Title: Samsung TV QA75Q7FNAW Service Manual
Post by: EEVblog on December 02, 2024, 02:09:06 am

I'm looking for a service manual for a dumpster Samsung 75" QA75Q7FNAW TV
Or really, just advice on how to get the rear panel off so I can try and put 350V DV up it's clacker to see if the panel is working or not.
No obvious screws holding the back panel on, and a spudger around the outside lifts it off a bit , but there seem to be no catches at all.
So just seeing if anyone know before I go medieval on it's arse. Thanks.

Different model but, in my case wire pull didn't work.

Can't find the exact video with fullest explanation, but this one is the closest to how it works: https://youtu.be/g0ojfT2rJtQ?si=NB2cQrZdMSg6ET52&t=113

The unit was most likely dumped due to burned backlight leds. Which, of course, burn together with the diffuser.
