Picture tube cross reference

I have a bad Zenith tv picture tube. Part#A51AGD33X. I have a bad RCA tv w/ good picture tube. Part # A51ACG34X02. BOTH ARE 19" and the RCA tube fits just fine in the Zenith TV. Are the picture tubes compatable??
Thanks in advance for any help,

Colors going bad on my tv?


The picture tubes in Zenith sets (I assume it's a Zenith since you posted this with a Zenith heading, although it's also true for any set this old) were only expected to last around 7 years. Your description makes it sound like you are missing green, or that the green is just way low. This is a common sign of a bad picture tube. There are other possible causes, but tube failure is the most likely. The low replacement cost for small TV sets makes repairing this one uneconomical.

Get rid of the set and treat yourself to a new one.

Assuming the picture tube lights up and you have snow when selecting the tuner function, I would first hook up a working VCR with a good tape and play it while the set is on channel 3 (if that is what your VCR is set to). If no sound or picture is displayed while the tape is playing,it could indicate a defective tuner. If you don't even get snow with no antenna connected (unless your set is designed to go to a blue screen with no signal present) then you could have a problem in the video processing circuits which would explain no picture with the RCA connections as well. This would probably make the set beyone economical repair.

Zenith A32B43W color problem


Classic symptoms! Most of the last TV's made by the old, original Zenith company (Rauland division) had bad picture tubes even when new. This probably had something to do with their going out of business and being taken over by a much better Korean company (LG Electronics AKA Goldstar). Another lovely thing they did before biting the big one was to only sell a complete chassis as a repair part. If your TV is older and has a small white paper tag inside somewhere on the picture tube (usually near the larger brand and type number label) with the code "EIA 1101" on it, discard it. I have NEVER seen one of these work correctly! If the CRT is made by someone else, there may be slight hope. Even if the TV is not very old, if it was really made by Zenith, and not LG, the possibility of repair is slim simply because of the change of ownership. I was sad to see Zenith die such a horrible death. They used to be fairly good, but somehow never made the transition to color TV. After 1954 they were essentially moribund.

What makes you think the picture tube is bad? What exactly are the symptoms you see? The RCA 20 inch picture tube is a good quality long lasting tube and I doubt I have ever seen a bad one.

Your going to need to hook up a cross hatch generator to adjust the internal convergence alighnments. Anytime, a tube is replaced, there is alot of alighnment involved with the convergence, and it cannot be alighned from the customers convergence controls. I suggest first you get a service manual, and follow the alighnment to the letter for the convergence. If you do not have a cross hatch generator, then your going to need a test disc(DVD) that has a cross hatch on it. If you do not have access to those two things(cross hatch generator or the test disc) you will need to call out a tech to do this alighnment to the set. They (service tech) don't tell you when you get an estimate for a picture tube that there is some alighnment involved that reguires special test equipment. Thats why they charge what they do. I wish I had better news for you, but without proper test equipment, this is going to be a tough battle. Good Luck Please do not forget to rate this thread.
