Hi Carlos, error code 3 & 4 is caused by faulty RAM (Memory modules) installed in the PC. You could try the following to resolve the issue:

1. Open up the computer cover
2. Locate the memory module(s)
3. Remove them memory module(s)
4. Use a can of compressed air or spray contact cleaner onto the center of the DIMM connectors to clean all the contacts. Do NOT use a normal brush to clear dust away. Wait for 5minutes for the contact cleaner to dry.
5. Reseat the memory module(s)
6. Turn on the computer and check if codes 3 & 4 still light up. If it does not, it should boot into the Operating System.
7. If codes 3 & 4 continues to light up, you will need to run a memory diagnostic test to determine which of the memory module is faulty.

Why are frigdaire front loader all leg ligts on right side blinks and beeps all the time

Thanks for your inquiry, Barbara Williams!

I understand that the lights on your Frigidaire washer are blinking and beeping. It sounds like your washer is providing a set of error codes. Your control panel may need to be replaced. I would recommend contacting a professional technician for proper diagnosis to be completed to avoid any unnecessary part purchases. Hope this is helpful. -Matt

SOUND GOES IN AND OUT.CAN'T TURN IT DOWN WHEN ON

Try a "REBOOT"

Reset, Initialization &
Option Menu
Front Panel Reset & Initialization
Many customer generated symptoms, intermittent symptoms
or symptoms that cannot be duplicated can be resolved
by performing resets or initialization from the front
panel. To avoid making nuisance service calls that may
not be covered under the warranty, ask the customer to
perform the following functions before going to their
home.
The most common are:
ā€¢ System Reset (Re-boot)
ā€¢ A/V Reset (Resets Customer Audio/Video
Settings)
ā€¢ Initialization (Resets all customer options,
settings and menu items)
Use the Front Panel Guide as a reference to quickly
perform the desired function. Note: Button location may
differ by model.
The Reset - Initialization Guide details all resets and initialization
functions.

After pushing start, lid locking light flashes, clicks like it is locking but is not locked and nothing happens but it keeps clicking

Sounds like the lid lock itself is bad, be sure to check the connections at the control board. There should be a tech sheet inside the front panel towards the top left. This can help you check the error codes and wiring diagrams.

It was working fine until yesterday. It shut itself off. I powered it back on and befor the screen could come back on it shut itself off. I checked cables and uplugged it for 24 hours. The first time...

Hi Daniel,

Please check if you can access the "error code operational check" to narrow down where the fault came from.
How to enter to error code operational check.
Note : The TV must be in shutdown and not have been switched off. When the TV is switched off, the error code automatically resets to 12 (no error).
Press the buttons on the front panel "Input/Device" and "Menu" at the same time and hold it for 5 sec, activate the error code mode. The LED light will flashes denoting a two digit error code.
Example : if the error code is 22, the led will flash two times pause and then flash two times and will repeat the error code for five times.

If you can't access the error code operational check , please let me know the exact pattern of the flashes of the led light and its color. Check if it will continually flashes green to give you the caused of the symptoms and best solution.

Good luck and take care.

E 000732-0001 IN CANON iRC 3200 .

Here are some possible solutions
getfile.asp?rid=1258 March 3, 2009 getfile.asp?rid=3215 Product : imageRUNNER C3200 / 2620 / 3220 Title : E732 and E733 are Displayed, when Copying off the Glass or when using the DADF
Error :
Error codes of E732 and E733 are displayed, when copying off the glass or when using the DADF. The Control Panel would go blank and the processing data light would continue to blink. After a few minutes in this state; the copier was rebooted and the codes would resolve themselves, but would eventually return.

Workaround :
First, try reseating all the connectors to the Reader Controller, Interface PCB, and DDI-S PCB. Next,
check for proper voltage to all three boards.
In this case, a defective DC Fuse PCB caused the error codes. An intermittent loss of voltage to the Reader Unit caused the machine to code out.

Note:
The part number for the DC Fuse PCB is FG3-3020-020.

2003 GMC Intermittent Starting Problem

Check the other end of battery cables, may have good connection at battery but not at starter or ground. (Always check ground first, often a source of problems.)

Next time it happens, try hooking up jumper cables and see if the intrument panel lights up.

Also, check for loose fuse, not properly seated fuse. And cables to fuse block. (That model may have more than one fuse block)

Replace Transfer Roller

In the Phaser 6250 Color Laser Printer Service Manual (which I had to have emailed to me from my toner supplier since it is not available to the general public) I went to Chapter 6 - Error Messages and Codes. I had to reboot the printer. Here is the procedure.

Entering by rebooting the printer:

1. Turn the printer power OFF
2. Hold down the Back and Information buttons simutaneously and turn the printer
back on.
3. Continue to hold the buttons until the following message is displayed on the front
panel: Service Diagnostics V#.##, Initializing ....., and then release the buttons.
4. The front panel displays the Service Diagnostics Menu.

On the display is a menu. Find Transfer Roller. Press enter on this menu where it says Toner Waste (Not Full). Back out of the menu.

All of a sudden the machine came to life. You may have to turn off the printer and turn it back on again.

Good Luck
