How to fix Acer AL2671W LCD TV that won’t turn on or stuck in standby…
A customer gave me one of these after the local electronics repair guy couldn’t fix it.
The problem with this one was that once it was warm it would work OK, but from cold you either couldn’t turn it on at all, or it would turn on then become non-responsive to button presses.
My first instinct was to replace all caps on the power board, but that didn’t make any difference. So, after reading http://www.fixya.com/support/t668400-acer_al2671w_stuck_in_standby I tried replacing C380 as well, and the problem appears solved.
C380 is right next to a heatsink solder-to-PCB interface of a nearby component, so it probably has its life shortened due to heat.
Here’s a photo of C380 – I didn’t have a 100uF around, so gave it a 220uF instead.
Cheers, Mike.
PS – As a side note, the power cable to the main board has multiple 12 and 5V rails. The brown wire remains hot 5V all the time, the others only when powered on.
Thank you!!
I acquired a TV with this problem and your blog was spot on. Now works perfectly thanks so much

I did not really believe in it. I had been battling to turn the TV on for a few years now and it was getting worse and worse. I was sometime playing with the master switch and the front button for 15 minutes or more before I was able to turn the TV on. I changed that C380 capacitor and it now works fine.

I think replacing that part will fix it but can’t promise it.
