Panasonic 29" TV, Model TX-29GF10X



Has a red tinge over the complete picture. No green is showing. Just red and blue.



Measured the KB,KG and KR (assuming these are the cathode voltages) on the CRT board with it connected and disconnected



KB =120VDC KG =195VDC KR =195VDC



Also removed the board from the CRT and did the same test and same voltages apply. Going to swap some of the output transistors but am pretty sure they ok.



Where to look next???



Thanks

Did some more. Swapped the transistor gun outputs (KR and KB) and the colours changed. So the screen that normally is blue when you get no TV signal is now red. Proves that the tube should be sweet. Can see a bit of green in this config, but very low.

So it obviously is a signal issue. This is where it is out of my league.
