I just got a 50hdx82 from craigslist, and it needs help. I've posted a short video here of what it looks like, because I'm not even sure I can accurately describe it:
Basically, the screen seems to shake from left to right so bad that you can't see the picture. When I first turned it on, the menu was affected too (so bad you couldn't read the menu items) but after the tv warmed up, the menu became readable, and the screen is certainly better than it was when it was first turned on (some type of warm-up effect). I did try the touchfocus, and the horizontal lines are clear (and drift downward), where the vertical lines are very squiggly (and drift left).
I appreciate any advice, and if this is a common problem, any pointers to sites that have pictures or directions on how to fix this particular problem (like this one I found while searching for information; it isn't the same problem, but with this much detail I'd definitely try a DIY fix- http://cmpalmer.blogspot.com/2006/11/fixing-my-own-tv-part-ii.html)
It is the Hyper board gone bad. There 11 10uf 16v cap's that go bad. They are very small surface mount type 4mm in size. They are cheap but hard to solder in. There is a guy on ebay who is rebuilding them for $75. Just search this part number: MVPU14 that is the hyper board.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).
click here to download the app (for users in the US for now) and get all the help you need. goodluck!

Tip: The max point reward for answering a question is 15.
I am sure there is a better person out there to help you but if "they" are blocking you then you may need to contact them, your IP could have been used in some scam, as a very guarded oldie that place looks to be a great playground for hackers and scammers.
It may be worth checking your device for any nasties, also settings may have been changed in it so you are not recognised.
Thats my knowledge limit sorry to say........
Craigslist provides a function where you can renew your post, to move it to the top of the list, but you have to wait at least 48 hours from the original time of posting. Here is the page which gives instructions on that: http://www.craigslist.org/about/help/repost .
It sounds as if they store information on deleted posts on their servers, so you may not be able to re-post more often than every two days. You can also contact Craigslist with your question using their help desk discussion forum - https://forums.craigslist.org/?forumID=9 - or the feedback page - craigslist.org/feedback (but put the address for your location before craigslist such as sfbay, then a period, then the address I just listed).
All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.
Common Problem #1) Convergence has gone out
Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.
This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.
Common Symptoms include....
Screen looks 3D
Colors don't line up
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed or warped.
TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy
Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.
