As removed from a NAD CD Player Model: 5255
This NAD model was released to the market in the early 1980's
The lovely Toshiba laser head had failed and I have discovered they are EXTREMELY difficult to find replacements for, so the complete machine has been parted out.
Over time, VF displays have a habit of becoming dim and hard to read. If your 5255 is having this problem, this PCB will solve that issue.
This is the complete (fully functioning) front panel VF Display board and the push buttons controls (NO KNOBS)
NAD CD Player 5255
PCB Identification: TK-T134 22192562
Front Panel VF (vacuum fluorescent) Display PCB which includes all the front panel control switches
Only one knob is supplied, the sliding switch control for TRACK-INDEX display
COSMETIC CONDITION:
There is no physical damage to any of these components
All items are clean
Display front glass is clean, unscratched and without damage
The remainder of the buttons and the front panel darkened glass cover are available in a separate advertisement
TESTING:
Fully functioning prior to removal from the 5255
Display is green/blue, bright and very easy to read in all light conditions
Due to the design of the 5255, replacement of your existing display PCB is not difficult - no de-soldering as extensive use of "push/lock" connectors is used by NAD in this equipment.
This display board is secured in place by 2x screws (supplied) and a number of click-lock posts, much as with the buttons. It must be ensured that none of those posts are damaged otherwise the board will not sit properly and the buttons will not work correctly.
Hint: just make sure the power supply rails from the PSU are correct otherwise you may end up changing the display board unnecessarily and the issue could be with the power supplied to the board, not the board itself.
Finding schematics for the 5255 is not an easy task but if you look at my advertisement for the PSU, I have given some indications of voltages that you should see at that unit - it might help.
Since removal, this PCB is now sealed in plastic.
