A few things to look at
Be sure you didnt crack the PCB at FBT.
Check that no harmonica connectors are crooked.
See if fillament is dimming with pix.
Check the G-2 & focus wires are not pulling out of FBT.
Odds are you stirred up a bad PC con moving things around.
Look especially under FBT & the CRT socket. You can find the
blink codes on the internet but IIRC they only come if the
set goes into shut down mode. Makes no sense !
good luck & keep us posted
