hi dave   have tried what you said but no picture on other tv . also there is no sound and the remote control does not work on the tv but have checked it on another tv and is ok . the fault is just as if you had an old signal generator and you had the three primary colour buttons and you were switching from one to another every 2 seconds

Try pressing the menu button on remote. Im sure I posted about the same fault and that cured it.

thanks sinclairtv you were right . i had the remote for the tv and checked that it was transmitting a signal. when i tried another remote and pushed menu button the tv came ok . can only assume that the remote went faulty and sent a jumbled signal to the tv. thanks again
