I have a Mitsubishi WT-46807 wide screen HDTV ready reprocjection TV. Replaced the STK's 2 years ago due to an hourglass effect.
Lost the red gun / crt Filament is on. There is a red hue I would say 5% output. CRT connector red printed circuit board: K voltage is about 140V G2 is 18V
Blue which is okay has similar voltages.
Both blue and green crt's are fine and converged. Red does not have enough intensity for convergence.
During initial failure we had high red content at startup and then a normal picture.
Now there is no red at any time.
One manual I have read identifies a chirping that I have heard which indicated a high load on the 110V circuirt and the power amplifiers.
