On the bottom board is an electrolytic capacitor (C975) that might have failed. The top will be convex (bulged out). Since this is in the power supply, the unit will not work. Also: Check resistor R4843 and diode D4709 for charring on the board (indicates extreme heat). I have been trying to find the value of that resistor and so far no luck. Replacing the cap brought the set to life, but there is still a problem since the sound will cut off momentarily randomly. The receiver unit is at fault, not the sub unit. So I could use some help as well!! Good luck.

I do not have the remote to my lg bluetooth soundbar subwofer anymore and they arent pairing can you help please


Press and hold PAIRING in the back of subwoofer for more than 5 sec,
until LED on subwoofer blinks red and green alternating.

Unplug the power cord of the soundbar and the wireless subwoofer.
Connect then again after the LED of the main unit and the wireless subwoofer fully turned off.

I am unable to power on this TV through the remote or TV power button. Do not get a green light for power. Should I look for replacing a power supply cord or the power unit within the TV?


Hi Liz, You are not getting The green light means either the power ie AC is not reaching the TV or the power supply section inside the TV has broken down. Your guess is right about the power cord and the power unit within the TV.The Problem will be there within your guess. But I think you will need the help of a good technician to isolate the fault and rectify it. Good luck.

Magnavox 37MF23ID, would not turn on. Power button only blinks (green light). We have switched power cords and nothing happens. No picture, no sound.


if the power light comes on but the screen stays black, then your TV might be on the wrong input Channel. for example: you switch inputs when you play games or watch dvds vs. watching regular tv. Try to change the input

Wiring diagrams for clarion dxz535 car stereo


Here's how it goes:
Speaker wires:
grey=right front pos.
grey/black=right front neg.
white=left front pos.
white/black=left front neg.
violet=right rear pos.
violet/black=right rear neg.
green=left rear pos.
green/black=left rear neg.
red=12 volt switched power source
yellow=12 volt constant power source (direct to battery)
black=chassis ground
orange/white=illumination (switched source,not to head light switch)
blue/white=amp turn on lead (to remote turn on lead of amp)
blue=auto antenna (switched power source)
brown=phone mute lead (to cell phone mute lead)
RCA connector leads:
grey lead:
red=right front
white=left front
black lead:
red=right rear/right rear subwoofer
white=left rear/left rear subwoofer
(connect to external amp)
red lead:
red=right aux input
white=left aux input
(connect to external unit)
green lead:
red=right dual zone output
white=left dual zone output
(connect to wireless head phones)
That should be all there is. on the yellow that goes direct to the battery you need to use an inline fuse holder with 30 amp fuse.

Ps3 shut off and doesnt have power


send it in for repair is you still have warranty.
If not you can purchase a power supply for about 40 bucks plus shipping and change it yourself (it is pretty easy). This will solve your problem if there is no lights whatsoever (not the green-yellow-red light).
If interested in a working power supply contact me at bubulica2000@yahoo.com.
Thanks

Can't get sound from the wireless subwoofer


There are 2 things you can try, first ensure that the digital transmitter is fully inserted into the slot of the main unit. Secondly do you have any other wireless devices near such as cordless phone or wireless network equipment? See page 5 of the installation manual as per this picture.......
