Is good you have checked the main fuse and is good,what that means is you have voltage going in but you loose it down the line,if you have no indication of power(no lights ,no clicks) you need to check if you have the 5 volts that power the microprocessor witch is the brain and it uses 5 volts to aperate,the 5 volts come from a 12 volt regulator so you will have 12 volts in one side and 5 volts in the other,if you have lights or clicks when you push the power button you have 5 volts but one of the other voltages is missing,Check the horizontal output transistor for a short,if it is bad it likely cooked the safety resistor that gives him the voltage.If you are familiar with tv service you have a place to start but if you are not too familiar be safe and call for assistance from a servicer.Let us know if you need more information or how it went.

Why won't my TV turn back on even manually??

total dead usually means the fuse---unplug the set for safety and remove back cover---follow power cord just inside and you will find the fuse in a snap in holder--check to see if bad.............if good let me know and I will try to assist you.

RCA BIG SCREEN TV WONT TURN ON HELP !!!!!!!!!!!!

Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.

If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.

Usually when devices power themselves off like that, there's something wrong...

I hope this helps :) Good luck!

Best Regards,

James

Philips 47PFL7422 Flat Screen no power

Check the main fuse
If that is ok look for puffed up capacitors on the power supply
Check the 1000ufd @ 35v change them to 1000uf @ 50volts

Good luck

Hi there!

Where you saw the Arcing, check closer to see wether the components are not loose on the board. You may only have to resolder the joints and problem solved. If the arcing takes place towards the tube, then you have a more serious fault. Thus involving High Tension, so I would not advise trying to repair that area if you are not familiar with TV repairs. Please unplug set before commencing any work. Regards and good luck, JUS004

LCD TV WONT POWER ON

A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.

First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.

If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.
