    Yes +5v present. Still in standby - inverter does not toggle with 'on' switch.

    Thanks - I was afraid that was the case!

    You should also have +5v.

    Did you measure the voltages with the TV on?

On main board (central one covered by heatsink), Measure on cold start voltage at tab of U42 if less than 1.75V replace U42 (You need a decent multimeter for this measurement.).
If you also have/had scrambled picture issues check C414 (470uF16V) near LVDS on main board.
Good luck...

If all the voltages appear normal, I would suspect a main failure because in many LCDs the power supply will power up only after all the voltages circulates through all the circuits and check OK.
You can also have the TV connected to the main power source and press the ON and monitor the voltages at the moment you press the ON button.

My Dad has same problem with Acer AL2671W stuck in standby.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

When i go to turn my tv on all it does is blink that it is in standby mode. The individual i got it from had a surround sound system hooked up to it and i dont know if they have a remote. They are looking....

The first thing you need to do is to check whether your power supply is working well.
To do this, you need to open the back cover of your tv.
You can immediately reach the power supply. Test the power output using a multitester. There must be an output of 5v,12v, and 24v.
24v is for the screen to lit up.
5v is for the the cpu supply.
12v is for the audio...
You can repair the power supply if it is not functioning or buy a new power supply.
To repair the power supply repace the regulator transistor,the opto isolator, the ic that gives the signal to the opto isolator and check for open resistor near the regulators.

I hope this will help.

Acer AL2671W stuck in standby

This too was my problem... ended up googling my heart out trying to find the solution to this problem and found a blog posting

"AL2671W Stuck in Standby Hey - I fixed a TV! It' s been a long time actually since I did something useful for someone. I got asked to look at an Acer AL2671W LCD TV. Bought for about £500 five years ago, and that was cheap then, recently it has regularly refused to come out of standby. Now it is stuck in Standby and won't work. So where do you start? Google of course! Some results showed that this was a common fault on these TV's. One guy in a forum said 'easy fix, replace C280 100uF 16V on the main board'. Good enough of a clue to take a look. You have to firstly remove the SCART socket block before the back will come off and then the inner metal cover over the PSU, audio card and main card as mentioned before. It looks just like a mini ATX card. It is a multi layer, double sided PEC with surface mount and traditional components. Bad news though, no C280 to be found. I buzzed through the front power switch to check it wasn't stuck and traced the cabling to the socket on the main board. Very close by the socket is C380, this is an electrolytic 100uF 16V. Too much of a coincidence? Anyway worth a punt I thought so I changed it for an 100uF 40V I think it was and re-assembled the TV. It worked! the TV now comes out of standby and has been returned to its owners. Result! Posted by andychamb"

I end up finding an old ATI card (since it was unsupported with win7) that had the same value capacitor and replaced C380, located around the centre, bottom left corner (the left one). works like a dream.

turn the power on. to get rid of the red light you need to press the timer/rec button on the remote until it turns off. the red light means it is programed to record.
