TV Sparks inside case

When I power up this tv it sparks near what looks like the power supply. Bright blue power! Looks cool at night but not as good as the Olympics coverage after 3 times.

I think I would turn it off and unplug it. You could get an estimate on reparing the power supply cord or whatever the problem is or the TV maybe ready for replacement.

Why does tractor runs fine til it warms up then stalls and wont restart til cools down


Check to see if you still get spark at the spark plug wire when this happens, common problem is a "Hot Coil" the coil windings breakdown under high heat and causes a stall until it cools down, just pull a plug wire place it near engine ground with a small gap see if there is a bright blue spark when you crank the engine over. If no spark, or it is weak orange spark..let it cool down then try it again if it then sparks bright blue you have a coil issue and it needs replaced. I have also had key switches over heat and stall the engine as well check your wiring connections on the key switch if its burnt looking there is also a problem.

My 48 inch plasma screen goes black whenever something im watching goes bright, like a white flash on a show will make the screen go black and audio still on. turn the t.v. off then on and it works again...


The internal fan can fail.

Before you invest money call on a TV repair man,place a small fan near the power supply. (within 3 inch from the power cord or the nearest vent from the power cord)

This will keep the power supply cool and keep the therm protection circuit from tripping,

When you has time,inspect the internal fan for movement.

Power supply for dmtech wt20xt lcd tv


I have DMtech 20" with intergrated DVD and had the same problem- blue light lit on power switch but no response on power up.
I noticed that when the power cord was unplugged from the back of the TV the green LED on the power supply would brighten and consequently dim when plugged back in. Sometimes the blue light on the power switch would strobe very quickly but you had to look carfully for this.
I repeatedly unplugged the DIN type power plug from the back of the TV untill the green light on the power supply stayed a constant bright and there was no strobing on the blue light on the front of the TV, when I powered the TV on at this point the button worked again and the tv powered up with the silly tune then life in the screen. I did have to do this a good few times (I'm tenacious) but it did work!!!!!
Hope this helps someone else, cheers.

No Power


you need to isolate the failure.
first, measure the voltage (called B+ usually) on the biggest elec. capacitor in the power supply. This should be about 130-160 Vdc.
If this isn't here, then the problem is in the power input circuit.
If there, then the high-voltage supply is down. If the set is anywhere near 10 years old, then replace the flyback transformer and its transistor (H.O.T.) and go from there.
The worst case is that a power surge or something has killed the TV's brain chip and you'll have to do a board replacement.
Let me know.

Phillips 50p8341 Projection tv no picture


Looks like the blue crt is bad and may have killed the main power board that has the high voltage supply.
A new crt is almost $400 and my distributer shows the power supply as no longer available, but may be able to get it somewhere else. Plus you need the service manual to realign and converge everything (hope you didn't mess this up too bad). Really need to find a good rear projection tech to do all this, but may not be worth it.

Broken plasma


You will need service on that tv. I suspect a bad power supply or possibly the y or z board. Do you see delay in the picture when it changes?
