The ratings will be stammped on the board next to the fuse if it doesnt say then its a 125V fuse amperage will be stamped on the fuse itself if not stamped on the circuit board next to the fuse.

What causes a blown fuse in tv samsung

Usually in a Cathode Ray Tube Television a blown fuse is either something is wrong in the high voltage power supply section or the flyback transformer is bad, or a bad horozontil output transistor.

Heard a pop noise from LG 60PC1D tv, tv shut off and now the picture looks like a negative kind of...what is wrong?

Capacitor on the power supply popped and it is not allowing the proper voltage to be reached to the main board. This is messing up your picture. I would repair it before you create more damage from the blown capacitor on the power supply.

Please rate if this helped :)

I have a LG MU-42PZ90V that was given to me. I found one bad fuse. When you turn the power on it flickers from orange to green then shuts off. I was just checking a few things and noticed that it has...


On this model you must replace the power supply if the blown fuse was on the power supply, but the main cause for LG failure is the Y_Substain Board assembly. When measureing the voltage of the Large Capacitors, this is the primary side to the main supply, you must measure the caps form hot ground, on the AC side of the Standby transformer for correct Voltage, 66V is to low. Look at the side of the Lrg Capacitors for their voltage ratings, the Supply voltage to these should be some what near this voltage but never higher. The Y_Substain board is to the left of the power supply standing in back of the unit. Its possible its just the Y_Board gone bad, but in my experience the you should replace them both.

I have a 42" lg plamsa tv the screen went black and still had sound.. found a blown fuse on the board to the right of the power board, when i replaced the fuse,it will power up and then 5 seconds later i...

The fuse you have replaced would have been on the sustain board, now that it clicks indicates a problem either with the control board or the sustain board. You would need to disconnect the connector from the power board to the Y-sustain board (left of power board) to check if the Vs & Va voltages are present, if so then the power supply will be working ok & the problem will be with the previously mention boards. There is the possibility that the plasma display screen could also be faulty.

Picture gone on an LG 42pc1dv-ec plasma. Sound OK, inputs OK. Vs fuse blown on y-sus board. Replaced fuse but still no pic. Checked d.c voltages from PSU. When switched on from cold Vs>300 and Va>80....

Your Vs voltage is high, check if the heatsinks on the Z-sustain board are getting hot after a short time, if so replace the Z-sustain board. If not, dis-connect the Vs & Va plug connection to the Y-sustain & check if the voltages are normal (185V & 80V). If they are then your fault will be in the Y-sustain board. There is a possibility the control board (sits below the power supply) could also be a problem as it is not able to initiate the control to the sustain boards.

Plasma television with sound and no picture

You will most likely have a fault with the Y or Z- Sustain board. It might be one of the fuses has blown on the board. You would need to check this & check if you are getting your Vs & Va voltage supplies to these boards. There are other possibilities, it may be advisible to call your service repair centre.
