  • Sharp LJ512U27

The Sharp LJ512U27 have moved through our doors just as much as the Sharp LJ512U25. If the glass part of the display is in tacked then we are 100% able to repair this Sharp LJ512U27. Availability on the LJ512U27 - hard to find.

  • Sharp LJ512U32

The Sharp LJ512U32 is a display that was also used in many different machines and we have repaired many of these LJ512U32. Availability on the LJ512U32 - Hard to find.  If you do find some displays make sure you ask the company you are purchasing from if they have completely refurbished and checked the display for burn-in and possible electrode damage.  Also make sure there is a warranty on your purchase.

  • Sharp LJ640U27

This is a very popular display and is still used in many different pieces of equipment. The LJ640U27 has been repaired and retrofitted at Capetronics Inc on many occasions. You can still find some used ones around. Not many LJ640U27's out there. If you do find some LJ640U27 displays make sure you ask the company you are purchasing from if they have completely refurbished and checked the display for burn-in and possible electrode damage.  Also make sure there is a warranty on your purchase.

  • Sharp LJ640U31

The LJ640U31 is a display that uses 5 VDC and 24 VDC as supply voltage.  These LJ640U31 displays are really robust but because of their age we have seen many with moderate to extreme burn-in images where the ZnS:Mn thin film has been damaged.

  • Sharp LJ640U32

In our experience this is the most repaired display to come through our lab. The LJ640U32 is a 640 line by 400 line resolution. The availability on these LJ640U32 displays is "hard to find" especially in good working condition. We are extremely competent when it comes to the Sharp LJ640U32 displays. We used special test equipment and X-rays to repair and test these displays. Capetronics does have a brand new factory warranty replacement display for the LJ640U34 that is also EL technology.  Part number C640U32

  • Sharp LJ640U34

Still an obsolete LJ640U34 display but a newer EL display made by Sharp. Sharp EL displays were the first commercial EL displays to come onto the market back in 1983. We have repaired many LJ640U34 displays and welcome any that you might have that need repair. If you do find USED LJ640U34 displays make sure that the seller has refurbished them completely and have tested the LJ640U34 for burn-in. There is nothing like having Chinese writing as a burn-in image and we have received many of those. Capetronics does have a brand new factory warranty replacement display for the LJ640U34 that is also EL technology.  Part number C640U34

  • Sharp LJ640U35

This LJ640U35 display is a display that has been used in quiet a few medical products back in its day. Also a very robust display and if the display controller has a screen saver function this LJ640U35 should still be in operation in most cases. Of course there are heat and time sensitive components that should be replaced. Availability on the LJ640U35 is of course "hard to find"

  • Sharp LJ64ZU49 Sharp LJ64ZU51 and Sharp LJ64ZU52

We have repaired and refurbished many LJ64ZU49, LJ64ZU51 and LJ64ZU52 displays over the years. These displays are more complex than the LJ640U32, LJ640U34, LJ640U35 and LJ640U27 displays. These displays have something called gray scale option. The availability on these obsolete displays is slim pickings. Capetronics is working on a NEW EL option and that should be out soon.



Capetronics Inc has a complete kit that will convert EL8358MS to a newer display and we have a conversion kit that will convert obsolete Sharp LJ panels like the LJ640U31 LJ640U32, LJ640U34, LJ640U35, LJ640U327 and the LJ640U27 to a currently available Capetronics C640U32,C640U31, C640U34, C640U27 EL Panels.
