Hitachi 51UWX20B still going... fingers crossed

My old Hitachi 51UWX20B is still kicking. I've had it since 2008 when my wife bought it off CL for $115. It has worked fine until the last year. The green lamp starting intermittently dropping out, and it had gotten worse in the last week. Two days ago the green dropped out and didn't come back. I thought she was a goner.

I recalled reading that you can often fix this problem by disconnecting the CDT driver board and cleaning the contacts, so I revisited this thread to look for tips. I didn't find any good Hitachi-specific videos or links, but I did take off the grill and access panel to get a look at the lower end of the CRT assemblies. In doing so, I had to move a big old stereo speaker my wife, in a fit of room rearrangement, had parked in front of the TV, with the bass speaker (and its big magnet) nearest to the green CRT driver. I tried blowing the dust off the driver cards and ran a Magic Focus to no avail. I was hesitant to disconnect the driver from the CRT due to shock risk, so I closed her back up and kept searching for info on discharging.

Last night the green was still off. After watching a WWI documentary (mostly black and white footage), I switched to a different channel and was pleased to find the green was back! I then ran a Magic Focus, and the picture was better than I ever remember. I switched to BBC America and watched several episodes of Planet Earth, loving the detail.

I assume the speaker magnets were messing with the convergence, and the effects (other than the green dropout) were subtle and gradual enough to write off as "old age". I still need to clean the optical surfaces and blow the dust out of the cabinet.

Anyone else enjoying a Hitachi CRT RPTV?

I have two 65813. One i purchased in 2005 and another i got free from craigslist because it had the blinking green light. Fixed that one with instructions from here. Love them! Going strong. Hope they last forever!

I'm glad that some people have been able to keep their RPTVs going, but my Mitsubishi 65315 recently refused to power on, and I don't remotely have the knowledge or expertise to fix it. Thirteen and a half years was a decent run for a TV. I also had a CRT front projector for a long time, but there comes a point where you just have to let go. The Mits went to the recycler yesterday. Time to switch to a 75 inch Roku TV with 4k, loads of apps, HDR, etc. Will it lack some of the things I like about CRT? Probably, but I'll only use it for non critical viewing of TV shows and football games. The critical viewing is reserved for the theater room. Adios, Mits. You gave me some nice viewing pleasure.

Honestly...I don't think you will miss one second of it, after you set up your 75" HDR/4K set. After dialing down/out the screen door effect (motion interpolation) and basically adjusting Contrast, Darkness, Sharpness and a few other settings to your preference...you'll forget the big bruisers ever existed (unless you wander into a Chuck E Cheese. I proudly owned a 65 inch 1080i Hitachi set that I dialed in with the help of all the great contributors on this epic thread. But I gave up the ghost many years ago. And I never looked back or regretted the decision. I absolutely love my Sony and LG UHD/HDR panels. Even more than I loved my Hitachi HDTV and Sony 34" XBR970 tank (that was awesome in its day). R.I.P for RPHDTV IMO. And thank you with loving fondness for all of the terrific conversation and support from the old regulars on this splendid thread.

Perhaps you're thinking of the soap opera effect. Screen-door is when you have a screen that is too big and not dense enough. Either way, the density and contrast of modern flatpanels, projectors, and rear projectors is so good that it really puts the CRT rear projectors to shame. The impending coolant leaks don't help those odds much either. CRT projection (even HD) is falling fast & hard, and it is indeed almost time to dump those machines. The question becomes one of whether to dump while it's working or after it breaks. The former greatly increases one's odds of being able to give it away or sell to someone, while the latter is more affordable in the short run (at the expense of a long, tedious, unproductive, and highly unprofitable disposal operation).

Hi there!!
I still have and use on a daily basis two 65813 Mits. I hope they last forever! They work and look fantastic although I know it is time for a cleaning. Anyone still around who can help? I live in Tampa.

yep, i had a 610 Elite and thought it was the best thing since my Sony 45". Had Mr. Bob calibrate and it was spectacular. However, it does not come anywhere close to my OLED E6 or C7

Talking Best of luck

It's kind of funny that a thread about not dumping CRT rear projection is now all about figuring out how to dump CRT rear projection. Best luck, folks!

I'd say, when the thread is abandoned by the OP...the legendary RPCRT guru, Mr Bob...he and most CRT folks have moved on to greener HD pastures. I, truly enjoyed this robust, creative & highly intelligent thread during its heydays. And I made many really great, forum based friendships during the rich commentary with fellow CRT enthusiasts. So I sign off on this thread with fond memories and a wonderfully nostalgic view of the spellbinding HDRPCRT tech...and its avid fandom.

Sony KP51WS520

Still loving my Sony KP51WS520. Doesn't lose anything to the sets I've tried as replacements.

I have reached the point where I am considering retiring my Pioneer Elite PRO 720HD.

It’s been calibrated by Eliab multiple times back in the day, and Mr Bob more recently (but still back in the day). Mr Bob rebuilt the power supply and Pioneer performed some recall work on it at one point.

It’s been a fabulous display but it’s overdue for some TLC so I think I’ll probably call it. It outlived my 5010 by years!

Main question.. are there any parts I should scavenge before I do so? I’m not sure how many people are still using these.

I won’t replace it lightly. I’m thinking maybe 77” OLED.

Pioneer ELITE PRO-720HD | Pioneer PDP-5010FD | Sony XBR-55X850B | LG OLED55E6P
OPPO BDP-103 | OPPO UDP-203

it's been five years since Mr. Bob helped me with my convergence issue back on page 423 post 28199658

Well my WS-73903 lost most of the red's last night. If Robert is still around or someone else can point me in the right direction I would appreciate it. I'd love to keep this old friend in the family a little longer, but I guess 20 years of use is pretty good.

Ok well I guess there's no need for my Pioneer parts. I'm heading down the path of junking it.

PM if anyone needs a power supply or whatever.

My Hitachi 65" Directors Series, the last and greatest of what Hitachi put out, is still rockin' after many years, I bought new in 2003 I believe .. it's 1080i but still pretty magnificent ..

DVI in's take some adapting these days, but hey, it is what it is ..
