I have a 42" LCD TV Brand: Hannspree Model: HSH1102 Product: ST42DMSBUFH4S The TV works fine for a while, only sometimes the image starts to get some lines and very quickly turns black with the lines as shown on image:
...for about 30 seconds, some times it continues like that and sometimes it goes black with a few lit pixels moving around and I have seen it go back to normal a couple times without doing anything.
The issue gets resolved by just turning off and on the TV, I don't have to wait any time before turning on which tells me it is not a heating issue I have tried hitting lightly around the screen while its having the problem, no change When I unplug from the all while on, turn back on...image goes to normal and stays normal longer I've noticed
Has had the issue with all inputs (HDMI, RGB, Coaxial) I haven't found a pattern that would replicate the issue ... (perhaps messing with inputs or changing channels rapidly) So I wonder If changing the T-Con Board or Main Board or what would correct this issue.
Thank you in advance for the help
