Acer AT2001 20 in. EDTV-Ready LCD Television - Answered Questions & Fixed issues
Tv suddenly stopped working. plugged it into
Hello,
When you stay the TV stopped working, do you mean it doesn't turn on any more? If yes, your TV has developed a power problem.
We don't stay in the same area, so I wouldn't know precisely where you can get it repaired. But you could read through the below and see if you can fix this yourself, or ask a family or friend that has the ability to help you out or assist you as two good heads are better than one.
The
issue you describe is consistent with a power supply board issue. This
is the board where the AC goes to. This problem may have occurred as a
result of irregular power supply, or excess power supply or power surge.
The
TV is receiving current but cannot circulate or transfer the current to
other necessary part of the TV because of the defective power supply
board. You might be lucky it's just a blow fuse. Also a defective
transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But
more often bad capacitors causes problem on the power supply board. I
do not think the power board needs replacement, rather those defective
capacitors is causing this issue. Open unit up and take a look at the
power supply board.You will probably see one or more electrolytic filter
capacitors that are bulged up in the top-not perfectly flat like the
others.
The value of these capacitors will be different, most
likely they will be somewhere around-820 to 2200uF/25 V( or /10V
sometimes)
You can replace them with same values but I would
recommend the voltage rating to be higher(like 35V for an original 25V)
for reliability purposes.
What happens is,these bulged top
capacitors will cause a low and unfiltered DC voltage=main board will
malfunction(the relay will keep clicking until the caps are holding
enough charge to bring the voltage up over a threshold point).
You
can buy these capacitors at any Fry's or Radioshack store or you can
order them online at vendors like "mcmelectronics.com"(look for
electrolytic capacitors). After replacing these capacitor(capacitors)
most likely the normal operation will be restored. Or you can by a
refurbished complete power board to save you some stress.
Note:
There may be also some other causes for this symptom ,like a defective T
con board ,or main board,but the bulged top capacitors are the most
common cause for this issue.
If you don't know about TV
repairers, take the TV to the nearest repairman to fix the fault for
you. Also, note that TV stores a lot of current, so wait a while before
opening the TV back cover.
I hope this helps.
Regards.
Need a new remote
You can contact the makers website or it may be much easier and cheaper to find a universal remote that lists your tv as a controlable device
Problems with Acer AT2001 20 in.
Hi,
you need to go to:- My computer/control panel/display
you should be then into the display settings panel. at the top of the panel, select settings. and you should set:- colour quality Highest 32 Bit ( or whatever the highest is )
Then Screen resolution ( bottom left ) should now be 800-600 to 1024x768 or similar.
Whichever is best for your monitor.
if you can,t acheive this. you need to re-install any drivers for your graphics card or onboard vga.
Thankyou for using Fixya.

Acer AT2001 cannot use as monitor
I currently own an Acer AT2001 21 inch Television/Monitor. The refresh rate on your computer should be set to 60Hertz. You can change this setting by right clicking the desktop, click properties, click settings, click advanced, click adapter, click list all modes, click 800by600 at 60Hertz. The screen resolution will not go above 800by600. Note; Initialize these settings with an old crt monitor and then plug in the Acer.
Screen turnning yellow
cleaning was not only the one needed but maintence as well! some of the components might be getting disconnected inside!
send it to a service center... it won't cost you much since is it still working!
Acer PD116Pd Projector no powerup .
Hi,
Please start by switching the outlet that you use to power your projector. If you're not currently plugging the projector into an outlet but using a power strip, you can test that the power strip is still functioning by using it with other items. Thank you.
What is my remote control number for Acer brand At3235b TV?
Statistical Process Control TrainingAll Acer TV models use the universal Remote Control code NEC 18E7, which most of universal Remote Controls can use. We recommend using the search function, available on most universal remote controls, to find the compatible code for your Acer TV.
Have blue line across my acer one tablet Oly a month old why is this happening
Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
