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.

Tv won't turn on

I donot know the model # but if it is 11 years old, it is the classic we have a lot of bad caps. If the fuse is good, this is all you need. Maybe 10 or 15 of them can be found with the cap check. If the fuse is burned, replace the H.O.T., the poweline reg. and that small voltage reg just two inches away. [other side of heat sink] See the NTE cross ref bible for semiconductor replacement. The resistors are usually good. Caution High voltage inside!!!!!!!!!!

16 yr old 25" Zenith..1st colors went yellow/lime now TV is dead

Absolutely not worth repair. You have described a classic symptom of Zenith picture tube failure, and about 99% of the time the main board in the TV is ruined as well. You've gotten good life from the set (manufacturers figure tube life is around 7 years these days), so it's time to replace it.

I do not have a Zenith B25A02Z TV. What I do have is a 1988 Zenith Color TV SE2517P. I called a local tv repairman and discussed the problem over the phone. He can take a look at it if we bring it in (service call to the home cost $100 just to show up). He said it was worth fixing since he thought it was only the sound. We have a great picture. He charges $20 to look at it but we have to leave it. He lives 20 minutes away one way. We think it is worth the trip if we can get it loaded into our minivan. We live in western NY where the weather can get pretty ugly many days. I will post the solution later when I know. FYI

Picture is dark

Does not seem like a bad tube alone. Could also be that the Video output Transistors Supply Filter capacitor having dried out. It is a 100mfd 160V capacitor, which on replacement will improve the brightness of the immage. And yes, you could also try increasing the heater voltage (Filament Voltage)of the Pictuire tube, this will definitely increase brightness, but will reduce the life of the Picture tube. You gotta think - 10 year old TV, should I repair or exchange and get a new one???

Zenith 25" Color TV - Model A25A23W

Your problem is a bad connection on the CRT socket on the CRT driver board, a bad connection in the RGB driver supply from the video jungle IC or maybe even an intermittant Picture tube. the only way to tell would be to tap on the crt board while the sets playing with a non conductive insterment, and see if it changes. Now there is alot of HIGH VOLTAGE at this spot, so if you have no TV repoair experience Please stay safe and call in a pro to assist you. Good Luck Please dont forget to rate this thread.

Zenith 25in. System 3 TV. Intermittent problem with color going all red??

It certainly sounds like a drive problem in the set. It could be a bad connection on the CRT socket, a componet on the CRT driver board, a bad drive transistor, a connection between the CRT driver board and the RGB /video jungle IC, or the RGB/video jungle IC itself. If you know how to solder and or have some sort of solid state repair experience, you should be able to find this problem by simply probing around with a wooden or plastic tool tilll the problem arises. If you have no experience, there is no easy quick fix. You should find a local repair person to assist you with this repair. good luck PS Please dont forget to rate this thread.

Color mostly green

Sounds like tyo me that the picture tube is getting soft on ya!!. Its a common factor that occours with all tvs but mostly with zenith. A service tech might be able for a small fee rejuvinate the picture tube but theres never a warrantee with this type repair. Its not something a user should attemp to do as theres hi voltage inside this set even on the tube socket after its ubplugged for awhile. Seek the advise of a repair pro to see how bad the tube is. Good Luck
