"blotchy" picture on l.c.d. flat screen television

We recently bought a floor model of a flat screen lcd high def. television. there is a certain spot on the screen where there seems to be a "dirty" area...this is not noticable all the time, but more pronounced on lighter screens and flesh tones. We contacted Sony and the tech said to wipe of screen with a damp wet cloth. this didn't help. To me the screen doesn't appear to be smudged when the tv is off...but my husband says he can still see smudging. someone says if the l.c.d. screen is damaged this will cause the dark lines and smudges we see on the screen. if the screen is damaged does this void the waranty and if so, how costly is this problem to reapir? How CAN you clean an LCD screen? Thanks

SOURCE: smudge looking marks onscreen

If you suddenly noticed it, this is most likely caused by a large piece of dust on the lens. It is hard to clean, you would need to take the whole TV apart in order to get to the lens (mounted on the optical block).

It could also be caused by a failure of the optical block, which had inherent issues. There is a pending class action law suit against Sony for problems with optical block that include smudges, hazes, and tints that appear after a certain number of hours.

Other causes could be a dirty portion of the mirror or a smudge on the inside part of the screen but these are rare because dust and contaminants do not usually accumulate on these parts of the TV.

No picture on Samsung HP-R5052

Just a couple of things to try:
You say you tried another cable box and a roku. Are you using the same cables? Are you using hdmi, component or coax cables? Could be a bad wire. True high def tv 1080 requires an hdmi cable for the best picture. The next best choice is the component cable. This is a triple cable with red, green, & blue and provides 720 resolution. The least quality is the coax wire which will only provide low def standard quality picture. Sometimes people hook up 1, 2, or all 3 of these choices not knowing what it all means. If thats the case with your tv it may just be a matter of selecting the correct input on your tv with your remote. On your samsung remote there should be a button for input. Try pushing that button and make sure it's set to hdmi or component, whichever your using. If none of this, is it possible the plasma tv itself is defective?

Picture is schinking in on both sides

the picture is narrowed on the sides when you are not on a high def program.
commercials will often be standard def even on a high def channel.

check you cable or satelite box setting to "stretch" analog programming automatically.

Pixel solarization around letters and faces. 52" LED Sony I've tried adjusting the contrast, back light, and all other adjustments.

there is some interference with all flat tvs and it would be interesting to know is this in hd or standard def? in standard def the tv has to upscale the picture to fit a 52" screen and you will get this effect. there is nothing you can do, however this should dissapear in high definition.

Tv turns on and has sound but no picture. Only black screen, the menu from the cable or dvd cannot be seen.

Make sure your using a cable box that is compatible with a high def tv, if your tuning a high def channel and your converter does not support high def, it will only play the sound, no vidio at all.

Picture in high def does not fill screen

That is normal. Most HDTV's have a format or picture size option on the remote or menu. It will give you options like full, stretch ot zoom to fill in the blank spots. The problem is those settings can also distort the picture size so people look funny.

How do I adjust the picture to fill the screen

i was having problems in the tv menu getting full screen. no matter what i did there was two black bars on each side of the screen. i have att u verse so i went into the cable menu to options. In the options tab i went down to system options then to aspect ratio. in this screen you get a few options like 4:3 standard definition and 1080i on high def screen. I chose 1080i high def and then played with the zoom function on my remote and the problem was solved. hope this helps

Full screen view

in order to get the full HD experience you should be using HDMI cables. if you're using the white/red/yellow cables then your HD channels will not broadcast in full HD and you'll be stuck with the annoying black things around your screen

Only get 480p


Your friend is wrong you will get same resolution of 1080i whether you use component or Hdmi.
But you will need a high def input to tv in order to get this resolution EG high def cable box or satellite.
