Power supply transistor transistor no. C4237 replaced 4 times. each replacement didnot sustain for a week. which transistor can i use instead.


I have worked to repair a few of these. When the transistor is burned, you most likely have a bad flyback transformer and bad picture tube. In this case you replaced this (transistor) component four times. This TV cannot be saved. Thanks for asking.

I have a panasonic th-42px80u, i turned it on and there was a pop and a flash from the back of the tv. It will not power up and have no red light. ive taken apart and inspected power supply board for burn...


Look for a fried (possibly exploded) transistor or diode on the power supply board. In particular, look at the transistor mounted on a heat sink (metal radiator block) between the fuse and the largest transformer on the board. It may also have a damaged regulator chip driving it. Modern TV sets operated by remote controls generally have the power supply split into two sections - standby and main. Your problem is most likely in the main section.

A voltage sniffer won't tell you much - most sets have power right up to the fuse on the power supply board. If the fuse is blown, don't bother replacing it until you find out what blew it - you'll just waste another fuse. I generally start by doing ohmmeter checks (power disconnected!) on the diodes and transistors - anything reading less than 1 Ohm is probably fried or is being shorted through a transformer winding by another fried component. Other readings must be interpreted according to the circuit design.

Because you can switch the inputs between digital and analog. You can switch TV and DBS and also Tape and MD.

JVCAV-N2043TV,Horiontal Output Transistor burns out everytime if fix a new one


Hi There,

The Hor Output transistor is connected to the Line Output Transformer. This transfromer provides a lot of voltages around your TV set but includes the very high voltage to the Picture tube...

These transformers are specially tuned to resonate at a certain frequency,
The Hor output transistor needs to match this frequency....so if the wiring inside the transformer is shorted by "just a bit" the picture will be visible but the transistor is struggling to match the transformer impedance,from the mismatched tuning...so the transistor draws more current from the power supply.. runs hot then burns out...

Usually manufacturers provide a Trip circuit that detects that an overload on the power supply is occuring and cuts the power to the Line output stage ...this is usually detected by a clicking sound within the power supply its called hiccuping.

If some one has altered the correct setting on the power trip circuit then the next thing that happens is the Transistor goes Blooooey like in your case.....

So to save you a lot of money replacing the output transistor
please replace the output transfromer as well next time...

But please... please... re-check the power supply trip circuit to save you a lot more expense in the future....

Best Regards From YUBEUT

JVC TH-A10 Won't TUrn on...


Unplug the JVC and the subwoofer from that outlet. Then, plug them back to a different outlet (where power is constant and not interupted by any switch.) Hope this helps
