Please Help! Samsung pn42c450b1d

by jen_ff / August 14, 2010 2:56 PM PDT


I just bought my tv a week ago. Excited to get it onto the TV mounting stand, I went to the hardware store and bought what i thought were the right bolts (TV stand did not come with the bolts). I then tried to screw in the wrong size bolts to secure my Samsung pn42c450b1d plasma tv onto the tv mounting bracket. I took a break because I couldn't get the bolts to go down any further.

I came back three hours later to remove the bolts. I noticed that one of the bolts was hot. I then noticed that inside one of the holes in the TV where i tried to screw in the bolt it seemed to be cracked inside.

Did I just ruin my tv by trying to screw in the wrong size bolts?
What should I do?
Please help... i just got my tv and I hope I didn't ruin it. Sad

Thank you.

Unfortunately, based on the pictures, it would seem that the holes are pretty stripped. The size of all VESA-specific mounting bolts should usually be between M-4 and M-10, and for plasmas, the sizes are M-8's. That bolt is clearly not compliant with the VESA standard.

If the TV still powers on, you may not have "ruined" it (although, it'd be difficult to know why the bolt got hot, and what the effects of that might be long-term), but I wouldn't suggest mounting the TV on the wall at this point with the support of stripped threads. Either an exchange from a sympathetic retailer, or a service call to replace the back panel of the TV would give hope of having the TV mounted on the wall.

I had the same issue
by wtrhzrd / August 23, 2010 4:47 AM PDT

I just bought the same TV this week and purchased a universal wall mount kit. It came with 7 different size bolts, none of which were the right size for this tv. The kit included bolts up to M6, and after researching a little bit, I found that this tv uses M8 (they are metric if that helps). I actually had a hard time finding M8 size bolts, even Home depot only had up to M6 in the cross-tip (phillips) style screws. I wound up bying a hex head bolt M8.

To jen_ff: I agree with other poster. If the TV is still working, you're probably fine except that you've probably stripped the mounting holes out, and probably have a crack of hole inside the mounting holes. They looked like threaded inserts to me, so you might be able to research and see if they can be removed and replaced with new threaded inserts so you could still mount it. Otherwise you may be stuck just using the stand that came with the TV.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
