I replaced shattered Lamp. After plug-in, ok after sw/on cuts out and the PwrLed Blink R/G, Status Blink Red, Pwr Sw out of action remains like that til unplug/plug-in repeat as above. Thanks Padraig

Bad main

If this is what you've got:


"S3" are 3 way switches, black screws are the common or shunt. (Adjust colors of wires to what you have).

You can easily change it to look like this:




All S3s are out. Replace one with an S1 (single pole). The other S3 is now the outlet. Silver screw for neutral gold screw for hot. Outlet is always on, S1 controls both lights.

Please note: There are several ways to wire 2 three way switches (S3) to control a light or two. This is just one with a way to change this method to the way you're look for. Your wiring may not allow you to do this as easily.

Good luck!

sounds like the bulb will not fire up. most likely cause is the bulb needs replacing

Does the light blink or is solid red? If not I would first remove the lamp and examine it to see it is not shattered or damaged inside.

Lamp can look ok and be bad--about only sign is sometimes just before it fails the picture will take longer to come up or is darker.

Lamp life averages 2000 hours or 2 years---less if a generic or NON Sony lamp is used.

When was lamp last replaced and generic or?

Hi scouts692

The Front Panel Header Pin arrangement for this motherboard is unusual, in that the header only appears to have 8 pins in a single column rather 2 parallel columns of 6 Pins with 1 blank, as most conventional motherboards do.

Pin 1 is POWER SWITCH orange or red (PWR SW 1)
Pin 2 is POWER SWITCH white or black (PWR SW 2)
Pin 3 is POWER LAD + (PWR LED -)
Pin 4 is POWER LED - (PWR LED +)
Pin 5 is HARD DRIVE LED - (HD LED -)
Pin 6 is HARD DRIVE LED + (HD LED +)
Pin 7 is RESET SWITCH blue or green (RST SW/RST 1)
Pin 8 is RESET SWITCH white or black (RST SW/RST 2)

Please refer to a PDF of the Motherboard Manual for additional information about the setup of this motherboard (the relevant page for the Front Panel Header is page 17/Section 2-13)

hope this helps.

There are may motherboards, but most have writing on them as to what is suppose to plug where. For example, for the power switch, the lettering might be "Pwr" or "Power" or "Pwr sw". The pins are usually together and should fit the plug on the end of the wire.

The 946 GZT-AM is also used in the Acer Aspire T690, Acer AcerPower FH and Acer AcerPower SK50.

Here is the link to the Service Manual that includes motherboard replacement information including jumper settings:

Hi,

Generaly, the little connectors on the printed side will face the bottom of the case. Also, typically, Black is negative, and white/colour is positive (except on the power sw, it doesn't matter). On the motherboard, where the connectors go, there should be some kind of print saying where to plug them in. (IE, POWER SW, would go into PWR, and HDD LED would go into HDLED and POWER LED would go into PWRLED).


It may look different than this, but generally the same kind of layout, as you can see, it shows the positions, as well as positive and negative.

The fact that the fans are running indicates that your power Sw is connected properly.. Make sure that you didn't accidently pull out/loosen anothe connection to the motherboard/harddrive.

PWR > PWR (aka PWR SW), HDD LED > HDD LED, RST > RST (aka RST SW and Reset)
