Re: Another A5 board repair attemp - help needed

I had already replaced R2012 but forgot to check R2013, which was open!
Both have been replaced with TE RN73C2B10KBTDF from Mouser (10K, 0.1%, 10ppm).
Now the scope boots with TEST4 FAIL2 but after pressing A/B TRIG the horizontal lines is visible and the vertical position control work.
The next step is to find what is causing four dotted lines to appear near the top and bottom of the display.
I have uploaded a photo of the display to the album related to this thread (
Are they related to the error?
Thank you all for the help.
