Suitable LCD Display Replacement or Repair for WSA1 ??

Hi folks, the display on my WSA1 is slowly going funky. Is anyone aware of a replacement available? Maybe one from a K series? Or even someone that can repair them? I have attached a picture of what mine is doing. Thanks.

Hi ATS,

I've put some queries out for you. At least it is still mostly readable for the time being , that must be very frustrating!

Hope to get back to you soon.

Mike

Thank you so much Mike it's greatly appreciated. It is pretty frustrating trying to learn my way around the WSA1 with the top half of the screen cut off smiling

Hi there! new WSA1 user and will be looking for more info as I begin to learn this wonderful classic and unique synth.

Was there an option for replacement screen (like Cool Blue alternative) - looks very large and maybe somewhat difficult to find a replacement for ... like for like.

Hi All,

I've read some info on the net that people have had success in using old photocopier screens in them. Not getting very far with research as of yet I was hoping that the screen might be common with KN2000 but it doesn't seem so.

I've upgraded you so you can access the additional downloads.

Cheers,
Mike

Re: Suitable LCD Display Replacement or Repair for WSA1 ??

Thanks a lot Mike, much appreciated - would be very interested if there were ANY alternative, as I say, this looks to be quite unique and therefore maybe only a few options on this (worldwide). Did Technics UK ever come back on this topic with anyone else on this forum? - doubt they still have any stock of course but typically the big OEMs find 'alternative' replacements for aftermarket in support of their customer base, worth an ask.

Best Richard.

ps. as new WSA1 owner I'll be trawling this site for more info, patches, programming tips etc., so looking forward to that - good to see so many other dedicated users still !

Hi Richard,

The part number for the WSA1 screen is QSLG017AA and if you Google that code you'll find a few parts companies that claim to be able to source it still. As you're in UK you could also try W D Greenhill who might be able to source it.

If you Google WSA1 display or search for it on Ebay you'll see a video from someone who replaced his screen with a photocopier screen part number HLM8218 which appears to be equivalent to a Sharp Sharp LM32P18. However, that would take quite a bit of research to get working! I'll attach pinouts for the Sharp to this post but I have no idea whether they will help. I've tried to find pinouts for the original Panasonic item but can't find then you would have to look carefully inside the WSA1 and trace back the circuit diagram to see if any of this is useful, it might be a red herring! Even the Youtube video doesn't actually show the replacement screen working.

I'll be making more enquiries as and when I can. There are various websites selling replacement screens for devices if the correct information can be gathered.

For info, the KN2000 screen is a slightly different model number (QSLG011AA), both have 320x240 dots

Regards,
Mike

Re: Suitable LCD Display Replacement or Repair for WSA1 ??

Hi Mike - apologies for late reply following your helpful response.
Did have a brief Google however like yourself no specific success, though as you mention if we can find the actual Panasonic connection detail then no doubt a modern equivalent can be sourced from one of the guessing larger mass electronic/LCD display distributing Co.s worldwide.

I've had a contact previously at WD Greenhill when I was after some obscure Kawai parts so can try in the hope there, though nothing in the Technics area of their site (maybe they can point me in the direction of an aftermarket Technics Co. who supply older keyboards etc.).

Due to receive next week a classic KN1400 which happens to have what appears to be same LCD footprint and now reading up a bit, was a 'budget' end keyboard that carried over these 'pro' large screen displays .... who knows maybe they are in some way interchangeable (saw KN2000 Pt. No. was different though does look same unit?).

More trawling this weekend Mike. In the meantime still enjoying my unique purchase in the WSA1 - the UI is genius compared to even my more modern synths from the Big 3.
Why don't other OEM's use this concept? Yet to even read in detail the accompanying manuals the guy sent!!,
As so easy to find way round.
Was intersects in the (only it appears) expansion "Dance' board which is no doubt nigh impossible to buy separately, as the very few made as I understand it, are bound to be fitted in the WSA's of current owners. Though also reads a not particularly great in content ....

Thanks again Mike and please let me know if you get any joy further,
BR Richard

Hi Mike and all! Just wondered if anyone had any updates on this regarding replacement for my WSA1 LCD - must be an equivalent that I could get from an outlet I'm certain, or even pulled from another ailing board/piece of hardware.... look forward to any support on this one, cheers Richard.
ps. also now managed to get the rack version too! sweet smiling

Hello,

Still no news about a possible LCD replacement for you WSA ?

Have someone looked at or tried the HLM8619 or 8620 for example as an alternative (same PIN numbers 14) ?

Alternative display specifications sheet and WSA1 pinouts details from the service manual are attached.

Hi Kiolbo - hope you are fine. Great post smiling , thanks for a useful post from my previous (quite old now!) queries.

Only 'issue' I see is that the Pin7 states "NC: Not Connected" on the new LCD, whereas the Technics Service schematic shows "-22v" as per Pin2. I'm not a power electronics expert (by any stretch of the imagine ...), however I may be that this can be routed in parallel with Pin2 (?, not sure on current draw, etc.).
Anyway, it does look to be a very close match, so good work on that search.

Any power electronics wizards on this forum can comment please?

Look forward to your replies!!, as I'd love to update the OEM LCD ASAP smiling

The company responded: they can’t get them. But they sent this link suggesting they are available from Panasonic-

Just sent a query to the panasonic.encompass site, after Kyle at UED replied that Encompass had replied that Panasonic in the US no longer has the part. Have written directly to Encompass asking for a contact inside Techics/Matsushita/Panasonic itself. Will report on their reply.

Mentioned that we need specs for the original part and suggestions for possible substitutes for replacement.

Watching your progress with avid interest.

If you get anywhere we'll be very interested as to whether they could supply screens for other models too but I'm guessing that the cost might be greater than buying a replacement used keyboard for most models.

What appears to be Panasonic’s final word via their official N America supply chain:

Thank you for your inquiry. Please follow the link below for pricing, availability, order details and to place an order.


We appreciate your business!

Status Completed

So for those with current screen issues this appears to be an official fix ie for getting a new replacement part. Time to query those brave ones who forged ahead and know how to make the switch without breaking things.

For those who might want to get a spare now for the future, some hold that the shelf life is not great on these. Not sure I can agree since the screens in my WSA1 and WSA1R look crisp and clear though they would appear to be nearly 25 yrs old.

Re: Suitable LCD Display Replacement or Repair for WSA1 ??

They always seem to be helpful and able to source most parts if you're persistent. But rarely affordable to most people.

Not so with software, they are singularly unhelpful unfortunately.

One thing I'm looking at is 3D printed keys for most Technics models. There are possibilities of replacing with inverted keys, coloured keys and so on. I'm considering a re-spray of one of my WSA1s and to have black keys instead of white, with red sharps and flats. I like the idea of it but there are always higher priorities than keyboard aesthetics.

WSA1 is one of the few models with weighted keys. They feel great in my opinion. Some of them appear to be weighted with lead shot, encapsulated in resin. Should be safe, but please don't eat your keys.

And with that comment, you can tell that I'm extremely tired. See you soon.

PS but talk to Marc about keyboard aesthetics!

(guess where the inspiration for my coloured keys came from)
