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.

My 39 inch tv fuse blown constantly


Either a short or incorrect fuse being used--fuses have become specialized beyond amperage and voltage ratings--a lot are special fuses and or either a slow blow or even a thermal type fuse.

If not a fuse issue, look for a short in the power supply or wherever that fuse is located.

My emerson model lc320em2f keeps blowing the fuse on the circuit board what can cause this


Check the main power supply regulator board. It will have shorted component/s. That is why, the fuse blows up. In most cases, the components to these type of TVs are vary difficult to get from open electronic spare part market. So it will be best to replace the power supply board as card basis, rather than trying to get it repaired.

Arcam alpha 8 amp keeps blowing fuses


When the fuses keep blowing suspect an overload in the power supply or on the Main Power Amp board. Chances are that a semiconductor has developed a short and is acting like it was just a piece of wire. The main suspects are power transistors. These can be tested with an Ohm Meter, even in circuit! For when the test probes are applied to each terminal, the meter will act just like you were touching the probes together.

Main fuse blown on CT-32G11 32" Panasonic TV, Replacement fuses continue to blow.


If the main fuse keeps blowing, check the horizontal output transistor for a shorted condition and diodes in that section as well.
