Re: Samsung PN51E450A no picture/update
I replaced the mainboard and the tv powered up just fine. Seems to be working properly now!

Re: Samsung PN51E450A no picture
Would it be worth a try to replace the main board or the control board or is this most likely some kind of issue with the panel and I'm stuck with an expensive piece of trash?
Thanks,

Re: Samsung PN51E450A no picture
Ok, I disconnected the lvds cable and put a plain wire through holes 3 and 4 (see picture). When I turned the tv on I did not get the test patterns...just the same as before. Standby light blinks 6 times, goes out, and no picture.

I don't see any cracks anywhere. Also, I'm having trouble locating where the 3 and 4 hole are.

It doesn't appear the control board for this unit has the 4 pins sticking up to run this test. I attached a pic in case I missed something.

Ok, I inserted a picture of the back of the tv. I can include close ups of particular parts later today if need be.

Samsung PN51E450A no picture
I have a Samsung plasma PN51E450A1FXZA that will not turn on. The stand by light is on and will flicker 5 or 6 times when you try turn power on, but no picture will appear. If you wait another 5-10 minutes the chime will sound and the stand by light comes back on.
I've replaced the power board, XY board, and Y buffer. It still does the same thing. Could anything else be causing the problem...any ideas on how I should proceed? I do not have a multi meter.
Thanks,
