Question about Zenith Z50PX2D 50 in. Plasma HDTV

1 Answer

Z50PX2D - I did not have the typical "Popping" Problem, nor have I ever had any Picture Problems. When I try to turn the set on, I hear the normal "Click", and the entire set is dead, standby light turns off and no power to the tv. Had the tv sitting for almost a year dead, then tryed to turn it on for the heck of it, and it worked, worked with continual use for 2 days, and this morning, "CLICK" no power again :( Can anyone tell me if this is either the Power Supply Board, or the Main Board? I would greatly appreciate it. Thanks so much!

    After more research, I have determined that it was the capacitors in the powerboard! I replaced the capacitors at a higher voltage, and the tv is working again (for now)
    :)
    To anyone else having issues, I highly recommend looking at the powerboard before spending any money either fixing or replacing the tv. Take the back off the TV and look at the powerboard, if any of the capacitors are blown they will be bowed out in the back (should be flat) Mine had 7 blown capacitors, all were 3300uf 10v capacitors. (Funny enough it was every single 3300 10V capacitor on the powerboard that blew out...)

    The fix cost me a total of $21!! And $15 of that was for both soldering and de-soldering irons. Through e-bay I got the 3300uf 16v capacitors for $6.50 (including shipping) I am hoping that the higher voltage will thwart this issue in the future, however only time will tell. If they blow again, I'm going to try 25v capacitors.

    I'm no tv repair person, and don't usually work on hardware issues like this (clearly by having to purchase the soldering

I own the same set. I had the "pop" happen to me. I decided not to fix the set, but before trashing the TV I removed all the boards and parts that I could. This included the Power Supply Board and the Main Board along with the Y Sus, Z Sus, Y Buffers, Speakers, Cooling Fans and few other things I don't know the name of. I'll sell all these parts $150, cheaper than you will find the Power Supply Board by itself. With all these parts you can fix the set cheaply no matter what ends up being the problem. Let me know if you are interested.

Popping sounds only during video/ you tube on tv from my computer.


Because of the amount of voltage required to run the older-style "tube" televisions, many problems, sounds and noises occur in tube televisions than in the newer, flat-panel televisions. Sounds occur for multiple reasons, with some being just part of the normal process these televisions run through in order to operate. On the other hand, some of these noises may indicate a problem with the television that could warrant repair.


Worn Insulation
Voltage against metal. Inside your television's tube, there are many wire parts that electricity runs through in order to make the television run. Usually, these parts are insulated with a rubber or foam casing that prevent the sound of the electricity. If the insulation surrounding these components is thin, weak, worn or absent, you are bound to hear buzzing, popping and cracking sounds coming from your television. While this may not mean you have to run out tomorrow and get a new one, the chances are that your TV's tube is working extra hard to make it all happen for you, and you may want to start pricing new sets for the near future. b> Static During Warm-Up b> Just like rubbing your feet on a thinly-carpeted floor can cause static electricity, the same can also build up inside your television. If the noise is relatively subtle, only occurring when you first turn it on, and not overly-disturbing, the chances are that the cracking and popping sounds you are hearing are just the television's way of warming up and getting rid of the unnecessary electricity. Bad Lamp b> Deep inside the heart of your tube television, there is a light-bulb fixture that makes the entire unit light up so that you can see a picture. If the cracking and popping sounds you are hearing tend to go along with the picture on the TV becoming unclear, it could be that the picture tube is failing. It is very difficult and costly to replace the picture tube on a tube TV, so this is an instance where you may benefit more from buying a new television than taking the old one in for repair. Hope this helps.

My z50px2d plasma tv had a loud popping sound and picture went totally dark. the green tv light remains on and the sound works just no picture. is it the bulb


I had a similar problem with my 42 in Philips LCD HDTV.



Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors. Many electronics companies were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.

1. Have it fixed by a professional

2. Open your TV and find PSB. Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


I have a tip/tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's called: Fixing the Philips Turns/shuts off on its own problem.


Hope this helps and Good luck.

My zenith plasma tv popped real loudlike a car backfiring and then the tv picture went black. power on green light wil turn on but it automatically cuts itself back off to the red light


There's an over current fault in the power supply or the Y-sustain convergence board. The loud pop was either a capacitor or pico-fuse breaking from excessive current overload. Sounds like 2 or 3 mosfets have shorted at the gate ends. Plasma TV's always have this problem because they generate too much heat and the components cant take the load conditions. Make your next TV an LCD...

To fix this problem have your local repair shop do it for you.....

any questions please ask.....

I heard a loud popping sound and the picture was gone. I can hear the sound and change channels but I do not have a picture


NO it's not his LAMP. It's a plasma, it doesn't have a lamp. It is a sustainer board. I'm not going to tell you which one to replace because there are several. Do some research. About 60% of the time it's the Y SUS board. That's what I just changed and I'm up and running. If you have played that game "Operation" as a kid or changed a graphics card on a computer you can do this. I had NO experience in electronics repair but took a chance and bought the part and put it in. Took less than an hour. All you need is a screw driver, needle nose pliers and patience. Good luckl.

Zenith Projection Tv Set Model number ZB4685T no Visual


Since this is a CRT based set, there could be a number of problems. What exactly do you mean when you say that the picture fades? Do you loose contrast and the picture gets lighter? or does the picture darken toward black?

Parts are still available, so this can be fixed. If youfeel you want to attempt this yourself, please supply additional info and we'll walk down the diagnosis path.

Sound but no picture


As a former television technician for a well known electronics store. This problem can be one of many problems. It can be a short of the main board, the y or x boards (either sus or buffer). But the most likely issue, since you still have sound, is that the panel went bad.

Possible problems: * The TV set may be unplugged. * A fuse or circuit breaker may be blown or switched off. * The remote control unit (RCU) may be disabled. Solutions: * Make sure the TV/VCR are plugged in and the wall switch is on. * Check the fuse or circuit breaker. Test the outlet with a lamp. * Replace the RCU's batteries: if this fails exchange the unit.
