i'm not sure if this has been addressed, but i seem to be having issues with my optical out output. i'm trying to hook up my computer to this tv via HDMI cable. i've been able to get video and audio to the tv...but i'd like to send the audio from the tv to my reciever. everything is set up correctly on my reciever, the optical cable was running from my DVD player without any problems. are there any settings i need to deal with on my tv to get the optical audio output to work? i'm also not seeing any light coming out of optical out of the tv. thanks for the help guys.

I think I read that the optical out on the TV only works for OTA (over the air) signals, it's not a pass through for HDMI or RCA inputs.

Correct. F59 optical/TOSLINK out's sole purpose/function is for digital audio from OTA transmissions - allows you to feed OTA digital audio signals to your HT receiver. Only way to get OTA 5.1 from F59 to your HT system.

Update as of 9/2/09: absolutely NO response from anyone at Hitachi (a version of the same letter was also sent to "customer service.").
I, for one, will never purchase another Hitachi product, much as I loved my RPCRT.

24 June 2009

Hank Bartoli, President
Hitachi Home Electronics (America), Inc.

900 Hitachi Way
Chula Vista, CA 91914-3556

Dear Mr. Bartoli:
I have an unfortunate problem.
I have a 57F59A, purchased 10/24/06 from Circuit City (now defunct). I bought an extended warranty at the same time from RepairTech (also defunct).
I recently had to replace the blue gun, which is when I found out my extended warranty was worthless. So I ordered the part (UX26746) from partstore.com on 2/10/09 and received it on 2/24. I installed it shortly after that.
I recently noticed a growing “blob” towards the lower left of the screen, especially when we started watching an old black and white TV series, during which that section of the screen was yellow. I took the set apart and noticed a black streak INSIDE the new blue gun (upper right corner in photo, below).
I called partstore.com, who referred me to Hitachi customer service. I have spoken to several people there, as recently as today (case number 576586), and have been advised that the warranty on parts is 30 days. I find that especially odd, since the warranty on the crt with the set is 2 years.
This is obviously a defect in manufacture. I am amazed that no one (besides me) seems to care that my once fabulous calibrated picture is now unwatchable.
I do not think I am being unreasonable in asking for a replacement for the defective blue gun.
I have been extremely happy with my set until now, and have been an active supporter of it in several online videophile forums, especially two of the Hitachi forums on AVS, and a third called “Don't dump your CRT RPTV!” I would really hate to have to end our relationship because of this issue.
Please authorize a replacement for the defective blue gun.
Thank you for your help in this matter.
Sincerely,

Michael

The number 3 input (component) on my 57F59 has stopped working.

All the other inputs are fine and right now I am using an external component switch for my Dish Network HD receiver and my HD-DVD player, but it would be much more convenient if both my component inputs worked.

Any ideas what has failed and how difficult it is to fix?
post #4628 of 4690
Does it switch and then not show anything, or just not switch at all? If it is not showing anything, is it showing the graphic IDing your input?

The Y connector is the mainline wire that MUST not come undone of the 3, or your pic will disappear. Check it out by replacing it with a known good patchcable.

If all else fails and your set is switching OK, then the Y's internal jack probably has become unsoldered where it mounts to the Terminal board internally, and a quick resoldering of it could cure your problem.

post #4629 of 4690
Guess I should check back if I ask a question, eh.

It switches but no picture, just sound and a few wavy lines occasionally.

Is it the Y connector from the back of the set to the board that I should check?

Maybe this afternoon before the NASCAR race I'll pull the front cover off and trace out the wire.

Looks like it is a bracket setup soldered to the board, I'll have to pull the whole assembly out to get to it, probably not worth the trouble.

I'm looking at getting a Sony HT-SS370 with 3 HDMI switchable inputs to replace my old RCA surround sound anyway.

post #4633 of 4690
Simplest possibility -

Make sure your component plugs are all 3 in, if you use component. If the Pb is out, that may be your problem. If you disco everything but the Y (the green one), do you get b/w like you should?

Hi all,

Been enjoying the set for over a year but I've run into a snag. I have a blu ray player (Panasonic DMP BD60) and I get a big black box that appears in the middle of the screen whenever I hit a function key (rewind, etc.). The movie continues to play, but the box won't go away until I hit a button on the TV remote, like "exit" or volume. Is there anyone that knows of this? Any help would be greatly appreciated.

Ok heres the story. A few months ago, I bought a 51f59 from Craiglist for song and we put it in our basement family room. It was our first large TV and our first TV capable of displaying HD signals. We've been extremely happy with it.

Fast forward to last week. We've gotten so spoiled watching the big TV downstairs that we wanted to replace the trusty old 27" TV in our upstairs living room. So a quick check of craigslist found a 57f59 also for a song. When we went to pick it up, the seller reported that it would occasionally shut off for no reason. He said you just had to turn it back on and it was fine. Ok, the price is right so no problem.

Well its a problem. I noticed when we bought it that he had it hooked up to regular old coax cable. I hooked it up to our Dish Network box via HDMI cable and found that it shuts down often. Very often.

Since my wife is a scientist type, we've been doing some experimenting and have come up with some data that may be useful for diagnosing the problem.

Putting the TV on an HD channel would typically make the shutdowns start within half an hour or so. And once they start, they tend to happen every few minutes or so. Which would suggest heat. But the other morning my wife was using her laptop on the couch so she turned on the TV and put on one of the Sirius radio channels that Dish Network offers for some background music. By mid morning, the TV hadn't shut off once so we left it on the rest of the day to see what would happen. By dinner time it still had not shut off once. She put on an HD channel and it shut off within a minute or so. Turned it back on and put the radio channel back on and it stayed on.

After finding this forum, I found the service menu HDMI fix that is listed in a couple of threads. I put in the fix and put on one of the home improvement HD channels and watched an entire show with no shut downs. Then I put on the CBS HD channel to watch CSI. It shut off within a few minutes. Put the home improvement HD channel back on and no shut down. Switched back to CSI, and it shut off within the 1st minute.

I disconnected the HDMI cable and tried using the RGB connectors but it didn't seem to make any difference, still had it shut off if I put on certain HD channels.

So based on all that, what might be the trouble? I'm guessing its a hardware problem but what hardware would be most likely to produce the symptoms I've described? Any and all suggestions appreciated.
post #4640 of 4690
Find a passage with lots of white in it, so it really presses the power supply to the mat. Or turn the contrast up full for the test, severely overmodulating the signal.

If it shuts off then, you know you have power regulation problems. Something in there may be drawing too much energy, or the regulation circuit may have something wrong with it.

I personally would take the convergence ICs off line and see if the set still works, and if it does not shut down automatically - some brands do and some don't, with that circuit disco'd - I would see if the set stays on with that circuit off line. If so you'll see a really whacked out convergence, but your set would stay on.

If so I would change those ICs out as a matter of course. Not expensive to do, if needed, and many times that's all that's needed. If something that simple proves to keep your set running, you've made out like a bandit.

For what you got it for, you can probably afford to call in a service tech if necessary. They are still needed now and then, the internet is not infallible in replacing them...

I know. I am one of those service techs who are sometimes ultimately needed.

post #4641 of 4690
Thanks for the suggestions Mr Bob. I did a little experimenting this afternoon. I pushed the contrast all the way up but that didn't really give me much of a white screen. So I poked around for some content that had a lot of white in the picture. While not scientific by any means, my casual testing seemed to reveal that the amount of white content had absolutely no effect on the shut offs.

And now that I think about it, my previous observations would seem to confirm that. Namely that the other night I observed it would stay on for quite a while if I put on HGTV but turning on CSI would make it shut off within 60 seconds. I don't know if you've ever seen CSI but most of the show is shot in the dark. A point that really annoys my scientist wife who constantly reminds me that in the real world, labs have bright lights in them as opposed to CSI where the labs always seem to lit by a single candle.

So if we go on the assumption that white content is not causing the shut downs, is there anything else that might be likely? I hear what you're saying about having to get a tech out. I'm not opposed to doing that, but before I did just figured I'd ask the experts here on the outside chance that there might be a cheap and/or easy to swap out part which might have a failure mode that would cause this sort of behavior.

I have a 57F59A. It stopped working several months ago (can't turn on). I took it to a repair shop. After several weeks, the tech there finally repaired it. He told me he replaced the power supply ceramic resistor, rect. bridge and traces. Now i can turn on the TV. But the picture is so dark. I have to turn the contrast to more than 80 and the brightness to 100 in order to see the faces in the video. Can you guess what's wrong? I am so disappointed. I really like this TV. I spent money to have it repaired but have to get rid of it. So sad. Can Mr. Bob or someone here kindly point out to me what might be the cause of it? Thanks.

i would start by contacting the repair tech that fixed it and explain it's not fixed correctly. he had to have tested it before returning it or did you check it when he brought it back?? sounds like something is still not correct and it should have ben corrected or you should have ben notified of this before receiving it back and paying. the tech would have to know that something is not correct if you have to max out the contrast and brightness in order to see the picture. good luck
post #4645 of 4690
Thank you for your response. I am probably busted on this one. The tech claimed that he fixed the "power" issue and didn't touch anything else. He also said it must be this since its a old projection tv. I hoped it could be adjusted when i brought it home. Is there anything can be adjusted using the menu to make it look better without physically change things in this TV?
post #4646 of 4690
It is not an "old TV". These CRT projection sets are ageless, and there's no need to replace it. This is not one of today's "throwaway" sets, that retailers are hoping you will replace in 5 years or so. They don't build them like this anymore. It's only part way thru its service life.

Sounds like the Screen controls need to be realigned to re-achieve the same response as from before, which was obviously correct. Contact me if you want my help on this, over the phone.

He should know that changing parts in the power supply could change energy levels elsewhere in the set. It's also questionable now as to whether the parts he changed were exactly as were in the set originally. Changing their values from original factory values, esp. on resistors, could cause this.

post #4647 of 4690
Thank you very much for your reply, Mr. Bob.
I gave it away today.
post #4648 of 4690
Then you let yourself get torpedoed by your service tech, and you just sank. Multi thousand dollar display down the drain. All your investment - including what you paid the tech, added to the thousands you originally paid for the set - gone.

The first rule of repair when you are a repair service tech is to not give the unit back to the customer in worse shape than when he first brought it to you unless there's no way around that. If it was too far gone in the first place, that's one thing - I may be wrong, but I am assuming yours was not, if the only problem was that it was dark afterwards.

The suggestions I made would have cost a fraction of what you'll pay to replace it.

Don't allow people to try to convince you that these sets are doomed to fail after a certain number of years. Not these. Properly treated, they just keep on going, and going, and going...

Hey, guys. I recently got an antenna to get basic over-the-air channels. I get about 10, all standard definition because my set does not have the built in hd-tuner.

It's a Hitachi 57" and I know there are two: one with and one without the hd-tuner I think. Well mine is the one without, and I was interested in recommendations for external hd tuner boxes. I'm really just wanting to get one so I can watch nfl playoffs ota in hd.

Thanks guys and sorry if I posted in the wrong model thread.

All of the xxF59s are missing a true HD tuner.

I cannot answer your question directly, but hopefully it is OK to throw in my 2 cents.
I am personally building a HTPC.
Pick up a used dual tuner HDHomerun, I got one for $30.
Bingo!
