Samsung DLP HL-P5674W Screen is stretched at the top and bottom...
Last week, my Samsung DLP started to cut off the very top and bottom of the channel display. It's almost like a 60 inch picture trying to be dispalyed on a 56 inch TV. Color and sound still look great and the right and left sides of the display are fine, but channels like ESPN that run a "tickerbar" at the bottom of the screen do not look right. I can see the very top edge of ESPN's tickerbar, but no details. I have tried adjusting the picture size, but the result is the same.

Here is Fan part#

Light engine assembly has to be removed. This involves unplugging various connectors between processing/control chassis on the left side and engine assembly on the right side. Mounting screws on the top and bottom of engine assembly. Then remove light engine assembly completely from the TV. Fan#2 is the lamp cooling fan and is located beside the lamp assembly.
It is not too complicated if you draw a picture of where all the plugs are removed from. If one plug is not put back correctly, unit will not work. Usually a tight fight sliding out the engine. Plastic cable tie-down between the 2 assemblies can be cut and discarded, this makes re-installing light engine considerably easier.
Cheat the cabinet safety switch with tape or stretch connecting wire across it to hold it in "on" position for test after reassembly.
Service cost may be $150-$200 if you don't do it yourself. We do it in most Canada cities.
A DLP Lamp will fail in two ways. 1.The glass tube housing the filament will shatter and the TV will not turn on. 2. The lamp has many hours of use on it and will gradually grow dimmer. At no time will the lamp cause any picture defect. Check your Cable or Sat box for the correct aspect ratio as well as the TV aspect ratio. Chances are the aspect ratio in either system is set incorrectly. If the gray borders are uniform then the aspect ratio is not set properly. If this occurs on certain channels but not others then the particular channel is broadcasting in the 4:3 aspect ratio and there is nothing wrong with your set.
color wheel is failing and this repair cost thousand or more most of the time so i guess it would be better to dispose of or you may get lucky and find one on ebay but make sure you take care in installing
You may have already done this, but check to see if you can change the screen size in the set-top-box settings and set this to widescreen 16:9 to match the tv. You may also have 14:9 as an option too. Also, check your video output settings, this can be changed between RGB, Composite, PAL or NTSC.
Let me know if that does or doesn't solve the problem
