Old unit? possible innacurate grounding. miswired speakers. stay color code correct if possible. take 9v battery,touch wires until you get desired scraping sound without radio on or c/d running, (how to distinguish lfront, rfront ,lrear ,rrear locations. If you dont have matching color coding from deck harness to existing wires, you have to do 9v trick to find and isolate sp wires. Yellow or red can be power, not necessarily red. black obviously ground, blue is remote power for power antenna or for powering up a power amp..will pick my sons brain if you need more or detailed info.
Hello Phenom, Hi.... to properly run/test a motherboard, you need to make sure this parts are good with no doubt functioning. 1. the power supply, 2. Memory, 3. keyboard, 4. Processor with FAN 5. PC speaker(built on-board or the thumb speaker) and 6. monitor
How to test. First remove all motherboard connections. Now reconnect the following.
1. make sure that the power supply 20/24 pin is connected properly to the motherboard (and please test this power supply before making connections. To test independently short green wire to ground and plug the unit. you should see the fan spin) 2. make sure that the 4 pin 12volt power connector is also plug in nice and tight. 3. clean the memory slot using a clean paint brush and the module (DDR/2) terminals (the contacts) using an eraser, 4. connect the keyboard, 5. make sure there is a PC speaker connected. 6. connect the power switch of the front panel, 7. Connect a monitor on the VGA port 8. Power on the PC. 8. Look at the keyboard lights 3 LED momentarily. num lock + caps lock + scroll lock and after several seconds 1 LED light, num lock only. If you reach this part you should also hear a beep. then the POST will appear. If you don't reach this part, start again from the top. do this several times. Still no response? you motherboard is bad.
Hi, If you are using normal 2.1 channel speakers, That has a green jack cable coming from the speakers. Connect the same to the green round jack at the back of the system tower or in the front on the headphone jack. In case you can give the model number for the speaker . It would be easier to tell how to connect them. If you are using a laptop , connect them to the headphone jack either on the left or the right side.
This is the "protect" mode -- the unit has detected a short circuit in the speaker output and has shut down to keep from burning out the amp.
Remove the speaker wires, then reconnect one at a time. If the LED starts flashing again before you've connected any wires, then the problem is within the receiver. If it starts flashing again when you connect a particular speaker, then the problem is in the wiring to that speaker or the speaker itself.
Jags are definitely a pure breed. The new radio most likely has writing on the wires that tell where they are to be connected to. I take that back. I just checked the wiring of an older model JVC unit and there or not listings. If your radios doesn't have writing just remember Orange(or yellow) is illumination, and it goes to the fuse block; red is power, going to the fuse block; the big black one is the ant.; the little one is the ground to the chassis. The others are speakers. Connect them to the colors they are closely resembling in your Jag. Connect the power and turn on your radio. You can reconnect the lines to the correct speaker by checking each speaker. hope this helps.
Hi Paul, see page 8 number 15 for location. Than see page 19, System Panel Header in your manual. The basic wire color's for positive are red, blue, green & can also be light blue, light green, light red. Negative wires are usually white or black. Case wire colors do vary from case to case. To see pin one shown on page 19, (positive + for hard drive led = HDLED+). Bottom row farthest pin to the left of set. Pin two is above pin one. Pin two is, PLED+ (known as power led). Pin 3 is to the right of pin one & is HDLED- (Hard drive led, negative). Pin 4 is above pin 3 & is also PLED-, (Negative for power led). ECT!
If your new case has an internal speaker (Used for P.O.S.T, power on self test). This would connect to, Chassis Speaker Header located on page 8, number 16. Again, normally only two wires are used across the 4-pin connector. (One at each end of the connector).
