Same issue: PICTURE IS HALF THERE- WHAT TO REPLACE?
I got one of these from a frustrated owner and will attempt to repair it myself- I have a question as to where to start?
The picture appears, however, it comes on and looks like it's behind a black "smear" that eventually fades away (NOT entirely) towards the right of the screen. The picture that is there, is of poor quality and fuzzy. I have the TV hooked-up to Verizon FIOS connection.
Now, should I start with the Z Sustain board?
Does this describe something a tad different than most folks' issues of absolutely NO picture?
Does it point towards one particular part/fix?? Thank you for your assistance! :)
Re: Same issue: PICTURE IS HALF THERE- WHAT TO REPLACE?
I purchased the Z50PX2D in January 2006 in June 2007 I got the pop and no picture, cost 800+ to fix, now in July 2009 the same thing happened just got it fixed for 600+. Is this an ongoing thing every year and half or 2 years? If so where can I purchase the components so that next time I can fix it myself? That class action suit sounds really good to me, where can I sign up!!!!

Also, please review all component manufacturer's owners manuals ... Call our factory and obtain authorization for repairs BEFORE attempting the repair yourself ...... If thefifth wheel is hitched up with the front too high, too much weight will be.
this is not an operating system issue , this is a component issue and if the monitor on your laptop you can either order a new and try to attempt to replace it yourself or you can go to a repair shop and have them do it for you
TV fails to turn on, like the many other Samsung TV owners my three year
old Samsung TV began having delays turning on and then eventually
failed to turn on all together. I was shocked and dismayed to find the
high number of Samsung consumers with the same issues on the internet
and frustrated as like myself most were way beyond the one year
warranty. There are even several YouTube videos demonstrating how to
replace the faulty capacitors causing the problem. I was ready to be
done with Samsung but to my pleasant surprised after several phone calls
to 1-800-samsung they offered to make a onetime repair at no charge.
Samsung made the repair in less than 30 minutes with no questions asked.
Samsung stood by the product and so will I.
I have fixed an LG 42LH3000 with this very problem. Large TVs have a tendency to flex and bend ever so slightly when being moved or through heat, this can affect the connection of the ribbon cables at the top of the screen - either at the end where the Tcon board is or where the screen driver board is. When one end of the cable loses contact, half the picture goes (there are two ribbon cables. one for each side of the screen). Remove the cables then carefully reattach them. If you still have an intermittent problem would suggest leaving the screws out of the T-con board as this will give the ribbon cable more slack. Don't attempt any of this unless you know what you're doing - risk of damage to screen if handled indelicately also risk of fire when plugged back if the ribbon cables aren't secured properly.
I have the same TV built in 99. My problem is similar but the vertical hold gives out when the tv warms up about 5 minutes. I will attempt to locate the vertical hold circuit and replace any parts I suspects may be the problem. I suspect a cap is leaking or transitor around IC700 is degrading when warm.
You most likely have a convergence chip bad. In our shop, when we are working on projection TVs, we find that about 80% of the repairs we make are the same problem you are having. You need to replace the convergence chip ( there are 2 of the same chips on the convergence board, and I suggest you replace both ). If you are going to attempt the repair yourself you'll need to remember to use lots of heat sink grease so you don't have the same problem again. Also, try to get original parts, as there are times that the after-market ones don't work well. As a precaution, always remember to unplug the set from the wall before you do any work on the set. Good Luck
