NO PICTURE...BUT SOUND

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!!!! Thanks, Steve

My Zenith R56W28 had gotten progressively darker to the point where you could barely watch it.I opened the top (projection) compartment on mine and blew it out with an air pump.Helped a little.Then I took the screws out of the left half of the back on the lower compartment where the electronics and power supplies are located.Stuck my air pump hose in and blew out all the dirt and dust.Checked the picture and it was as good as new!I love these TV's!First problem I've had with it in 15 years!Practically bullet proof!

Your HV circuit is defective. Most likely horizontal output transistor is shorted and you may need to replace the flyback. You need to call an expert.

The picture does not seem as bright as it was

This rear projection from the model number appears to be a RCA AND not the zenith listed in your question.

If RCA the lens for the tubes may be dusty or dirty--should be cleaned once a year.

Process is simple: unplug set and remove rear cover.

Locate the three large black lens at top of chassis and either with a lens cloth or a paper towel with glass cleaner sprayed on the towel clean them.

If they are dirty/dusty they will make picture look darker and duller than it once was---they are the light source for your picture.

Toshiba 27A45 picture and colors began to get darker and darker until whole screen is black. Sound still good. After a minute or two the picture returns fast.

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

No Picture

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.

There is a shadow of red all across the top half of the tv. Perhaps something with color convergence?
