Re: TDS3044B repair

I have a TDS3054 I bought new 20 years ago and I never noticed how dim the display had become over the years. I was able to replace the CCFL tubes with new ones and it made a huge difference in readability.

You can replace the CCFL tubes as slide-out FRUs, NEC part #65LHS–3L Or, solder in bare CCFLs. I did the latter with tubes from ccflwarehouse.com, part #CC26153. You will need two tubes. The TDS3xxx "B" version uses the same CCFLs according to the Tek service manual.
