My Acer TCO03- power button is just blinking but no picture display


Blow hot air into the back with a hair dryer before trying to start it.

(not kidding)

if that works, one of the capacitors on the power board went bad.

even if that does NOT work, one of the capacitors on the power board went bad.

It is ALWAYS one of the capacitors on the power supply gone bad.

Being unplugged for a few weeks - as you stated - drained it of "juice", and it just cr*pped out. It was going to fail soon, in any event.

Fixing it can cost you less than a dollar, if you Google for information.

Best of luck!

Monitor does awake from sleep mode


You need to check the inverter fuse, transistors, caps, solder joints. Please see my pictures here to get some ideas so you will know what to look for inside.

Computer went off and starts anymore. unless wen I unplug a cable


Hi Leslie,
It could be your power supply is dead. The 4 cable wire is the 12v axillary power supply for the graphics. When unplugged you will get no graphics when plugged in nothing will work if that rail of the power supply is faulty. Hank

Unable to strart windows


Clear Real Time Clock (RTC) RAM by way of the jumper. This jumper allows you to clear the RTC RAM in CMOS. To clear RTC RAM :
  1. Turn off the computer and unplug the power cord.
  2. Open the chassis.
  3. Remove the on-board battery.
  4. Move the jumper cap from pins 1-2 (default) to pins 2-3 for about 5-10 seconds, then move the cap back to pins 1-2.
  5. Reinstall the battery.
  6. Plug the power cord and turn on the computer.
  7. Hold down the <DEL> key during the boot process and enter BIOS setup to re-enter data.
  8. Start setup again and make sure your setup disc is not corrupted.

Front seat is not moving


The d.c.m module( your seat switch) controls the window operation and seat operation. It also relays signals to other control modules on the data system. does any other components not work? You can unplug certain connecter but not the main can connecter to the data bus. For the hell of it check the fuses. I beleive your schematic is located in the left side of the dash(behind plastic cover) visible when door is open. If not refer to owner's manual where the fuse schemstic is. good luck

What else to check?


Check your fuse for the transmission if it is an automatic. It may have went into a limp mode without power to the soleniods as such all you will have is 2nd gear and reverse. Also the PRNDL switch may not be getting power too, so it would give you trouble starting.

My computer speakers just went silent in the middle of a song


Do the speakers have power? Check the fuse.

Where are you plugging your headphones?
Where are the speakers connected? Is it the same jack as the headphones?

Have you tried plugging the speakers into the headphone jack vs the soundcard?

No power


Check your power cord very carefully....especially the plug ins (square box)....could be the power supply itself. Regarding fuses; You can't see it inside the computer it is an electronic component. Got to go to store
