You have a bad ceramic capacitor in the high voltage section of your TV. They are usually in parallel with other identical caps located beside a transformer. Notice that your TV has three of these circuits for each color gun. The best way to check these capacitors is to pull one leg of the caps out of the circuit board then test them with a Fluke Digital MM. Set your meter to capacitance and make sure that is on auto range. If one of these caps has a very low farad reading than all the rest this is your problem cap. What is happening is that when this cap is trying to build up to a certain voltage it cant. This is in turn causes a system overload and then your TV shuts down

the problem is simple. you need to first change the fan for the processor. The pc goes off since the fan to cool the processor is faulty.........just to prevent damage to the processor. get a correct model, normally by checking the spare part number on the fan and try googling it up on the net. need me know if you need assistance in buying one.

TV shuts off after 5 seconds Magnavox CT270MW8


Open TV and notice if the VCR cartridge jumps (jitters) back and forth when you plug the TV in before it shuts down. If it does, there is a good chance you will have to replace the VCR mech on this unit (available from Andrews Electronics and maybe MCM electronics for $40-$50). This is a common problem on this unit. I work in a TV repair shop and see a lot of these come in for this reason.

try this, press and hold the tv button on your remote about 3 sec. light should stay on, then enter code, if it's a good entry light should shut off, then try to turn tv off. make sure your tv is on before trying this.

Toshiba A60 shuts down in 3 seconds


Bios may be set wrong(fix by restoring default settings)

memory may be damaged(replace if true)

battery may be low and system shuts itself off(make sure battery is charged)

Drivers may be wrong(replace drivers in safe-mode)

Motherboard or other devices inside laptop may be loose and/or shorting.(Go to local computer fix-it shop or (open up laptop and check for loose connections which may void warranty.))

My guess is your bios needs resetting

Hope I am a help.

White Screen w/ White Lines, Sound On, Turns off after 2 or 3 secs.


Hi If you mean thin white lines, this is is an indication of a problem in the Horizontal Drive ckt. most likely the Damper Diode has opened or shorted, this would cause the visual symptom and then the set would shut down, unfortunately this is a problem best left to a qualified technician to repair, hope this helps.
