Zenith Presentation Capacitor

Thanks for the information about the need to replace the capaitor for our Zenith Presentation TVs at the schools. Are all universal 100uf 50 volt capacitors the same or do I need one specifically for this model of TV? I see they are very cheap but wanted to make sure I order the right ones? Any suggestions as to the best place for ordering them? Thanks again for the help!

Hello again! Sorry, I was not more exact... capacitors are not all alike...too long to go into...100uf 50volt Electrolytic Capacitors are what you need.
I always use the phone to order what I need and when you tell the parts person you need a 100uf 50 volt cap it's already understood that you want Electrolytic capacitors. It' s pretty rare to have to order the other types of capacitors as they are extremely long lived and are not in "high stress" circuits anyway.
Can you please tell me the model # of these sets. I will obtain (if I don't already have it) the service manual and make sure I am telling you 100% correctly what your problem is. Zenith tv's have always been notorius for this problem all through the '80s \ '90s \ early 2000s though. That's why I am telling you it is this same capacitor in all these sets
It makes me happy to help a school too! I am the single Dad of two elementary school age girls.
Is your school system in the USA? Just curious... Hope you have nice day!

    Hello! I couldn't find the schematic online yesterday and may have to visit the Authorized Zenith Service Center here in my city to obtain a copy...I used to work there. Anyway, I will continue my search for the schematic today. If all else fails you can send me a picture of the circuit board and we can get the units working. 90 % of these tv's will have the exact same problem.I will get back in touch with you to update you with my progress.

Where is the lamp ballast on a zenith z56dc1d. Thanks

Douglas, the ballast is what the lamp plugs into, pretty sure it's plug and play to change.

My zenith r57w46 hdtv will not power up. i open the back and discover that one of the cap was burned. i could not get the size because of how bad it was burned. any suggestion

just make sure that the capacitor that you replaced has the same voltage rating and capacity. if still is just a clicking, you must check the regulator and FET transistor in the power supply board if get busted.

My Zenith air conditioner was not cooling, but had a 17050 Btu/h and was changed with 18,000Btu/h then the compressor was cooling at little pace and stops immediately. And could not start again unless you...

First, please check your compressor's capacitor for abnormality You can perform visual check on this part for deform. If nothing problem capacitor check the refrigerant pressure while running and current draw. Compare the reading with your manual. If it is not normal, you may have problem with dirt / clog up evaporator or dirty inside refrigerant pipings or clog up filter dryer ( if any).

Will not turn on

I had this same problem. Apparently it's fairly common with these older Hitachi Ultravision TVs. There is a bad fuse and capacitor. If you are willing to do some soldering it can be fixed at home. I bought a kit and instructions from for about $30. Although I haven't worked on electronics since jr high school electric shop, it powered up as soon as I replaced the bad parts. Not very difficult, although the circuit board accumulated an amazing amount of dust in its 10+ years of use.

We have several Zenith Presentation TVs in our classroooms that were recently placed there from a building that was closed in our district. Many of the tvs now will not power on. Whenever you hit the...

100uf,35volt capacitor is bad in the power supply. Take the back off. Follow the power cord to the main board. Straight in front of where the power cord goes into the board you will see a heat sink (tall metal) that has a transistor attached to it. Right next to the transistor will be a small capacitor about the diameter of a #2 pencil and about a 1\2 inch tall. There are only a couple of capacitors in this spot on the board, just make sure you replace the one that is marked 100uf, 50volt. Replace this capacitor and the sets will work. Let me know if this works, please. If it doesn't work, let me know the sets' model # and I'm sure I can assist you further. Have a great day!!!

I need codes for a Zenith Tv. Codes for a universal remote.

What brand and model remote do you have? each universal remote has their own codes for various tvs. Let me know your brand and model remote and I will see if I can find the codes for zenith from that manufacturer.

I have a high voltage problem.

I can get you the part number if you would give me the location # of the capacitor "Cxxx" there are probably 200 capacitors in your set so in order to get the right capacitance and voltage rating, you need to tell us which one your looking for :)
