Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television
A few days ago when I turned my tv on in the morning, the picture quality had noticably reduced, and there are now thin black lines spaced about 3" apart running horizontally accross the screen. Also, the approximate 4" space on either side of the screen (occupying the difference between 16:9 and 4:3) is of exceptional poor quality. The problem is the same whether I'm watching hd cable tv or an hd dvd, so I'm assuming the problem is with the tv rather than cable box or dvd. I'm getting no errors or warnings from the tv.
If it is tv a convergence problem, you should perform the convergence setting procedure illustrated in service manual, if this does not work the convergence board is faulty. To test if it is tv you can use a conventional aerial or a different box
If it is not tv then it can be a cable problem, or a faulty receiver box

It looks like either failing convergence IC chips or a couple busted capacitors around them. This will need to be given for servicing.
You could try a hard reset first though: Unplug the TV from the power socket, remove all cabling, wait 5 minutes and replug to wall socket and redo cabling.
However, I think that you could have either convergence problems or a failing power board, for which you will need to get the set serviced.
Hope that helps!
