Going from Betson monitor to a tv - help

[nycjsw]

Ok, so my Betson monitor crapped out after only 4 years.  I had a 27" Panasonic Super Flat TV that fit in my Mame Room Cabinet (must < 27" wide to fit in cabinet).  The Panasonic only had a S-Video hookup and I bought a VGA-S-Video adapter from S-Video dot com after I read about them on this forum. The picture wasn't that great and was kind of fuzzy. 

On Craigslist I tried to find a better TV.  Luck would have it a friend of mine was getting rid of his 27" Sony Wega with component inputs.  It was too wide but I figured I would cut the sides with my Dewalt saw. Like an idiot when I took off the back cover to see what I would be cutting I failed to remove ONE SCREW  Naturally this screw was the one holding the component video jacks in place and it broke them off the circuit board. Well the S-Video on this TV looked pretty good. So I went with it and put it in the arcade cabinet. I soon found out that the TV was shorting out after a while (hours to minutes).  I figured that I learned my lesson about the screw so I went back on Craiglist and saw the EXACT TV for sale on their for $70.  I bought it, tested it and cut the sides again.  After I cut the side and put it in the arcade cabinet I noticed the upper part of the picture looks a bit distorted and the component video inputs no longer work   

My question is does anyone have any tips to what I'm trying to do?  There are circuit boards on the bottom back of the set so I guess the TV could be flexing a bit putting stress on these circuit boards??? It is also leaning back a bit on an angle so this would put more stress on the back of the TV.  With the sides being cut I the back off the case is not nearly as solid. I also used a dolly to transport the TV after cutting it.  The dolly has a 8" x 16" plate and I don't know if that mght have also messed up the TV?

Thanks for all your help.  When the arcade is working it is a lot of fun. I have Mame running on it.

Have you tried to have your betson monitor fixed? Any local tv or game repair shop can probably handle it cheaply.

Yeah, I dropped it off at a place that had good reviews.  I gave them the service manual.  They tried a few things including ordering some parts but in the end I junked it.  There was a $40 evaluation fee that I paid.

I guess my main question was about cutting the plastic around a tv. I don't want to totally decase the TV b/c of the danger but wondered if this is why people decase it.  It seems that trimming the sides has rendered at least 1 tv and maybe 2 nonfunctional.  Not taking a screw out was my screw up.
