The display comes up with UnCal when the ambient temp drops below say 15 degrees celsius then when it warms up it works normally.


I'd try to locate the problem using freeze mist. Spray each component for a second or two to see if the unit acts up. Repeat with each component until you find the one that is causing the problem.

Display light out on boston acoustic duo-I plus


In my case the blue LEDs were dead. It is pretty difficult to replace them by new SMD-LEDs but I managed it. Open the front, take out the board from the front part (5 screws). On one side of the LCD-screen you can see a white stripe with 3 resistors 101 (100 ohms). You must free this stripe form the plastic body on the left and right side (eg. by soldering iron). Solder out this stripe, on the other side you will find 3 very small smd-leds. Break them out and solder 3 new leds onto the board (left side = K). For control you can put 3 Volts to the Anode (A=+) and the Kathode (K=-) of this stripeboard before fixing it on the frontboard by soldering.

9VJL3 front panel


Do not have the Front Panel header pinout.

Do have;

Take an LED (Light), with two wires, and check the pins with it.
There is a Top row of pins, and a Bottom row.

Touch the first two pins in the Top row, left side. Does it light up?
No? Go to the next two pins. No? Go to the next two pins.

Keep going until the Power Supply comes on. (It is a BRIEF touch. The Power On switch is a Momentary Contact Switch )
Now you have the Power On switch pins.

LED light blinks? You have the Harddrive activity LED. (Light)
LED light stays on? You have the Power On LED. (Light)
Computer restarts? The Restart switch pins.

Short something out? NOPE. You can't hurt a thing using this method.

4 of those pins are for an internal speaker. (To hear BIOS Beep Codes with)

That's 12 of those 18 pins. (Probably less. It is two rows of 9 pins, that are stated for the Front Panel header)
4 of those pins probably won't be used.
You won't be using IR. (Infra Remote) (Only uses 2 pins, though)

Most of the time with an 18-pin Front Panel header;

Top Row:
Starting at Left side, going towards Right;
Pins 2, 4, 6, 8, 10, 12, 14, 16, and 18.
May be a pin missing in this row, or two.

Borrom row:
Starting at Left side, going towards Right;
Pins 1, 3, 5, 7, 9, 11, 13, 15, 17, and 19.
Same thing here. May be 1 or 2 pins missing.

Pins 2 and 4 are usually for the Power On LED. (Light Emitting Diode)
Pins 6 and 8 - Power On switch.
Pins 10, 12, 14, and 16 may be for the Internal speaker.
Pins 18, and 20 are usually not used.

Pin 1 and 3 for the HarDDrive activity LED.
Pins 5 and 7 for the Reset switch.

Pin 9 is usually reserved for the factory, and is a 5 Volt test point.
Pins 11, 13, 15, 17 for speaker; or not used. Same with pin 19.

(So speaker pins may be top row, or bottom row. Dunno )

Another thing. This motherboard is old enough to be using a 3 wire LED, or dual color; for the Power On LED.
LED usually had the colors Green and Yellow.
Yellow for 'Normal' mode, Green for 'Turbo' mode.

(Which is a bunch of cr@p.
Green LED, or Turbo Mode; was actually NORMAL.
Normal mode was the computer operating BELOW the Normal mode)

So pins 2, 4, and 6, may be for a 3 wire Power On LED.
