the website for Sony Service Mode Info: NTSC Version, PAL Version
another useful website Service Mode
do note this website are for different set of model, but still works for DB29.
SERVICE MODE WARNING: Without proper documentation and training, you can probably do quite a good job of messing up your television set, perhaps even damaging it.
Don't mess around with the service mode adjustments unless you know what you're doing and have the service manual to guide you.
Once you enter service mode the first thing you should do is record all the original values BEFORE you change anything! - This is the only way to restore the television to its original (factory default) state should it become necessary to do so.
to enter Service Mode you have to press in your remote [PWR OFF] - [DISP], [5], [VOL+], [PWR ON].
the [DISP] button is the button that have the icon of [i+] and [?] in your remote. the button pressing timing is very important. press [PWR OFF] and wait for 1/2 second then quickly press [DISP], [5], [VOL+], [PWR ON]. if you done it correctly you will see some green line of number and character in your upper part of the TV.
now that you are in Service Mode, use button [1] and [4] to scroll next or back. when you found the setting that you want to change, use button [3] and [6] to change the value to be more or less.
IMPORTANT: I strongly suggest that before you adjust anything, you step through all the parameters and write down their current settings value in a piece of paper, so that you can undo any changes you make if you need to. Once the setting have been save to the EPROM, there is no way to find the Default Value back.
so far i have changed 2 values for fixing the left and right side of overcan. this are:
DEF2 014 HSZ0 000 --- to --- DEF2 014 HSZ0 -06 -for squeezing the pic
DEF2 000 HPOS 028 --- to --- DEF2 000 HPOS 030 -for moving the pic to left or right
with this change i manage to get the blue line on left and right in GRAW to appear.
Ray78 also found this setting to make wide screen stretch to become 4:3.
DEF1 VSIZ 039 -change the value to strecth or squeeze the pic.
VERY IMPORTANT: Getting back to the Before-I-Screwed-With-It EPROM defaults.
You can't. That is why you should write down all the default values as they are now
once we have change all the value now is time to save the setting to EPROM. the website tell us to press [MUTE] and then [ENTER]. but we couldn't find which is [ENTER] button.
pressing the [CONFIRM] button didn't works. Ray78 have finally figure out to substitute [ENTER] button with [0] button to make it works. 
VERY VERY IMPORTANT: Writing to the EPROM will allow changes to survive unplugging the set. Hold the piece of paper upon which you wrote down the old EPROM settings in one hand. (If you haven't written down the original settings, you can still return to the old settings at this point by turning the set off and pulling the plug.) With the other hand, press the [MUTE] button once. The word "WRITE" appears on the screen. This is your last chance to back out. Press the [0] button once. The color of the word "WRITE" changes to "RED". Your changes have now been saved to EPROM.
Please don't mess around with the service adjustments unless you know what you're doing! Remember, if something goes wrong, don`t save the adjustment! Just unplug the TV and plug it back in, and any unsaved adjustments will be restored to their factory presets. Also, the TV will be out of service mode now.
I strongly recommend that you get the SAMS or Sony service manual for your TV before you change any settings.
As you modify settings, record the factory preset values so that you may return to them if something goes wrong. Also, record your new values, in case they aren`t saved properly. Nominal values are listed below for most settings below. And, please, please, please, don't mess with the ID-x settings! These are different for every chassis, so the nominal values below won't probably be valid!
if anyone founds anymore setting to get a better display, plese post here so we can share2

). However its quite bulky and needs a lot of space to put it. However if u can, fork out another RM529 to get the matching tv rack.
