I recently bought a Philips portable DVD player with dual lcd screens. After using it two times on a trip to cornwall I've noticed that the second lcd screen model PD7032/05 (SLAVE DUAL SCREEN ) does not show an image anymore, however there is sound coming from the speakers still....First I thought it might be a problem with the AV cable and bought a new one, but I still seem to the same problem with the second screen. Does anyone know what the problem could be? Pls advise me on what I should do? Thanks
