Hello and thanks for your question. I look forward to assisting you today with the best answer possible.
I am extremely sorry for the delay in follow up.
Could you please tell me more about the error sign which you received?
When you plug the unit, does the red and the green lights blink for a while and then the green light stays on but the screen doesn't go on ?
No problem, just post a message when you're ready.
The error indicates the main board of your unit has gone bad and needs repair.
Before I tell you how to proceed with the repair, could you please tell me how old is this unit?
Do you have electronics repair experience?
The unit needs to be disassembled completely and the main board needs to diagnosed for faulty capacitors and other chips.
I would not suggest you walk you through repair this as this unit is just over a year and there is a high probability that the unit's manufacturer will provide a replacement.
I have seen many customers of mine having successfully replaced the unit.
Please let me know what you want to do.
