Then teh power light slashes abootu every 10 to 15 seconds. I have tried to unplug the unit and plug it back in and try the sequence all over again but to no avail. IS their a reset switch or fuse that needs to be replaced.

    The solution offered was too general. Where is the power supply fuse? What kind of fuse is needed? How do I get to the power supply. Also it is a CT36HL43 not a 38 as I earlier posted.

This suggestion is only if yr panasonic is a Cathod Ray Tube kind. most times what causes such problems could be as a result of a dead Horizontal Transistor thats located around the lines transformer. but losing a CRT could be disastrouse i suggest also u give it to an expert other wise open the case of the CRT use a screw driver to discharge all power capacitors by bridging the 2 legs together. then carefully remove the yoke from the CRT.
NOTE:
to identify the Horizontal Transistor, it is normally attached to a heat sink and close to the lines transformer and is usually the biggest Transistor around the lines transformer.

To identify the lines transformer, the thick cable with a cap thats removed from the yoke is directly connected to the lines transformer

Transistors r electronic components that has three legs(pin) normally label Q with some smaller label like B(base), E(emiter), C(collector)
so try it out
that is if itsd a CRT.
hopes this helps
thank u

It must be power supply board problem. If you are not familiar with such repairs have a person to help you inspect board for bad electrolytic capacitors blown resistances etc. and replace if needed. In general electrolytic capacitors over 100V must be replaced.
Insert also your model no at link below to look for a service manual.

If this is a CRT TV, then I'd say that you probably have a failing flyback, or an issue with the power board. If it is an LCD or Plasma, the it is most likely the power board.

However, it is very difficult to say precisely, without conducting tests on the TV. Probably just replacing the power board might resolve this issue, however, I do recommend consulting a TV repairman, as they would be in the best position to diagnose the problem and provide a fix.

In any case, I wouldn't recommending opening up the set if you have no prior experience, as it can be dangerous.

If your TV is still under warranty, its best to contact the shop or the manufacturer in this regard..

BenQ 8700 Won't Power On


As far as the projector goes, the ac power supply is fused with probably no more than a 7 amp fuse, that would blow before your breaker would if the problem were in the projector. The only thing that could case the breaker to trip would be a defective AC outlet socket or your cord for the projector is bad. I have seen cases where cat's have chewed though the cord and shorted it out and triped a breaker, outside of that if the projector is bad now then your thought of sending to the manufacturer is the best one.

Hitachi Rear Projection TV won't operate aftter circuit breaker was tripped.


Well pard, obviously that power glitch buggered up something. That tv is pretty complicated. The main microprocessor could be outta commision. The power supply appears to be ok, at least partially. I could get in there with a meter and scope and figger it out. But you probably need to have a reputable shop look at it. BTW that's a good set and worth keeping going.

Here is the proceedure to replace the lamp and reset the lamp hours.
Lamp Replacement Procedure:
1. Press the POWER button to turn off the power.
2. Wait for about 1 minute until the cooling fan stops.

The lamp cooling fan will continue to operate for about 1

Cord from the outlet until the fan has stopped. Avoid
interrupting the power by using circuit breakers or switchable

Note:
Please wait more than one hour before replacing the lamp.

After the POWER button is turned OFF, and during the
first minute of the normal cooling fan operation, press
the VOLUME UP button on the unit and CH UP key on
the remote at the same time for more than 5 seconds.
The cooling fan operates for about 10 minutes. (LAMP

will flash red for 10 minutes.)
4. Remove the Front Cover Unit from the latches.
5. Turn the Knob to the left.
6. Pull the Lamp Cover out.

Have a ws-42413 mitsubishi TV


This behavior could be an indicator of power supply problems or abnormal current drain from elsewhere in the set.
Modern supplies are, by design, able to shut down if voltage or currents aren't within the design limits of the circuits they are servicing.
Without some hands-on it is not possible to isolate the problem unless one of the forums deals with a series fault.
If the set had a reset button, it would be located on the outside of it where the user could reset it.
The reset buttons one finds on some sets is nothing other than a very cheap kind of thermal circuit breaker that trips when current is above its limit.
These are kind of prone to failure themselves.
