Here is a question for Richard and perhaps others. One can see posts in other forums where people have callibrated their HDTVs and have given step by step instructions on how to do your own callibrating (beyond the basic stuff in AVIA). One is certainly tempted to save their money and do it yourself, sort of like fixing your own motorcycle so to speak. But what are the dangers?

I haven't seen what everyone is doing, but if you don't have the equipment to generate the proper test patterns and you don't have experience doing this on different TVs - how good a job could you really do?

OK lets say there are intructions on how to tweak in the service menu. The instructions are for your exact tv you own. You use the same values as the instructions say. Would you see the same results? If you have 2 identical sets would they actually be visibly identical. I would think not. I am sure there alot of variables. I am not going to try this, just wondering what would happen if one did this.

This method would not produce the best picture for most types of RPTV's, i.e. CRT.
Where you see this method being done is mostly with DLPs. This is because a calibrator noticed that there wasn't that much variation in the SM values for a large set of DLPs that he calibrated. So for a much smaller fee than an in-home calibration, he sales the SM value averages that he has collected from his other in-home calibrations of DLPs.
This results in a very good calibration albeit not as great as an in-home calibration. But for the savings, it may be worth it.

This is like amateur surgery. The only difference is no one dies. You have to have the right equipment and know how to use it. The equip. runs thousands so how can you save money.

Because the only equipment you need is the remote control that came with your TV in order to access the Service Menu (SM).

Now if you want to calibrate the TV yourself with actual calibration equipment, then you can rent the equipment. For about $300 you can rent the ColorFacts calibration equipment and you have a month to calibrate your TV yourself.

Well, not quite. This is a uniform disclaimer that should be on all that free info you are finding you are finding out there.
Service access is intended for authorized service centers and service providers only due to the ability to easily create malfunctions and render the product useless. Digital displays are even more susceptible to this problem where you could lose the picture altogether or prevent the display from turning on requiring the product be returned to the factory to have the data
reinstalled. Access to this function could void your warranty. This forum is not liable for any damages due to the information provided.
It is amateur surgery. Because like Hugh said...
>>You have to have the right equipment and know how to use it. The equip. runs thousands so how can you save money.
Not only that you have to know what a correct image looks like and that is the biggest problem of all.
The best most can hope for is an improvement. There are few that will be able to correctly address all variables, calibrate the product correctly and provide quality imaging solutions. All calibrators have spent 100's of hours working to understand the above.
>>Because the only equipment you need is the remote control that came with your TV in order to access the Service Menu (SM).
To change the data yes. To determine if you are getting the correct results you need the other expensive equipment.
>>For about $300 you can rent the ColorFacts calibration equipment and you have a month to calibrate your TV yourself.
That is only recommended to hobbyists who want to calibrate the display themselves. For most you would be far better off applying the $300 towards a pro who already has the equipment and experience.
