Hi scanorama99

There were several threads in the (now) Archived Forum 2, where there was talk about this.

See here:

/forum/general-discussion-and-questions/beovision-avant-55-mk1-screen-fault#post-2105888

 

The Willy, who is mentioned there, is not on Beoworld.

However, he is active in the Beotalk YT show - you may be able to contact him via the show or his social media.

But…..maybe another member will be able to provide more details.

It does not seem to be that hard, if you have some technical skills.

If you PM me I'll pass along Willie's e-mail address, and you can ask him to post here, maybe?  Or if you have the stomach for it, review old BeoTalk casts at chipmunk-speed on YouTube (pre-#150), or maybe e-mail its host (also PM) to ask which one.

What I recall was that Willie pulled the USB voltage off the interior of the connector to a fan on the case back or bottom, not board mounted -- which would draw air past the offending video engine chip.  He wanted some brand fan (Noctua?), but had to go with something smaller (and/or thinner?) because the full sized one wouldn't fit.  Then it was too loud, so he soldered in a couple resistors to tap the lower voltage.  Sorry I don't have that TV so I didn't really follow where exactly he mounted it.

Or maybe you could join next Sunday's BeoTalk chat and ask (or throw them a couple bucks of so-called "superchat") and we can all listen to the details again.  Good luck!

Thanks for the replies. Eventually the tv refused to boot up. It always got stuck at a gray static fuzzy screen even after having it plugged out from the power supply for days.
I had to wait for a very expensive mainboard fix for about 4 months. Now I can see tv again.
