Hi all,
(Sorry for long detailed post)
I hope someone could help me out? I have a SAMSUNG PLASMA 50INCH PS50Q7HD which I bought secondhand 4-5 weeks ago. The t.v was a spares & repairs job (£40) and I understood at the time it had no picture... But it had sound. I purely bought it as I have fixed a few smaller tvs in the past.
I did a bit of research before buying it and read on the net it was probably the Ymain & buffer boards faulty and a quick look on ebay prompted me into getting the tv as spares were available. On getting the tv home (after buying it) I decided to switch tv on and within minutes there was a small pop and a little smoke came from the top right of the set.
After letting the tv power down for an hour I decided to take the back cover off and have a look...I quickly discovered that the Ymain board had a few blown diodes which indicated a problem.
I also read that as a certain section of the Ymain diodes had blown, it was likely the bottom buffer caused the problem......... It seemed an easy fix!!!!
I ordered a new Ymain board and a "Pair" of buffers from Cradeal.co.uk which arrived today! I have now fitted them to TV. Unfortunately I still only have sound and NO picture........ which was the original problem!
I really am back to square one!?!
The set now stays on with the sound coming through nice and clear!
There is no image, no flecks, even if you press menu... there is nothing!
I had checked all VS and other outputs and they all appear to be fine. I have seen other test on Youtube and my VS etc are within the 2v range.
The TV cost me £100+ and the moment
Any advice would really be appreciated, as this is the second package from cradeal after they sent the wrong parts last time??!!
I could ask Cradeal for a refund on the lot if the Ymain and buffers should have fixed the problem, as they could be faulty themselves I suppose!
I even tested my old buffers before replacing and I was never convinced they were faulty as I could not get them to fail in Continuity test. I purely replaced all 3 boards as Cradeal would cover the lot in 60 day warranty and following other people advice. To me it made sense to buy as a package.
Like I said before I could go for a refund, but I prefer a fix!
I sure you guys understand
