I do hope you can help. My husband inherited a 60in Zenith TV from his grandparents several years ago. The manufacture date was July, 2002. The television is a Zenith model number R60v26. Well early September of this year (2007) we turned the TV on one day and everything on the TV has a double in green. I have tried to adjust the convergence but the green does not adjust. The Blue and red I can move but it does not even give me the option to move the Green. We had a Television repair man come out to fix the TV, well he took all the info with him to get the replacement part. Well yesterday he gave us all our information
I have this same problem with my tv too, is it hard put put this part on or can someone that doesn't know anything about tv open and put it on?

Re: Z50PX2D 50 in. HDTV... Problem
You have a problem with the STK convergence modules. They're on the
center circuit board attached to an aluminum heat sink that's about 8"
long and 6" tall. You may be able to recreate the problem (hour glass
effect) by gently moving the heat sink (which the modules are connected
to). This gives the hour glass effect on the picture and the advanced
convergence screen. This is an indication that the modules pins aren't
solidly connected (meaning soldered) properly. Remove the circuit board
and clean the old solder off & resolder the modules pins to the
circuit board reconnected the board and then retest by again pushing on
the heat sink. The "factory" job was good enough for 3-4 years
but the heat (and these modules do create a lot of heat) and stress
created from repeated use eventually takes it's toll, weakens the pin
connections and our problem occurs. take the appropriate cautions
working around the high voltage of the set.
If soldering doesn't help, then the modules have died and need
replacing. Don't buy the $10 cheap ones. Most of them have
an upgraded version that is stronger. Also look for any burned
resistors in the vicinity of the modules.
Best of luck, hope ya fix it.

Problem with the Zenith Z50PX2D 50 in. HDTV Plasma Television
While watching, TV made a sharp bang sound. Sound still good, channels can be changed, but no screen, now tv wont come on at all?
I would have to say that you have bad capacitor in the power supply.Have you taken the TV apart?If you can take it apart,and send some pictures of the board with the power cord going to it,I can tell you which capacitors if any are bad.They have a rounded top to them instead of being flat.Also,how many blinks does the power light blink?Usually it's a series of flashes,and then it repeats.I hope this helps.Thank You very much!
Try this link to zenith it should take you directly to the Product support page. Click on Product Support in the menu bar then click on the owner's manuals link on the left side of the page. You'll want to select TV as the product group, then PDP TV as the product, ENGLISH for the language, and finally type in the model number.
Technician just replaced the upper right (from the back) circuit board that conects to the panel. TV now works fine. I bought the display model 8 months ago with extended Circuit City Warranty for $1000 so I can't complain. This was covered entirly by LG/Zenith (nicest Cust. Svc. ever) so we'll wait and see what happens.
Check your input connections, especially the HDMI (if in use). I have found through personal experience that the weight of the cable and any small vibration can be enough to loosen the connection and leave you a blank screen. The manufacturers would have been smarter to have all the inputs face toward the floor at the bottom of the set (like the power cord). Anyone who has mounted their set to the wall will understand what I am saying.
That being said, you may be better off saving your money and buying a new LCD TV. The Zenith sets have proved to be a ticking bomb. If you Google "pop" and "z50px2d" you will read a number of posts on various boards that indicate that the Zenith plasmas have about a 2 year life expectancy before they are in need of some very expensive service. And frequently even after they are serviced are prone to further failure.
Someone pointed out to me not to long ago a valid fact: LCD technology has been around since the pocket calculator and therefore much less prone to unexpected failure than the relatively new plasma technology. I just wish someone had told me that 2 years ago when I ponied up $3000 for my Zenith z50px2d that blew out a few days ago.
