Acoustic solutions lcd26nk750hd. after about 5-10 mins of tv being on picture flikers off and left with sound,have tried loads of scart cables

The TV electronics for the picture may have failed. Do you get any picture ever, like when you turn it on, or when you connect a DVD to it?
If you do then replace the scart cable with a good known brand. Cheap scart cables often do not have all the pins connected up.

Go to Monoprice.com or TigerDirect.com and look for conversion cables that will work for you.

ok make sure all the cables are plugged in properly and into the correct slot, Check all the channels and make sure that it is not on AV If this doesn't work try new cables or scart leads, if you use a scart lead plug it into a differnt location E.G Some T.V's Have more than one scart lead socket

How have you connected the VCR..vis Scart or UHF cable?
Has your tv got more than 1 scart socket if connected this way.If so, have you tried using a different scart inputon the tv?
Has the tv got picture and sound when vcr is not connected?
All these answers help with the diagnosis :)

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.

how many cables shud link up to the tv with the acoustic solution model AS134?i have the colour coded pins plugged in to the speakers left,right,back left,back right and center which plug in to the subwoofer box.how ever i then only have 1 cable left which has a red pin and a white pin that i assume go into the AUX left and right pin ports?the cable then splits into another 2 red and white pins.do these pins plug into the left and right output on the tv?am i missing any cables?help would be appreciated.

I have recently brought the same TV and had the same problem but I've mangaed to find a soultion.

The automatic setting for Blu Ray on PS3 is Full HD (1080p) but the Acoustic Solutions TV is HD ready (720p). For PS3 games it will automattically change settings for you to 720p. This is why this works straight away but Blu Ray doesn't.

Solution

You need to plug in your PS3 using the scart contection, then on the ps3 menu go to settings > display settings > HDMI. You will then need to attach the HDMI cable and manually set up
HDMI by checking the 720p option and deselect 1080p.

That should then play Blu Rays too. You don't lose too much quality as 720p works nearly as well as 1080p on smaller TVs.

Sounds like you either have a bad card or a bad HDMI cable. Scarts are not the most dependable when it come to HD imaging there is alot of converting going on espically if the TV isnt NTSC standard to begin.
