Here is a link to the service manual for your device.

There is a limit of 2 free downloads per day on the website and as I have reached my download limit for today I cannot download the manual to look at it and see if I can help.

However you can download it and hopefully if you can read a circuit diagram it may help you to find the problem. If not post another comment tomorrow and I will get back to you sometime soon.

To download the file when the sentence underneath the Document preview box changes from This file is downloadable free of charge: ... processing to This file is downloadable free of charge: Get Manual, click on the Get Manual. This is the download link.
