Hitachi 51/57/65F59A CRT RPTV Tweaks Thread - Page 154

Good list.

Don't forget about the optical focusing, I would recommend using the Cantilever Technique. You can find info about that in my video on the subject at my channel on youtube (see my sig).

The focus block pots do the focusing on the CRT faces, the Cantilever Technique focusing is for the projection of that image and involves the lenses themselves.

I am available for phone consultation if you want a calibrator's take on how to do any of those steps you mentioned.

i want to forward my audio coming in from HDMI input on my 51f59a to soundbar(samsung HW-E450C/ZA-RB)

but it seems that i cannot do it (per userguide). the optical out works only for the digital tuner on TV... i also read somewhere that a digital coaxial to optical converter might work.. is that true? if not what other options am i looking at so i can control soundbar volume using TV remote..

the soundbar has HDMI and optical inputs...

Nothing comes FROM an input, and I don't believe Hit provides an output at the TV for the digital audio except as you say, for the built-in tuner. Which is not what you need for playing bluray or a STB. You need to parallel your signal material that's getting TO your TV's input and make it also appear somewhere else - in this case your soundbar.

Hopefully your AVR has HDMI inputs and outputs, which would allow your HDMI signal from whatever source you are running at that time to get interpreted and amplified by your AVR, and then that volume controlled digital audio content sent out again as well. In which case the HDMI OP of the AVR would go straight to the soundbar and be controllable by the AVR's volume control.

If not you may have to get either splitting or switching of your HDMI signal, so that one can go to the soundbar while the other goes to the amp. In which case each would be independently controlled, volumewise. Not the best scenario...

Or use optical from your signal source and go to the soundbar, while the HDMI from the source goes to your amp. In which case you may need switching if you have more than one signal source - like a bluray and a STB.

It's a rather complicated equation, I grant you!

do you know where i can get a mirror for my hitachi 51f710a tried to get to the highreflectivemirror web site but link must have been broken.. thanks

Try Hitachi directly. They also have a rebuilder who might have spare mirrors. Can't remember its name right now, but somebody here will probably know. If you want me to get you one contact me directly, I have access to Hitachi as a repair servicer. And other brands.

Hello, new to avs.

Purchased a 65F59A today without the remote.

Got it home and it worked fine for 30min. Then went red for a split second and shut off.
When turned back on, the picture had a red tint to it.
Left it off for a while and when turned on again everything was fine.
Also, the sound quits working sometimes when it happens... Strange

Anyhow, after reading for a few hours I am no closer to finding a solution especially
since I don't have the remote for it.

I'd ask if this would be an easy fix for me but I think the better course of action
is to ask:

Can someone please direct me to someone in my area that is a guru on these sets...

I need it fixed by an expert...

You can shoot me an email @ Orbitter0@gmail.com

Oh, btw... I live in Bellingham, WA which is about 70miles north of Seattle

hi Bob, thanks for your reply.. it would be great if you know of someone that may have A MIRROR FOR MY HITACHI 51F710A as it has been discontinued through sears.. the part number is KSO7996...or what it would cost through you.. I found one for a hitachi 50 inch but the part number is not the same.. thanks lonnie

This is something my business does on a paid basis, so contact me directly and I'll see what I can do. Best to not conduct $ related transactions on this site, they like to keep it an all volunteer thingamagig here -

I have seen this type of behavior on the Pioneer Elite and non-Elite power supply boards of the 510/610/710 model year. I have been successfully repairing them for years and restoring totally reliable operation again permanently, via comprehensive resoldering of virtually the entire board. Not something you want to try unless you are professionally experienced at it already. There's far too much that can go wrong, which could damage the rest of your set.

Contact me directly and we can talk about it.

I am new to the AVS site and would like to thank you all for the help and sharing of information for the rest of us. Thanks again.

Welcome!

This is just one of 5 threads about Hitachi CRT sets you might want to check out.

the issue i am having is on a 57F59A - i have a ps3 connected via componant cables and a standard coax cable line hooked up. regardless of the input, at random times the screen just flicks to black. the red power button stays on, but i will hear a quick static sound...almost a popping noise....and the screen will turn black. i will have to turn the tv off and back on, but its getting worse to the point where i cant watch tv anymore.

only fix i found was to unplug the tv for about 30 mins to reset the board or something. that didnt work.

i also saw some info that it could be the Capacitors and i may need to solder new ones to the board. i got the tv in 2006

Sounds like there's a cold solder joint somewhere in your set. Could be on the power supply board which feeds a certain section, or in that section. If it goes black, you may need to trace out the signal path with an oscilloscope. Or if you are willing to take on the responsibility of working with live circuits, you might want to try manipulating the board by tapping on it with a non-conductive item like a pencil with an eraser on it, or giving it little mechanical shocks with a screwdriver handle with the shank taped up and insulated.

But this is potentially a very dangerous thing to do, so don't even approach this situation unless you know electronics and are experienced in it. Potentially deadly voltages are in there, so don't just rush in - don't even go in unless you have the training and the carefulness it takes to keep yourself safe.

Hey guys Im back after a long break. I retired and moved around. Almost retired my Hitachi 51f59a but put it in storage instead. That was more than a year ago. Im having it shipped to my new place. Everyone thought I was nuts to stay with it but the pic is so great and I have put so much work and time into it I couldnt do it. Plus I really believe the pic is better than whats out there. So if any of you remember me I have done darn near every tweak there is but a few. I moved the guns closer to the mirror, schemper&^%$% whatever, black out, shimmed the outside guns, put up a shield in front of the guns and a whole lot of adjustment tweaks. Some done with phone consults with Mr. Bob, which saved me in a grayscale nightmare once.

I turned it on and it looked good. Hope the shipping goes well. I will need to remember a lot of the adjustment tweaks but Im sure I will get there. Ordering a new remote this week too. The old one grew legs and ran off.

Welcome back

Retiring myself in a year and deciding what to do with my 65F59a. Works great looks great but no one in my family wants the 300 pound+ breast. So I guess storage it goes until I figure out where I end up.
