Acoustic Solutions LCD32NK750HD 32in after around 5 minutes the the picture suffers from horizontal lines, split screen sound is ok throughout.I have taken the back off and having only ever serviced crt tv's was rather surprised how little in there.However it seemed a multi connector from the main board to the screen board was causing the problem so made it secure and it worked for a week but the problem is now back again.Any help would be greatly appreciated.I know from experience about these unbranded/rebadged model I've got no chance of getting a service manual so hopefully someone has come across this type of fault before.Thanks all,great site too I have some manuals I will upload soon,they're a bit old but well someone might need them.
