[TenTec] Just replaced the backlight on my T-T Delta II

Carl,  I did not have any problems with the decimals or any other feature of the screen.

Joe, K8MP,  TNX for the comment - 

I wonder just how many hours these back lights last?  

73 all,

Hi Kris. The last time I replaced the backlight in a Delta II the rig wound up with an extra dot in the display. Ten Tec said it was caused by stray capacitance. I am just curious if you had the same issue?

 Just a quick note, For what it is worth

I had bought this replacement from England a few years ago and only now got to it - sorry I do not have the name of the company.  The backlight strip came with wires and a plug.

The replacement is delicate, but not a struggle:

Remove top and bottom covers.  

Loosen the top two screws on the side of the front panel, 

Gently tilt the front panel forward;

Unplug three plugs that are on the screen - there are two plugs on the right side, and one plug (serving the back light) on the left of the screen. (Make note of which is which - but it is really straight forward) 

Unscrew the screen - four screws.

lift off the screen by gently pressing from the front - might be a snug fit.

The backlight is plastic and slips between the glass screen and the intelboard and is fed by two wires that wrap around the board from the two prongs frowm which one of the plugs was pulled.

snip the two wires (really are like thick traces of flat wire) as close to the backlight strip as possible.
Gently fold back the two traces so that they are out of the way of the backlight strip as you slide it out.

I used needle-nosed pliers to pull the backlight strip out.

The replacement back light had two wires and a plug long enough the replace the wires in the harness and not use the plug and folded back wires on the board.  I chose to snip them off leaving just enough wire to solder to the folded back traces.  I used tape to hold the traces and wires to the board.

In retrospect, the alternative, use the plug and all, is probably the better idea in retrospect, but the plug needs to be whittled a bit to fit. That would save snipping the wires, pealing the insulation and soldering.    

It is an easy repair and it is so nice to see the screen without having to shine a bright light on it!
