Jim -

I would challenge your claim of the 1st blue TR-7.? I would think that
belongs to Triumph Motors, 3 years before the Drake!? ;-)

More likely it is a broken trace than anything else. The display board is a nasty bugger to unsolder. The LEDs are a standard off the shelf pinout, you could replace them if bad. Not that I am discouraging you from sending DF4NW some money, he is a good guy. I bought the first blue display in the original LED size from him. Since I had already changed the ALC lamp to blue I had the first all blue TR7 in the world, a claim that has not been challenged to this day!

Hi Jim

Managed to repair one of the spare PTO's all fitted back and seems to be? working ok.

Not putting the front back as I am changing the bulbs to blue LED's.

Then to the DR7 will check through again, thanks for the tip on checking the segments, will do that tomorrow.
If those LED's have a problem I will check out DF4NW to see if I can get a replacement.

Hoping it's just a solder joint.

Kind Regards
