one amp, but the surge at turn-on with a degaussing coil could be as high as 4 amps. If you have the correct fuse installed and it blows at turn-on, replace the degaussing thermistor.

Re: Blows fuse

Power supply definately. Check for short in bridge retifier. Any Diodes short or regulator bad. start from power cord coming in and check all. Could be anything. Use a meter on continuity and just check across doides when you check and it keeps beeping reverse leads and see if it still beeps constant. That maybe your problem.

It went off on its on and won't come back on. It just popped off while I was watching it.

It likely blew a fuse. However, TVs rarely blow a fuse for no reason. I recommend getting it fixed. You can try a new fuse of the same size, but if it blows, please get it repaired. DO NOT put a larger fuse in - fire hazard. The fuse maybe solder in.

Regarding reset codes

so many people i see are looking for this so called magic reset code and were is the reset button in 99% of cases there is no simple reset button when there is a internal fault a simple factory reset wont work its a dead compoinent it needs to be found and replaced with a new one. the simplest repair fault is a blown fuse yes in this case you can replace it as in some cases the fuse blows due to bad manufacturing but!! when the new fuse is installed turn the power on covering your eyes if it blows imediatly turn the mains power of and have the unit looked by a licenced tech

Blows fuse

You got a short or overload.  Find it and fix it before putting in new fuses or they will blow again.

No power,switched outlets and checked breaker still nothing.Is there an internal fuse?

it out. If the fuses are blown, you may have lost a diode/bridge in the rectifier circuit.

fuses don't just up and blow for no reason.

buzz it out before buying any new fuses.

then try this methed

Check the fuse box or the outlet you are using for power. Easiest way to do that is to plug in a lamp into the same socket the rcvr is plugged into. If no power; reset the house breaker.

Check the power line into the set. Wiggle the cable near the two ends. They rarely go bad in the middle, but the molded ends are always going bad.

: Check for a bad fuse (most modern rcvrs do not use fuses because they have perfected the power protection and management systems to the point that a fuse is redundant. Nonetheless, some manufacturers still use a fuse)

Check the power switch. It can go bad and just won't close the connection so that the set gets power! How to check? Unplug the set totally. Remove the cover. Find the switch. Go to Radio Shack and purchase a small clip lead. Clip the lead across the switch contacts very carefully so as not to short out any other circuits. Then carefully plug the line cord in to see if you now get action.

If the set has an internal power problem, you should still be getting some indication on the front panel (unless the lamp in the standby hole is defective or burnt out).

: If you are certain the set is getting power internally and still totally dead, it is most likely the output transistors in the power stage (mounted to the heatsinks) are all dead. They will need replacing.

Got hit by lighting spike blows fuses when plugged in

The television has problems in the power supply board. The high transient voltages in the spike may have damaged all the board in the unit. This is because of the speed in which it occurs. The Power supply has other safety blow out components in it to stop this damage. If you are lucky the components saved the rest of you television and just blew out the power supply. You will need to have the television tested and see if this is the case. The customer service telephone number is 1-800-631-3811. Give them the model number of you television and ask them for a location of the nearest service center. Call them and ask them how much they charge for estimating repairs for you type of television. They should be able to help you. I hope this information helps you with your problem.

Ac power Symphonic sc309D blows fuse- Dc power ok

The most likely problem is a shorted diode, I suggest replacing them even if they do not test shorted while not under load. If it is not the diode rectifiers, there is probably a resister in the power supply that is shorted, remember also that it can also be both. Lastly, it can be a capacitor within the power supply.

DVD Stopped Working

You can try to place a new fuse in there with the same current and voltage ratings. If the new fuse blows, it means there is a short circuit.

Keeps blowing fuses

When a fuse keeps blowing, that is an indication that some component has failed and the circuit is drawing too much current. Most likely it is a problem in the power supply section or high voltage / flyback section.

Sorry to say, you will need to take it to be serviced.

Please let me know if I can be of further assistance to you.

Good luck!
