Question about Zenith Televison & Video

2 Answers

I have a 1989 Zenith System 3 TV that has never given me trouble until today. I used the TV last night ( it is in my bedroom). This afternoon I went into the bedroom and... The green stereo light is blinking (?!), but the TV will not turn on or off. Unplugging it for hours and hoping it will reset itself is not working. Other than declaring it dead, are there any suggestions?

    Two heads are better than one. Perhaps an expert has rrun across the same or similar problem.

    Dear SD Tech,



    Thank you for such a concise, understandable, and well written answer to my problem.



    I have a certain affinity for my 21 year-old Zenith System 3 television. You see, I won it on a game show. And not just any game show, but the first game show ever broadcast on MTV -- Remote Control. It is the last surviving (so to speak) prize I won during one the the most fun days in my life.



    Even though the the set is now old enough to purchase alcohol, it has served me well and been a companion on my journey from a graduate student to a mature, but NOT 60 year-old, woman.



    I guess the true "fix" to my problem is to become a contestant on "Who Wants to be a Millionaire!"



    Thanks again,

    Maureen Sears

    I doubt that any television I may purchase to replace the old gal will last another 21 years.

First came the Chromacolor, then the Chromacolor II, and then the System III sets; I know as I worked on hundreds of them from the 1970's on.

The real problem with repairing them is they were designed as a modular set with 90% of the parts on replaceable circuit boards. Some parts were available separate but for the most part it was replace a board. I over the years have fixed many without replacing a board--it depends on what is wrong.

Most likely is the Deflection board is where the problem is---most common one to give problems.

The shop I worked for the last 5 years did see some of these come in for repair and I got assigned most if not all of them as the other techs had zero experience with them.

Most of the customers were older people who did not want to give up on the set---repair of these sets presents two problems----one: most of the boards are now hard to get and two: the set is of such an age that you gamble spending money to fix it and a few months from now something else fails and the part needed is no longer available.

If I was looking at this set I would check the horizontal output transistor first---if you are lucky it failed----shutdown will happen instantly and unplugging will not cure it.

If you cannot attempt this your only other option is to check shops in your area and see if any of them will ATTEMPT a repair on a set of this age.

I like the older sets as they last a lot longer than the new ones---but at some point it becomes a economic decision.

Let me know the full model number of the set and I will try to research it to see what if any parts are still available for it.

I am here to help.

Regards, SD TECH

Hi,

Wow!! 1989, that's a Long time. So, there is no Point in Repair, However, let me inform you, it seems that it is a Power Supply Board Problem.

Open the TV and look for Power Supply Board. Once you find the Board, Pull out the Connectors. Take the Board out. With the help of magnifying glass, you need to check Cold Solder Joints.If not, then Check the Caps and Fuses. I imagine, if this could be due to Power Shut Off, you would be able to Find Some Bulged / Swelled / Leaked Caps. You would smell Ammonia kind of odor. You need to pull them out. Order the same Caps online or go to Radio Shack. It would cost you few bucks, in fact less than 20 bucks. Once you get the Caps, solder them and it is all set.

Note - You need to take all the Precautions as this would involve Voltage.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

The furnace is 10yrs old in a house of the same age. We added on a new 20 X 20 bedroom 3 years ago. Since then the furnace stops when the temp gets below zero which is usually at night. The next day...


Thanks for the information you gave, however you did not tell us the make or model of the furnace. Try removing the air intake and use room air for combustion. Plug the pipe leading to the outside so no cold air enters the home. If the system runs flawlessly, you have an issue of moisture being sucked in the intake and freezing. If you can whitness this, there should be an error code that will blink on the circuit board. Most newer furnaces can vent up to 50 feet or so depending on model. If you post again, let us know what brand you have so we can help you more.

Good luck!

The picture freezes and the sound is lost. Until the picture returns and the sound returns,this happens every couple of seconds.


If you actually have the Zenith model TV (B25A24Z), the trouble is not in your set. This model has only an analog tuner, and what it sounds like you are describing is digital pixellation. This is what happens with a digital-to-analog converter box when it gets a weak signal, with rain fade or heavy snow on a satellite dish antenna, or when a digital cable system has some signal problems. The converter equipment locks the last complete frame (or breaks up into blocks and freezes) and the sound is muted.

You'll need to look for the cause of your trouble in whatever is feeding the TV. If you have a digital converter box for off-the-air broadcasts, make sure you have a good antenna and all the connections are tight. If you have satellite TV service or digital cable service, you might need to contact your service provider for help in troubleshooting and fixing the trouble.
