Question about Samsung HLP4663W 46" Rear Projection HDTV

1 Answer

Picture is much too big

I have a Samsung HLP4663w and the overscan on it is too much to take now. I adjusted the image's V and H values but can't seem to find a value to shrink the image slightly. Is there a way to fix this overscan issue?

Repaired the convergence and now the image quality is good but the TV seems to be over projecting the screen. The top, bottom and sides of the image are cut off slightly. is there a way to adjust?


Hey! its me again. I think what your experiencing is called overscan. This website might help but if not just google how to fix overscan on a projection tv.

Yes, if you have the original remote and get into the adjustment menu which is hidden you can adjust width, height, and centering if you want.

The jumper if it has it usually causes the color to look funny blue instead of normal.

It is located on the DMD board--the metal box on the light engine where the two plugs from the color wheel are.

It will be in a small opening on the metal shield that covers it--small and rectangular in shape--it has a small metal tab across it--it jumps two pins--

if it is there with a hemostat or small needle nose pliers pull it carefully out and see what you have--The CCA adjustments are done in the TECH MENU--look to see first if the jumper is there and remove it.

A lot of places that sell the wheel do not tell people about this.

The speed of the color wheel needs to adjusted or the CCA values. Both are found in the service menu . If you paid a company to fix the TV, call them and tell them that they forgot to perform these alignments. If you did the repair yourself, you'll have to call around for a price to have a Samsung service center perform these adjustments. I don't recommend consumers access the service menus of modern TVs because one wrong button push and you may cause irrepairable changes to the TV's proper operation.

Overscan is a staple in all CRT triple gun RPTV tech. It has to be taken in, if you want to see all of the picture possible in this medium. On ceiling mount front projection they have equipped them with all they need, they didn't need to do overscan, but with RPTVs this was not possible at the given price points. Overscan was necessary, to hide all the flaws out there at the edges, and they could not afford to pay their factory calibration techs to do it right, at the price points of the RPTV marketplace.

Unfortunately, when you take in that overscan, the picture gets hosed beyond belief, and then needs to be completely redone. It takes several hours and has quite a learning curve, a different one for each brand.

It is always available in my calibrations on all brands, but as an extra, at extra fees, to cover the extra time and experience/expertise required.
