Check out the regulators and horizontal output first, Then capacitors in the power supply. It could be a few things but those are first to check. If you would like I can send you a link where to purchase the service manual.
Keep me updated.
Thanks,
Lee

Kenwood no sound


Just had the same thing happen to my new pioneer system. My truck battery died because I was jamming to the new installation, and the system just suddenly turned off. I charged the battery and the unit came on all the lights menus and displays worked like normal but there was no sound coming from the speakers. I checked all the fuses in the truck but none were burnt out. So I remembered there was a fuse on the back if the unit so I had to pull the unit back out. I checked the fuse and it was fine. I unplugged the wiring harness from the unit, plugged it back in and IT WORKED so I'm not sure exactly what was wrong with it, but I suspect when I unplugged the harness it reset the unit. So maybe this will work for your installation as well. Not exactly a high tech answer but maybe it will help ya! Good luck

Gigaset a420 has stopped making or receiving calls


You mean unplugged it from the power outlet or the RG45 wall jack? OK so if the battery is fine and you unplugged the power from the source, then the issue is with either the cord itself or the charging unit. Just because the little red light comes on does not mean it is working properly. Put a multi-meter on the charging tabs to double check for continuity. Sometimes and as weird as this sounds, it just takes unplugging a nearly spent power pack/inverter to finish the job so to speak. If you unplugged it from the RG45 then you need to look at the pins in the RG45 wall jack to see if you inadvertently bent one out of shape.Phone won't work if there's no signal. Wish I could help more. Good luck with that issue.

Deivers tail light/brake light do not work..reverse works..when i lock my car the lights flash except for that one and the drivers light..headlights work fine though.drivers headlight bulb connector looks...


Could be a broken wire at the socket. Sounds like a burnt bulb also. Sometimes a burnt bulb will do the same thing as you are describing. Once you get this fixed, all should work. If flashing to quickly, replace the flasher stat unit!

My keurig b70 coffee maker says prime. sounds like the pump works for awhile then stops. prime lights up on the screen and doesnt let me do anything else why


Mine would brew the first cup fine, then the pump would run but would not draw water from the reservoir. I turn it off, turn it back on it would draw water for one cup then would not draw water again. I unplugged it waited 30 seconds and plugged it back in, assuming that would reset the electronics. It worked fine following the PDPU (power down, power up) procedure. Simply turning it off will NOT reset the processor, you MUST unplug the unit. Remember to wait 30 seconds or so prior to plugging the unit back in.

My western digital 500gb hard disk light is not on. It was working so fine. I'm not able to understand the problem


hi

i have the same unit ..eventually if the unit is not unplugged and plugged in in sequence as i describe here, the power module will be expended.
when disconnecting , you have to unplug AFTER you (via software, S/W) disconnect from the ICON found at the bottom right corner of the computer screen , After disconnecting via s/w, unplug the USB cable, then the power cord.

when reconnecting, plug in the power cord, wait 30 seconds, then plug the USB cable in .

this should alleviate the issue at hand. if the unit does not function, then the power module inside the hard disk drive housing is no longer working

i hope this helps

send me 4 thumbs up please.

There is no power to the TV. It was working fine. Turned it off and the next day it wouldn't come back on. Have checked all the connections, power source, and followed manuals procedure for unplugging,...


this can be many thing that cause this. first off did you lose power that night? if you did most like your power supply inside crashed. does any lights flash or turn on? if they do this can be a number of things. if a light comes on then your bulb may have finally burnt out. (like if you have no screen but your hearing some sound turning it on and off.(threw the speakers a hum) try turning the volume up to test this. test this first and i will be glad to walk you threw the rest. i hope i can help you.

Same Problem - Suddenly Died ~2yrs old, very light use.


Probably a fuse inside the unit. Can be caused by overheating or by door switches not working properly.

Pink screen


When the "pink screen" happens on my Polaroid FLM-1911 TV, I unplug the power cord from the back of the unit, wait 30 seconds, and replug it. This fixes the problem.
