Hi,
It is very difficult to troubleshoot something like this.
It sounds like you opened the Beogram up for some mechanical adjustment (hopefully with the Beogram unplugged).
After your adjustments the Beogram blew a fuse.
Did your adjustment of the platter required you to lower the platter in order to make it flush with the deck surface?
If so then it might now be contacting something that it didn't before (like some wire or component lead).
Perhaps your Beogram had an issue where a wire connection was on the brink of failing and you accidentally helped it along.
I recommend unplugging the Beogram and removing the deck panels and platter.
Also put the platter back on with the deck panels off and manually rotate the platter while looking underneath to see if it is hitting anything.
You can also listen for any sound of the platter hitting something. Look for anything that the platter is coming really close to as it turns.
Then take some good photos of the inside, maybe from different angles and post them here on this Beoword Forum thread.
I have had a few occurrences in the past where other sets of eyes on the problem spot something I missed.
The best way to post several pictures on this forum is to first go to your profile.
On the far right and down a bit on the page is a section called "My Files".
It is a little bit of a learning curve on how that mechanism works but it is pretty easy to master.
You click on the View all files link.
Then on the page the comes up you create a folder name and press Add New Folder.
The folder will appear on the right side under Browse Files.
After that you click on the name of your folder and add images to it.
To add images there is a two-step process.
First you click Choose File. That lets you browse your computer for the image you want to upload.
I recommend taking the time to name each file something meaningful rather than something vague (like IMG01, IMG02, etc.).
It will only let you upload one image at a time unfortunately and you upload the image by pressing Add File (after you have done the browse for file step).
You want the images small enough to upload but not too small where you can't see any detail.
I like to use 2200 x 1800 pixels or 1800 x 1200 pixels.
I know it sounds like a lot of hassle but once you have the images uploaded under your own folder you can use the little filmstrip icon on these forum post pages to select and add several pictures to the post...albeit just one at a time.
The interface is kind of clunky but the result is good.
...and it will let everyone here see what you are seeing.
