1st make sure the fuse is good under seat near battery !! then take out one spark plug and rest it near metal (don't hold it !! ) and crank engine over (key on) do u see a blue spark on end ?? if so you have fire , if not you need to go further to see why , connectors on plugs I find are the \\biggest problem on bikes now , seems they don't make em water proof !! and everyone tries to avoid it but they allways do get caught out in the rain sometime !! the rain doesn't effect em right away takes a few days then the little pins in there get what looks like "baby powder" on them that's the bad stuff it all needs to come off !! bike don't run till there clean and bright again !!
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.
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.
These TV's are prone to power supply failure. I can fix the power supply on this TV for approx $100 +s/h.... Contact me and all you have to do is remove the power supply and send it to me and I will repair it with high quality parts. Reinstall and you TV will be good as new...
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
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.
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.
