Grateful if someone can help please. I can get sound but no picture on AV1 from my video or DVD players. The TV is a Bush OnDigital integrated digital TV. Ondigital is a company in receivership, so no assistance is available. The video is an AIWA HV-FX7700K. The aerial connects to ANTENNA IN on the AIWA. A cable leads from the R/F OUT on the AIWA to the ANTENNA IN on the TV. On the TV a short lead connects the R/F IN and R/F OUT sockets. Finally, a scart lead connects the AIWA to the TV. These settings worked fine until my son's friend plugged in a PS2 playstation to the TV with a scart lead. Now I can't manage to retrieve the situation. The TV uses UHF channel 69. THe TV standard can be either RGB or composite. The AIWA output channel is RF C67. I can only get sound from the DVD player too, which indicates that something in the TV needs re-tuning. Any ideas would help. Give me a PC any day!
