Dream Authentics LCD Claims

Don't worry, in 5 years you can buy 300dpi OLED foil, and you can heat-wrap it on your old 19 inch tube. Your Geforce 580GTX6 takes care of the pacman-tridot pattern emulation with realistic afterglow and the massive 512Gb Solid-State VRAM takes care of the usage-history to present an accurate burn-in image.

I've had several people ask me to fix their LCDs that had perfectly working backlights.  The power supplies crap out and so do the controller boards - just like any other mass produced complex electronic device.  The power supplies are usually replaceable but the damn SMD controllers are pretty much death sentences if anything on it dies.

Swapping surface mount components isn't nearly as hard as people seem to think it is.  The challenge is usually just buying the darned things in small quantity.  However, that's becoming quite a problem on the "digital" CRT sets, too.  If the micro dies, you can't get one with the right firmware on it.

Really, the reason these aren't repairable is because it isn't worth it to do so.  Making the device easier to repair would inflate the price by ~10-25%, and prices are already so low that it isn't worth paying a repairman for his/her time, so why not shave the extra 10-25% off and just make replacement cost less.  Besides, when it dies, you'll be able to buy something 10 times better for 1/10th the price.

As for killing an LCD by playing games on it, you won't.  One of the nice things about LCDs is that pretty much nothing kills them except time.

Of course, this doesn't mean LCDs are good for gaming.  I like my (very high end) LCD PC monitor just fine, but for gaming I use a Sony GDM-FW900 or a real arcade monitor (CRT, of course).  I do have one cabinet with a Plasma on it (and yes, it's very burned), but that's just because you can't buy 40" widescreen CRTs.

That's pretty much where I was going.  Unless you can swap a replacement board in, and those tend to go OOP within 12 months of production, it's just not worth the repair cost most of the time now.  Sad, really, as it produces even more toxic electronic trash than before.

Heh.  Another big challenge is just identifying the parts.  Not such a big deal if you happen to have a schematic, but that's often very difficult to come by for some of these "here today, gone tomorrow" boards you find in LCD panels.

Small parts often means cryptic labeling.
