Replacing R95 on the small display board without lifting traces

Steps

• Snip the old R95 off right at its body, leaving its leads in the board.
• Solder the new 33k 1/2 W resistor to the old leads; pulling the old leads out tears the traces easily.
• If the display is still garbled, check continuity from the top of R95 to the top of R94, and from the bottom of R95 to the top lead of Q2.
• Repair any broken trace with a jumper wire.
