My acoustic solutions LCD tv has got power but no picture. i have taken the back off and checked for obvious problems like expanded or leaking capacitors, and cant find any. i have looked online for ages and seems that the most common problem could be the inverter board. does anyone know how to remove the inverter board and how to test it? or any other things that i can try? cheers!! lcd32805hd

there are 2 modules inside tv 1 power 1 tuner lcd's have lamp usually a cfl that lights the screen from power module if tv is under warrnty take it in for servce if not if you are handy you can try to replace module.
if it was working and has sound the tuner more then likely works as audio is coming in. so there is signal.

The solution to Acoustic Solutions problems, such as intermittant power off and flashing blue light is very simple: dump it in the trash. This product has lots of problems which are associated with memory and timing. There is no software update available, its just cheap Chinese ****.

Hi I know this was posted months ago but the answer may help others, I found the capacitor C852 1000Uf ,35v was bulging at the top which is on the power supply board the number C852 is for the acoustic solutions model lcd42762f1080p tv (but this info would apply to most acoustic tvs: WHEN TESTED THE CAPACITOR ON THE ESR METER READ OK, but cos it was bulging at the top I knew it was faulty, it seems that it was breaking down under load hope this help regards celestica

My acoustic solutions lcd26805hd tv has started flickering really badly every time I switch it on. The flickering goes on for about 30 minutes before it calms down. I have checked all the connections at the back of the tv - all ok. This happens whether I watch cable or a dvd.

similar problem but with hum bar on picture , suspect capacitor in power supply ,cannot get circuit diagram

Acoustic Solutions 32 lcd hd Tv screen has green/blue contrast shadows all over the light images on the screen. I have tried changing all the picture setting to no avail.

sounds like either way your power board is bad- do you intend on replacing a component? I would look for Puffy caps- you know- leaking from the top-

This sounds like the unit is expecting component video input (RGB) rather than composite (yel). Check the settings on the set. The power cord makes no difference.
