Samsung Progressive 100hz SP43W64P picture has gone out of focus on Right & Left side of screen?

I will try to update the TV firmware first, you may log on Samsung support webpage to check is there a firmware update for your TV model & update it.
Also, you may go to the on screen menu to reset the TV to factory default to clean up the internet data buffer.

If you wish to get some details about this, check the site linked here. Adjustment to be done after lamp replacement to DLP TVs are given in detail. http://electronicshelponline.blogspot.com/
Pull up previous posts by its left sidebar, or type in the brand name and model number to of your set, to its search box, and press 'Enter' or view it in Mosaic / Timeslide option.

Press the 'pscan' button on the front of the recorder 3 times and the picture will come back. This is a little sod as you only need to catch the pscan button once - if your TV doesn't support a progressive scan your picture has gone....

Well, first the 100Hz issue. Your TV will display a descriptor or the signal it is receiving, not a descriptor of the picture you are watching. Your TV panel has a native resolution and frequency. In your case, that frequency is 100Hz. Everything, like it or not, must be converted to 100Hz for the TV to work. In your manual, you are simply adjusting setting which smooth the picture and make it flow better than it would at 50Hz. This feature is slight of hand and is probably working just fine. As for the picture fitting the screen; HD programs fill the screen of HD channels.... SD (Standard Definition) programs use black bars on each side when on HD channels. You can use any available wide or picture size feature your TV may have to stretch the picture. You may be unable to stretch the picture, due to restrictions (some TVs will not resize HD formats).

Some of these sets had problems with bad picture tubes; there is something you can do to try to correct this without replacing any parts.

You need to look very closely at the block to identify the focus versus screen controls----one row left to right will be marked Focus and the other row left to right will be marked screen------YOU need to locate the Blue Screen control(they are black like the block) With the set on(be careful) go to a video input with nothing connected---if you see a blue screen as well as the input number turn the BLUE SCREEN CONTROL SLOWLY TO THE LEFT UNTIL THE BLUE is gone.

If this cures the problem you may only be buying yourself some time----if the blue picture tube is bad sooner or later this trouble may return----I have seen sets where this was adjusted and the set worked for a year or more with no repeat of the trouble----replacing the blue tube would likely cost you 400 - 500 parts and labor.

You may have a bad blue picture tube but there is a way to deal with this first---This is a 2003 model ---I did one of these with the same problem a week ago---the set has a black plastic block with six controls---three are Focus(red,green,blue) the other 3 controls are Screen controls(red, green, blue) Someone has to remove the entire piece on the front of the set below the screen(usually a plastic part) most of the time it is secured with 3 screws on either side of the set in the back; once you remove the screws the entire piece should pull out(pull from right to left(it will not fall off or come out easy--it is held in with several large plastic pegs) With it removed there is an inspection plate with 4 screws-----the screen/focus block is behind it.

Sounds like convergence is off. Need new Convergence amps. Could cost a couple hundred. Check around. If it has an auto converge or manual converge try that first. Check menu

This sounds like a progressive scan issue (unit in P.Scan Mode) here is a C&P from the manual

Set "Alt Video Out"
Highlight "Alt Video Out", then press the RIGHT button to select
one of the following options:
• S-Video - Select this if you are using the S-Video OUT jack on
the rear panel to connect to a TV.
• Component - Select this if you are using the COMPONENT
VIDEO OUT jacks on the rear panel to connect to a
Progressive(480p) or Interlaced (480i) TV.
• See your TV owner's manual to determine what type of TV you
have.
- Interlace : Interlaced Scan mode will work.
- Progressive : Progressive Scan mode will work, and Video
and S-Video will not work.
• Press the Progressive button on the front panel if you have a
Progressive scan TV only. Otherwise, the picture will be
disturbed.

when you replace the convergence amp board. u usally have to go into setup. or service mode and manualy converge the set. these settings are what perfect focus basis it reconvegence on. sort of the factory settings. these faint lines may also be a red crt overdriving too
