Have a Zenith model #Z56296D8 that recently the picture started to get darker. Now the picture is black, but when I change channels I can hear the channels fine. (3) years ago I replaced the High Voltage Module, is this the culprit again?? The TV is in a heavy smoking environment, does this effect the module?? PLEASE HELP!!!!

Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store. Diagrahm inside set will show you location of transistor
i have had this problem on one of my tv s all i did was remove the back of the tv and re-solder all the joints around the tuner (thats where the arieal goes) they go with time because the joints there get so hot . hope this helps
Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.
