Thanks Ian for the info.

Unfortunately DVD unit has got problem either in power supply board which is not providing required volts to other circuit boards or main processor board isn't working for some reason and causing this issue.
It requires further trouble shooting in unit with voltmeter to determine defective board to get it replaced if it is still available as sound system is bit old model.
If you have no plan to repair it yourself then local repair shop will do this job but it may cost good money like 100 to 150 Pounds depends on what board is bad in unit and if still available.
I would recommend to invest that amount on new sound system instead of repairing this old unit.
I trust my input will help you out. Please feel free to respond if you have any additional questions.
A positive rating to answer would be greatly appreciated!
Regards,

Shahid.
