Question about Zenith Z50PX2D 50 in. Plasma HDTV

A little different problem

Ok, almost a year after buying the tv from circuit city, the screen popped like everyone has mentioned so far & it was toast like everyone else says here. I did buy the extended warranty from circuit city a month before the 1 year expired and I felt like I actually did something right for a change, lol.

fast forward a year - actually 10 minutes ago. The transmission seem to "stutter" & displayed some weird blocks. Anyway, the screen didn't go black, instead the screeen went into a vertical type of way with yellow & pink lines. I am going to upload this onto youtube soon if anyone is interested.

I remember that the first problem was explained to me as the Y & Z sustain boards blew out. I don't know what this is this time, but I am concerned that I am screwed & I'm very very pissed. Like the rest of you, I'm sure you paid alot more than what you can buy this for today Nov 07. Anyone think they know what this problem could be?

Thanks, Rob

Hi Bill - thanks in advance for your insight. Could you direct me or email the tech bulletin that states all changes need to be made? I'm looking at the work order & they only replaced the Y & Z pcb's.

I think I'd be less jerked around if they knew that I'm in the know.

Again, thanks for your insight.
Rob

Rob,
It's either logic main or digital board and could also be one of those caused by a failing top or bottom Y drive. Hope you still have that warranty. That year ago when they replaced the Zsus p/n# 6871qzh044c and the Ysus p/n# 6871qyh039b did they also replace the Top Y Drive p/n# 6871qdh088a and Bottom Y Drive p/n# 6871qdh089a ?? If not they may have been doing you a dis-service... That is a common problem with Zenith and the tech bulletin clearly states that all parts must be replaced or the module replacements are not reliable and could cause other failures.

Rob,

Sorry, no, I don't have the actual bulletin just the several references from a tech program I have... Several have written in their comments regarding this repair that "...per Lg Upper And Lower Y Drives, Y Sustain, Z Sustain. Change All At The Same Time Before Turning Set Back On." and " ...MUST replace all four ... or the repair will not be reliable and most likely fail again."

I will see if I can lookup the bulletin.

Bill

My tv is showing plaid and I don't know why. It's refurbished. Help please anyone

Main board most likely-processes all signal to the screen among other things---refurbished sets are in my view are no bargain--they do as little as possible to get it out the door---years ago when I worked for Circuit City a very high percentage of failed sets were repaired/refurbished ones---buying someone else's lemons.

Most also come with a much shorter warranty as they really do not want to stand behind them very long.

My little 3 year old's temper caused the 42" T.V.

If you add in the labour required to install the replacement panel, it will probably be just as much as a buying a brand new tv. And the new tv would come with a warranty unlike the replacement.

You might have better luck looking in your local online classifieds for someone who is selling a tv of the exact same model. Most failures of these types of tvs are in the circuit boards in the back. Your circuit boards are probably still in good condition since it was just your screen that physically broke. If you could find someone with a cheap donor tv that has a good screen but malfuntioning internals (circuit boards), you could feasibly make one functioning set out of all the parts from the two.

Sorry about that, I wish I had better news.

Joe.

Polaroid tv 2700 dead

I have to tell you that I'm finding that this is about the life expectancy of the first generation LCD TV's. It could be fixed/repaired for between $100 to $200 at a good TV Service Shop.
You may just want to put that money into another TV!

Vertical lines across my entire screen

My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.
