You cannot replace 1SR153 with a 1N4148. Attempting to do so will likely result in flames, fire, damage, etc.

Re: A guide to fixing/troubleshooting some common plasma TV problems
Hi guys.First of all i apologize for my english ,but i will try to explain my self to be understood.I have a plasma Panasonic TH42PX80E and the power supply is broken.I give it to someone to repair it and his make,s test on my supply also missing some parts. Now i try to restore it,because i find one identical power supply and the tv is working.The power supply is LSJB1260 -1 ,the pieces are D416 (1SR153) i wanna replace it with 1n4148 if is ok, and D411 (ST02D-170) with this i have a problem because is not available in my country ,unless i order for 2014.The D411 is a 2 component piece one zener +one fast diode. So what do you think that i have to buy separately to build this overvoltage diode? If you wanna see the datasheet for St02d-170 you will find them in pdf in SHINDENGEN site which build ,it.Thanks all.

Looks like a bad Y-buffer. Common issue with these is shorted FETs.

IPM replacement would probably fix the Z-sustain.

Re: A guide to fixing/troubleshooting some common plasma TV problems
Hi all,
I have a new plasma, a Samsung PS64F8500, and it has an annoying problem and I'm at my wits end trying to figure out what to do about it, so I'm asking here.
Firstly, the unit is factory refurbished. The first unit I received had exactly the same problem, so I returned it, and the replacement has the same issue (although much less severe). The problem is this:
In darker scenes, the top half of the screen is ghosted onto the bottom half, in a flickering manner, adding to what is already there. On the first panel this happened fairly consistently, however on the 2nd it happens only after the TV has been driven pretty hard for a while (ie, after watching a 3D movie, or when used at full brightness for a long period). Note that it does NOT happen in 3D mode at all, only when switching back to normal 2D TV, and only when the screen is fairly low intensity. I've put an example on YouTube, the quality is pretty terrible but you can see the doubled image at the bottom of the screen. The problem occurs regardless of input, and in fact occurs even when all inputs are disconnected and it is just displaying menus.

The fact that it only occurs after a bit of use (at least for this panel) seems to indicate it's a heat issue with one of the boards, but it's strange that it's exactly the same problem with both sets. Any suggestions to fix this thing, or should I return it again and ask for another replacement? The retailer is extremely difficult to deal with, so I really don't relish the though of going through the whole replacement saga again. The retailer claimed that the panel had no issues at all when it was returned, even though the first panel was truly horrible.
Thanks for any help you can provide!

I've started a new thread as I've uploaded some pics.........
I'm thinking positive!

Re: A guide to fixing/troubleshooting some common plasma TV problems
Hi
I've checked the model number and it's as follows:
PDP42TV006 42PLCTV100SAM
Hopefully there's one or two cheap & simple things I can try first but if the worse case happens and I'm looking at having to replace I've been told that Panasonic, Samsung, and then LG is the order I should be looking at. Does that sounds right to you?
Many thanks
Fritz

Not a plasma. Keep questions in your own thread please.
