There's some good LCD news though-- I found a seller who's trickling out small numbers of refurbished HV121P01-100 screens, and unlike all the others I've sampled in the past several years, these have so far been excellent. Yes, they're rebuilt, but they appear to use entirely genuine, model-appropriate parts. I have no idea if these are parts from B-grade panels being reassembled into new screens or what, but the results are NOS visual quality.
There's a 'downside': he actually seals the panels together with black RTV silicone. If you want to open the panel up to do further surgery, you can't. Or rather, with a thin spudger, a ton of patience and very very steady hands you can, but slip once and you'll crack the matrix. I did open some up to have a detailed look--- Yup! All genuine inside!
If you *don't* have any reason to open the screen up, the black silicone is a good idea-- it keeps grit out, and prevents the dreaded 'white spots' from ever developing. I've considered building screens this way myself, so I actually approve.
I'm importing a few of these for conversion to LED. If you want one, contact me about it. If you want to order directly yourself, it's item #710816705 on AliExpress. I have no idea how many per month he can actually make, or if the quality is going to hold up, but so far, so good!
