Re: Samsung 50" Plasma PS50A556S2FXXU
y-board meaning the y-buffer, the most common fault.
But I believe this faulty tv has a bad display. Iv shown the images before of the ghosty white effect, which is difficult to see in this first picture, but look at the following pictures, which show it more clearly once removing the power to the pcbs that run along the bottom of the tv....
Ignore the vertical lines they are present due to disconnecting the bottom pcbs.
Now whats seriously annoying is i sourced a display...Leave a comment:

Re: Vizio 32" Plasma question
Sounds like a short once something is switching in.
Is it the buffer board y or y sus main? If you can get hold of a new/second hand pcb and try it, thats the way id go.
Are you uk based?Leave a comment:

Re: Samsung 50" Plasma PS50A556S2FXXU
I see, I got loads of service manuals but not one for this tv, It gives me an idea though.
All they do is replace y-x-z. So a service engineer has these full set of pcbs(in an ideal world!) and just swaps them out.... job done in 15mins then.
I prefer the component level fault finding too, il try with these pcbs doing ohm test comparisons.
Wizard what do you think of what looks like a burn on a ribbon cable going into the Xmain pcb?
Also I have 6 going into this xmain - what do they actually...Leave a comment:

Re: Samsung 50" Plasma PS50A556S2FXXU
Well my new pcb arrived quick, and thats made no difference :-(
On the Xmain I found this on one of the ribbon cables (in line with my two faulty horizontal lines, looks like a small burn? :
Thats on this PCB the other side of the tv, when I pull the top one I lose a small part of the top of the screen, the second one down fills the 2 black lines together. So that sounded normal, untill I pulled the 3rd and nothing, 4th nothing, 5th nothing but 6th I lost the whole bottom half of the screen...

Re: Samsung 50" Plasma PS50A556S2FXXU
What do you mean "ohm the buffers" and go after the y board?
I can get a y board for £36 to try it i guess [url]http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250647320834&ssPageName=STRK:MEWNX:IT[/url]

Re: Samsung 50" Plasma PS50A556S2FXXU
Both lines are solid to a point (see tape marking end of solid line, left to right), the picture isnt too clear, you can see the top line, basically the bottom is the same.
Any help much appreciated.

Samsung 50" Plasma PS50A556S2FXXU
Hi Guys
I have a problem with my Samsung PS50A556S2FXXU
I have two horizontal 1.5" black lines runing through the top half of the screen.
They are not ghost black lines but solid lines.
Im quite competent in electronics repair, id just like to know if im wasting my time with a faulty display panel before I start fault finding the electronics.
Hopefully some one can help start me off.
Cheers
Alan
