This wall mounted TV came to me with owner reporting "blue screen". Its a 2012 model first used 2015. Turned it on and Samsung Smart TV logo came on (it does this every time the TV actually starts). Didn't have a source connected but in a few minutes all screen showed was multi coloured vertical lines. Turned it off and on and one time could just see the verticals although very dim screen (LEDs possibly off). After that just the usual click/click without response.
Laid it down to get back off and tried turn on, logo probably showed as leds turned on then off but no further response just clicks so pulled main board connector from power board, immediate reaction with leds coming on. So decided to pull and clean all connectors and this resulted in normal turn on with set running TV and also DVD via HDMI for hours over 2 days with normal turn on/off with remote. Thought I had the fix but on 3rd day as I activated channel change the screen turned green for a few minutes then coloured verticals then off with clicking again. Redid connectors today and set started normally so left it running coming back to it 20 mins later to see blank screen and clicking again. Tried restart and it did turn on every now and then itself but with varying verticals.
Have yet to take any voltages but suspicious of main board at this stage.
Boards are Main BN94-05570M (BN41-01800B), PWR BN44-00523B, TCON BN95-00582C (BN41-01790C). Just wondering if anyone has experience with this model and symptoms and would welcome comments. Search gives usual results with little in outcomes. Pics won't upload at this time will try later.
