phish Posted March 4, 2011 Report Share Posted March 4, 2011 I recently got 2nd hand Black MZ-RH1 (North America market model) and found its EL display too dark to read. I have Silver MZ-RH1 (Japanese domestic model), it doesn't have any brightness problem. The ex-owner said it was too dim when he bought. Is there a way to control the brightness of EL display? Or I have to stop by SONY service to replace the EL unit? From the picture, top one is Black MZ-RH1 (USA model) and the bottom is Silver MZ-RH1 (Japanese model).

NickyJay Posted March 4, 2011 Report Share Posted March 4, 2011 I believe the OLED screen on units like the RH1 (and also RH10) shall slowly keep fading until it eventually dies out. It's one of the reasons why, despite the screen looking fantastic, I have never invested money in one. Quote Link to comment Share on other sites More sharing options...
sfbp Posted March 4, 2011 Report Share Posted March 4, 2011 I'm not 100% sure I believe this. The LCD displays on both NH900 and RH910 have a habit of getting dim too. In that case it's a simple matter of following the adjustment of the main power circuits as laid down in the first page of "Electrical Adjustments" in the Service Manual. It occurs to me (I cannot get into Service Mode on my RH1, and in any event the display is not dimmed) that perhaps following the adjustment for the RH1 will actually fix this problem.

sfbp Posted March 8, 2011 Report Share Posted March 8, 2011 When I try to fix it in Service Mode, don't I need the tech gears suggested by service manual? Sure but you don't need (or want) to do ALL the adjustments. In particular, you should NOT do the 911 Reset NVRam under any circumstances. To get the voltage adjustment right you may be able to get away with one regulated power supply and a digital voltmeter. This assumes you know what you are doing and don't mind losing the whole unit if you mess up. Quote Link to comment Share on other sites More sharing options...
nanaman08 Posted July 27, 2014 Report Share Posted July 27, 2014 Hi I think I have done the 911 Reset NVRam By accident and now when I take the battery out the battery light flashes and it starts beeping any advice on what action to take?

sfbp Posted July 28, 2014 Report Share Posted July 28, 2014 Jim Hoggarth's your best bet.... but he's been under the weather lately and you may have to wait a very long time. I could attempt it, but it's rather a pain to send to the other side of the world. Or you can learn. But you'll need some gear, and some knowledge about how to make test disks. Sorry, only bad things can happen if you start messing with it in its present state at random. There is, I believe NO quick fix to undo what you just did.

nanaman08 Posted July 28, 2014 Report Share Posted July 28, 2014 What about if I send it to sony do you think it is something that they can fix? Also were can I buy parts for it? I need a new screen as only the left side works.? Quote Link to comment Share on other sites More sharing options...
punkrockaddict Posted July 28, 2014 Report Share Posted July 28, 2014 Hi Forget about Parts ... Sorry. I already changed some oled for the RH1. These can be changed or disassembled at each side.But that is not easy. I got some spare Displays but i think most of them were half working or just dark. GettIng parts means buying a 2nd RH1 :-/ So considering the Oled there is no fix rather than usIng a spare one and that is hard to get.

nanaman08 Posted July 28, 2014 Report Share Posted July 28, 2014 What about sony will they be able to fix it? Also would you sell me a spare display even if it is dim in display. Quote Link to comment Share on other sites More sharing options...
sfbp Posted July 29, 2014 Report Share Posted July 29, 2014 As he says, these parts are essentially unavailable. However, it's not impossible that the various reported OLED failures (dimness, essentially) are the result of overall power adjustments being needed. I took a peek in the service manual and there's nothing specific about adjustments for the OLED board, just something about replacing the whole board. But with a number of other models (ie NOT the MZ-RH1) whose displays could not be read, I found that problem to go away on the first or second power adjustment on the list - ie the entire machine is running on low voltage.

punkrockaddict Posted July 29, 2014 Report Share Posted July 29, 2014 Putting a 100% dark RH1 Display Board to a working RH1 didn't light it up.It was just äs dark as before.I think it just died cause its age and of much usage.also half dimmed ones acted just like in their original Units. So why should this be a power Problem? It simply points out to a dying Oled. Most dim or dark displays i've ever seen came from really used Units. This might be the Point...

sfbp Posted July 29, 2014 Report Share Posted July 29, 2014 OK fair enough. If you've actually done this, then your logic is irrefutable. I thought I might raise the point, sorry. Quote Link to comment Share on other sites More sharing options...
punkrockaddict Posted July 29, 2014 Report Share Posted July 29, 2014 I did yea.I also took the Oled Board from a half dinmed right side and put another proofed working Board to both Oleds. I hoped the small Board itself was defect but it turned out it wasn't. Sad but true... I think i got 8 or 9 RH1 in total and 1 really looks like brand new but its Oled is 100% dark. Another One with the most usage is 50% dim at the right side. Maybe i should sell some before they wear out :-/ but i can't :-D I just love em too much Quote Link to comment Share on other sites More sharing options...
nanaman08 Posted July 29, 2014 Report Share Posted July 29, 2014 Ok so guys do u think sony will be able to help me I was using it fine even with the right side oled screen not working.it's just wen I went into service mode.And now won't go back to normal working order Quote Link to comment Share on other sites More sharing options...
punkrockaddict Posted July 29, 2014 Report Share Posted July 29, 2014 Iam not sure..maybe one could write down all values off the SM to fit into yours. That would be what i would try. That is of course not the best Solution if at all. I guess Sony would charge you quite a lot.If they are even able and willing to do it. Why not just ask them?

nanaman08 Posted July 29, 2014 Report Share Posted July 29, 2014 Yes well I have sent it of to sony and it's a £70 charge for parts and labour but if they can't get the parts or are unable to fix the issue it's no charge. I am so desperate to get this fixed.I even emaild Jim hogwarth but no reply?? Quote Link to comment Share on other sites More sharing options...

JG98258 Posted August 7, 2014 Report Share Posted August 7, 2014 Is the OLED display necessary? Are there things displayed on it that aren't displayed on the remote at the same time? I've never checked. On my RH1, I always use the remote to start/stop tracks, FF, rewind, etc. to save wear and tear on the control on the RH1, and I turn the OLED screen off to save it. I want this little guy to last. . . Quote Link to comment Share on other sites More sharing options...

punkrockaddict Posted August 8, 2014 Report Share Posted August 8, 2014 It is necessary when Recording in the dark. That is exactly what i use it for. Of couse you can use it a defect or dim Display. It even works when the display is taken off :-D But you don't want to try. Quote Link to comment Share on other sites More sharing options...

wellsm Posted September 15, 2014 Report Share Posted September 15, 2014 Just for everyone's info, I have this problem with the left hand screen and I have contacted the Sony Service Centre in the UK today, unfortunately they told me that they no longer carry parts for these and in fact the last two sent to them for repair have been returned to the customer.

freddyjollo Posted September 16, 2014 Report Share Posted September 16, 2014 I hate this technology that cant be repaired. Which ever clever dick thought up OLED displays, he/she should have an accident? The non backlight type are good enough I think. Quote Link to comment Share on other sites More sharing options...
nathantw666 Posted February 2, 2015 Report Share Posted February 2, 2015 I know this is an old topic, but it's just driving me mad that my OLED on the RH1 is fading to black. I didn't use it anywhere as much as I'm sure some people have used theirs and it's still going dark. Sadly I'm thinking it's the age that's killing the OLED. Once it goes dark, I'm thinking that maybe a newer solid state recorder will be in order instead of buying a new RH1 since the display will be dark after 7 years or a less. FWIW, I sent my unit to Sony last August and they sent it back saying they couldn't fix it. Quote Link to comment Share on other sites More sharing options...

punkrockaddict Posted February 4, 2015 Report Share Posted February 4, 2015 The Oled is organic.. so it is not calibrate- or repairable.It is simply aging and getting dimmed after time. I used to set all my RH1 and of course RH10´s displays to auto off when iam not looking at it. Such a nice display should be used imho. That is the one and only reason iam using my RH1 for taping.

nathantw666 Posted February 19, 2015 Report Share Posted February 19, 2015 dont u have the remote? can it substitute for the display on the main unit? Unfortunately you can't change menu options by remote, at least the one I'm using. I need to use the left hand screen on the rh1. The remote I'm using is the one with 3 lines of info.

nathantw666 Posted February 19, 2015 Report Share Posted February 19, 2015 I always set my displays to auto off because I use the remote for all operations. Unfortunately the display still aged and is about 40% of where it was new. I wish there was some way we could retrofit some LCD or even a color oled display in its place.
