I have a k7000 25" monitor that was dim most of time and was in need of a cap kit. i finally got around to doing a cap kit on this chassis. Now i have the cap kit installed and verified all caps are correctly installed and reflowed all the existing solder joints because i know these k7000 are known for cracked solder joints. I installed the chassis back into the cabinet and attachd the anode cap. Now i have no neck glow and no picture at all. I doulbe checked all caps are correctly installled. What would you check next? If i cannot get this to work where can i send this chassis to have someone fix it for me? Thanks for any response!

Do you hear a quick burst of HV static when you first turn it on ?
Have you checked the B+ voltage ?
(it may be high and going into shutdown)
Even though you checked solder joints..... double check EVERY large resistor again. There are a couple spots that will crack the trace near the joint that will kill the heater voltage, hence no neck glow.

If the tube filament is glowing then the horiz section is running fine.....the filament runs off the flyback.
Did you cut/remove any wires when you did the cap job? 'specially the gnd wire that ties to the neck board and the tube dag.

Yes i cut a gray wire that i assume is a ground, but i did connect it back when i put the chassis back in the cabinet. I just twised the wire strands together but that should be sufficient ? correct?

Make sure this wire is connected and making a GOOD connection:
