It sounds like a faulty voltage regulator or diode on the power supply of the stereo. If you can check these things yourself also check for dry joints before checking diodes and regulator/s. If not trust a competant techmnician. Good luck.

On my kenmore central vac no power unplug unit plug it back green light comes on but try turning vac on green light goes off again .


Please clarify that we are talking about the central vac LED/switch panel panel and plugging it into a 110 V wall receptacle.
If I understand when you unplug from the power source ,then plug back in the green LED comes on, looking normal ? But when you manually activate the switch on the motor housing of the vac itself the vac does not start and the LED goes out, so no green or red LED at that point?
If this is the case , Kenmore CV's built approx 5 years ago (MADE by EUREKA) and prior had a circuit board with attached cord (as opposed to detachable) which was prone to relay failure. There were several symptoms, most common was that the relay on that switch panel /circuit board would fuse on and the vac would continue to run when the hose was detached from the wall.However some I worked on from that era had exactly the same symptom you describe. If your unit is between 5 and 10 years old and this sounds accurate, you can unscrew this curved side panel relay with one philips screw. Inside on the PCB will be an L shaped black or white 24volt relay, generally rated at 10 amps. The replacement board or relay will be rated at least 24V/ 15 amps or more. If you can isolate your motor and test it separtely with a power cord or meter , the realy/board will be the only control componnet left.
If you have a small tipped soldering IRON, not a gun, you can generally find a replacement relay to rebuild the board for about $6 at an electronics parts store. Otherwise you will need to replace the control board itself, anywhere form $45 to $70 plus service call if you have a tech come out to the house, and the tech will just unscrew , detach wires and replace the board, no repair , approx 15 minutes work. This will likely cost over $100.
Please post back with your results

Power LED on but no boot up


it could be your power switch, veriy that it isnt the power supply by

1.) un-plug it from the main board
2.) look at the main board connector(one coming of the power supply)
3.) you should see green wire and next to it a black one
4.) using a paper clip bridge the too wires
5.) if it works proceed to net step if not get a new power supply

to check case switch and board switch

1.) plug in power supply to main board
2.) look at the pins where the power button connects to
3.) using a metal object (blade screw driver) bridge the pins

if the board should start up>
then its your power button on the case that is bad, you can try to repair it, chage it or buy a new case,

if it doesnt work.
1.) ensure that jcms(jumper to flash the bios) is set correctly
2.) unjack each drive one at a time to see if any is causing stalling
3.) get a new main board

Locked sa-ht67


I hope you've already unlocked your DVD player by now, but for all those searching after you, I got the solution from Panasonic.

Make sure the device is on the DVD/CD mode. Press the Stop button on the main unit and the >=10/Enter button on the remote control simultaneously. You will see the word "Initilize" on the device, and at that point it is unlocked.

No power on Hitachi 50UX588


Most likely have a regulator problem. Remove rear cover, look down on the main chassis, turn tv on watch the board to have some colored led's lit, usually a red one and couple of green. If the red is out, its your regulator, if a green one other problems off the circuit with green led are causing the tv not to power up.
