Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review your details here.

Hello Brian,

could you please try disconnecting all the speakers and connections so the main unit is hooked up to the mains power only, then tell me if it will turn on and stay on in that state?

Hello Nathan , thank you for your follow up . Sadly i have not had any luck with my unit .Even replaced the remote with new batteries . When i hold down the yellow blue and the ok button together the unit displays 00 RET . What does that mean ??? Kind regards Brian
Electronics Technician: Nathan, Engineer replied 8 months ago

Thank you for trying, Brian.

Unfortunately, the issues you are experiencing are symptomatic of an internal hardware defect, meaning a faulty control board, though there are many possible failure points. This issue could be a manufacturing defect, but is also often caused by a power event (shock/surge, prolonged over/under voltage condition, etc).
This could also be the result of age related wear and tear; as a 2012 model, that type of failure wouldn’t be surprising. This unit is at the end of its service life at this point.
There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm an internal hardware failure.
This is something that would require repairs to correct; though repairs for these units just isn't feasible. There are no parts available for them any longer and labor alone would be 2-3 times the cost of a new system.
I can help you with finding a repair shop, or recommending replacement options, if desired.
My apologies for the news,

Nathan
