Re: JVC LS-300 wobbly screen

Great video, Duncan!

After my screen fix without Loctite, the screen went wobbly again in only about a month. I went back inside and fixed it properly with some Threadlocker Red on the two LCD panel screws. I took still photos along the way, they will compliment your steps nicely.

Re: JVC LS-300 wobbly screen

To Duncan and Steve:

As an additional thought to go with the screw thread-locker on the two LCD screws, IF there is enough screw thread available perhaps an “external tooth” or “star” lock washer could be added.

I couldn’t tell if there is a lock washer under the screw, but even if there was, I think a star lock washer would give better tooth to prevent screw turning than the traditional lock washer. If doing this again, it would be worth asking someone knowledgeable about washers if this would be reasonable.

In the past when working on electronics I remember seeing some red stuff, sort of like fingernail polish, dobbed on the side of a screw where it would touch the board (or whatever). Don’t know if this was to help prevent the screw becoming loose or as a method to detect is someone tinkered with it.

Anyway, you guys did really good! Be sure to let us know how the fix-its held up.

Re: JVC LS-300 wobbly screen


Since last week I'm having wobbly screen. I've followed the pics, unscrewd the 2 screws and added some loctite before screwing them back, but the door is still wobbly. Any hints?

Duncan, any chance of watching your video (youtube link doesn't work) to see if I'm doing something wrong?

Thanks in advance?
