I have read in panasonic lcd training manual that company built in self testing mode in this Series,Its have self pettren generator to test panel,Now my Question is did any one know other brand self testing method of panel like panasonic?
PM me if you want to get panasonic test code.
You mention external device to test panels in your web link..
Now i know Panasonic Lcd tv self testing method of panels,The panasonic panel have built in its own pettren generator,you can use it with just secrat commands input.
Hi, What do you need those 'secret codes' for? Pattern generator software is built- in on T-con boards or logic boards for plasma displays. No 'secret codes' or silly toys (like laptop screen testers) are necessary in establishing fault diagnosis unless you are an absolute beginner. You can run auto gen modes by setting up a jumper on CTRL b/d or else shortening two pins together.
Besides Panasonic faults will not be manifested visually (unless you have a duff screen) as the micro chip interrogates almost everything, thus a set goes into shutdown and all you see is just blinking codes.
Panasonic have a feature of free run self testing of panels method as i mention before.And i know the method of panasonic.How many people know the other brand self testing method of panels?Its help when we confiuesd regarding the fault is whater panel or tcon fault,.. its help when we see problems like H lines,V lines,Mix lines,Distortion image,circles in image etc.

You are wrong mate:
1) This won't tell you whether it's T-con or the panel because T-con is the part of the panel already So this is one. To work out whether T-con or the pixel panel you need some voltage/signal measurements, some experience and observation skills, if you send me the picture/movie, I will tell you which one is faulty.
2) The Panasonic method of testing is used to figure out whether the pixel panel with T-con is bad or something before (signal A board and its peripherals, PSU etc.)
Nice to see you again my friend
There was a basic issue you know in LCDs,faulty panel or faulty tcon board,some times both are faulty at the same time,Did you share us and Contribution of repair mechanisms to determining knowledge of lcd faults?
Sorry for bad english
In simple words can you share your experience with us?
Put up some photos and cure?
Sure, I can. /No problem about English/ But as I said:looking at the pictures and diagnosing panel faults by just seeing the picture of the fault is only 75% correct, you need to take some critical voltage tests on T-con board first (in some cases) as this is forum for advanced technicians or servicemen. Your posts may end up in the bin if you post up pictures of faults only (forum rules and rigour)
yes you are right but ratio is 50% when ever you saw faults like this as i mention in my post,no one can say that i diagnose 100% by seeing the picture,People like us gather here for contribute our experience regarding the faults.For me i respect all members of any forum in web.
