The mainboard problem.. no display.... how to fix it? tq

CPU Cache test error. Failing mainboard or more likely a failing CPU. Not something you can fix without replacing the mainboard or CPU.

hi. change your display setting on computer. go to desktop properties and change your display setting

my printer can not work because at display print queue there are warning "user intervention required", I has been trying with reset manual and sofware (Ip tool) but did not still working.
so what the best solution for fix it ?

If it's still in warranty, then Acer will fix it free of charge.

If not in warranty, disconnecting and reconnecting the cable that joins the display to the mainboard may fix it. It may be a dirty connection, a dead inverter board, or even dead backlight (incorporated into the lcd panel itself) or the entire lcd could be shot. It could also be the onboard video chip. Also try connecting the netbook to an external monitor. If you power the netbook on with an external monitor connected, it should light up the external monitor. Also, it may not be the display...... Try removing and reseating the ram. Try just one ram chip if there is more than one. The unit may just also be dead (mainboard). Try the warranty route first. Acer also has a flat fee they charge to do a mainboard in Canada ($199). Call Acer first.

Hope this helps! Let me know how you make out.

have to get leak fixed fault will show up every time fluid level is low -but trans-gearbox can overheat and burn up which will b more costly

I agree, applying pressure should (key word) not effect the display if it's the mainboard. Either the technician that replaced the screen was not fully qualified for his job, or he just wanted to do a quick fix to get some money. Here are a few suggestions:

1) Go to ebay or craigslist and get the same one for a cheaper price.

2) Send it back again and tell them that you've already invested a great deal of money into this system and refuse to pay for a faulty console.

3) Do a pressure check. Find that spot that fixed it and a way to consecutively fix the problem by pushing it in that spot so that when you send it back, you can show them that it is in fact the display.

4) There is a small (i forget the exact term) ribbon of wires connecting the display to the mainboard that could be the problem; hence they said it is the mainboard. You'd be better off buying another system before you throw away your money into this one.

If you wind up getting another one, invest in a rubber skin or a hard-shell skin so that if it is dropped again, there should be no problem.

Sounds like either a driver problem or a defective graphics chip. Is this a new or older notebook? Determine your graphics manufacturer and try downloading their latest driver for your video graphics software or hardware driver.

If it is a defective chip, you will need to contact the notebook manufacturer to get repair service. If the notebook is less than a year old you should be able to get the service for free. If you have an extended warranty then it should cover your situation.

Hope this helps.

Replace all electrolytic capacitors in power supply section on mainboard. caused by poor quality lower voltage caps being used in powersupply. Problem will reoccur every 2 to 3 years if 105oC caps are not used. If mainboard is replaced with new mainboard problem will reoccur within same timeframe. Fix old mainboard using higher voltage and higher temp caps and problem will be gone for good.

You can't fix it. I'm afraid it's a dead board.

erch.
