Overscan. Please help

Hi, I have a 26 inch LG LCD TV hooked up to my ps3 via HDMI. The problem is that I get severe overscan issues with it at 720p and 1080i. I done my research and found out that it was fixable by going into the TV's service menu by holding menu on both the remote and the TV it's self.

The problem is that in the service menu, I don't understand any word of what's going. it really is very technical. My question is firstly, can anybody point me in the right direction on what to adjust to reduce the overscan, and secondly, weather I should even attempt it. I hear if you mess around in the service menu, you can really mess up your TV with no reset available.

Any suggestions on what I can do?

A TV's service menu is usually never meant to be accessed by the end user, so they are not made very user friendly. Having the service manual for your TV is probably necessary to make sense of everything, unless you have some specific instructions from somewhere else.

I had a similar situation a few years back, someone gave me a TV which had some bad convergence and geometry problems. I found the service manual on eBay and was able to use it to make some sense of things and fix the problems. As I recall, the menu used a lot of abbreviations and numerical values which were only explained in the manual. It is true that you can mess up your TV by doing the wrong thing in the service menu, so I wouldn't recommend trying to wing it.

Try searching around on the internet for the service manual of your model number. There are lots of free service manuals floating around in PDF format out there. If you can't find it there you could try eBay, or try looking through the service manual of a similar LG TV (the menu navigation and terminology will probably be similar.)
