Hello and welcome to JustAnswer. I look forward to assisting you today with the best answer possible.


Sorry to hear about your issue.

We'll do multiple troubleshooting steps. Please be patient and don't rate my service until we have finished everything.

Unplug the power cord and disconnect the audio-video cable plugs from the unit. Then pick up the unit and turn it upside down, gently tilting the component side to side and front to back.

Please turn the unit right-side up and plug in the power cord only, then press the "Open/Close" button.

Tell me if it makes any difference to your problem.

I am currently at work so not with my unit.

I will try your suggestion when I get home tonight and if it does not work I will bring the unit to work with me tomorrow OK

Thanks for replying,

No problem we'll continue at your convenience.

I tried what you suggested with NO success , so I assume the DVD is not offcentre in the drive.

Still no lights come up to show power is on.

Does the unit have a fuse or something ??

Expert:  Md. Sadique replied 1 year ago.
Is the unit completely dead ?No signs of life.
Customer: replied 1 year ago.

When you hold the Open / Close button down , nothing happens , when you let it go the little green light flicks on and the message comes up

"Please F71 or perhaps F21 then nothing green light does NOT stay on

Expert:  Md. Sadique replied 1 year ago.
Please repeat the above step and tell me the exact error code.

Open F76 is What comes up in the window

Expert:  Md. Sadique replied 1 year ago.
I am sorry to say, your unit is going into protection mode.It is a problem with the power supply of your unit.
Expert:  Md. Sadique replied 1 year ago.
As of first step disconnect all the speakers & other I/O devices, with only power connected from your unit.Then check if it still shows the f76 error message.
Customer: replied 1 year ago.

The unit has NOTHING connected to it, so not sure what to do next??

Expert:  Md. Sadique replied 1 year ago.
It could either be a blown power supply or a board and it needs to be replaced.Look for either a pulled white wire, or check any white wires coming off the transformer where they plug into the board. There could be a cold solder joint which needs to be resoldered or a faulty capacitor in the power supply, or near the protection relay.
Expert:  Md. Sadique replied 1 year ago.
Are you comfortable working with electronics circuitry ? Do you know how to use a DMM and a soldering iron ?
Expert:  Md. Sadique replied 1 year ago.
We have to diagnose the receiver by visually inspecting the large filter capacitors for bulges, leaking at the base or the solder joints. Also, you can test the output power transistors by verifying that only one leg of them are common to ground. If more than one leg is to ground then it verifies that the transistor is shorted.
Expert:  Md. Sadique replied 1 year ago.
In most cases the output transistors attached to the heat sink are shorted.This way you will be able to know which one is at fault and then replace it accordingly. If you feel you cannot do it then the best bet would be to take it to a local repair shop to repair it at a less cost. If your unit is under extended warranty scheme then take it to the manufacturer to repair it for free.
Customer: replied 1 year ago.

No it looks like it will be cheaper to replace the unit.

I am not familiar with fault finding electronics so was looking for confirmation as to suitability for repair.

Eg , cost of parts $80-00 , Labour $120-00 = $200 total repair cost , not worth it ??

Expert:  Md. Sadique replied 1 year ago.
Yes, absolutely its not worth repairing if you're going to take external help.
