I am hoping that the corporate brain of MHFun can help. After seeing the Akura 20" TV/DVD combo in Hughes I rushed out and bought one. I had reviously had a 19" model but the dvd was nackered and they did not have another as I has brought the last one. The 19" model worked fine on 12v but the 20" does not. When connecting the 20" model to 12v it powers up but the screen is in black and white and the tuner will not decode the signal. Measuring the tip of the cord shows 12.8v. The ac/dc converter suppile with the set shows 13.4v. If I connect ehu and switch on the onboard battery charger then the TV works fine in the 12v socket. If I connect the TV via an inverter then the MH control panel shows a drain on the battery of 5.8 amp, The inverter drains 0.9A itself, so the TV is draining at about 5.0A. I realy wanted to use the TV direct from the battery if possible, has anyone any ideas? Could there be a large enough drop in the 12v wiring to prevent the TV from operating?
