You can change the input by using the source key on the TV control panel. As for the black lines, It is due to loose connections on the panel and it may be difficult for you to try to correct them. Please consult a good TV Tech to do this for you.
Write down your serial # (found on the back or on the side) and your model # and call 800-Samsung. The issue has to do with the capacitors and if your TV was manufactured between Dec 2007 and May 2008 they will send a repairman out to repair for free (one time only). I just called and they are sending someone out to repair mine. Apparently there are tons of people experience the same problem.
this sounds like a scan board gone ,, if you check ebay youll see two things,
1, other tvs for sale with the same fault (It might give you a clue to the fault ie , which board )
2, the same tv as yours with a broken screen ,
i dont know how good you are with taking things to bits but i personally would buy the tv with the broken screen and start swapping over the internal boards ?
Have you checked your home insurance policy for broken tv,s
it may have fell of its stand when you were'nt looking?
This problem (known as sparkles) can be cured by adjusting the ramp control on the Y-Sustain board. If this does not cure the dots then there is a software remedy for the control board which an LG repair centre could fix. Failing that a replacement board is required. The orbitor & whitewash are like screen savers to help to prevent a screen burn from a permanently displayed image.
I too have the same problem with the blue screen and also some dots in the center of the screen. I went to the sony site (www.sony.com) and found the answer. They will repair the unit until Dec 31, 2008. hope this helps
If you notice these dots when you use Video or HDMI inputs, then you need to do something to get rid of them.
Open the back cover, try to reduce the Vs voltage 5-10V below its spec value. Vs is from Power Supply Board and its spec value was printed on the back of PDP panel. If your tv is under warranty, just drop it to the warranty depot shop.
