AU Optronics Taiwan

This company claims to be the biggest LCD LED panels supplier across the world - Samsung, Sony, LG, Panasonic, Phillips, Vu, TCL etc... Etc.... all get their panels from this company. How true is this?

They make a lot of monitors so possible

They make monitors. Most TV panels are either made by Samsung display (not the same company as Samsung visual display which makes the TV), LG display and BOE.

Well ,then things have changed. A decade ago they used to make TV panels . At the time Samsung used to source panels either in house , from AUO or a third company . Used to be quite a debate here at the time

I own a 2008 make Samsung A550 LCD tv. It was a popular model and it was released with S3( Samsung panel). The one I purchased came with an au optronics panel(identified by serial and batch number) which is considered as a step below in quality but quite un-discernable unless viewed side by side. Towards the end of tv lifecycle, Samsung supplied with a chi-mei panel which is again one step below au optronics. Companies routinely do this to cut costs as part of six sigma kind of quality programs. The objective is to reduce costs and increase profitability without being very obvious to the customer. Manufacturers have this standard disclaimer that specifications are subject to change based on availability etc... This is just one example that I closely followed.

As of today the Tv still works perfectly. on the other hand, I have a TCL/ Iffalcon tv that has panel failure within 6 months of purchase.

How did you find panel details using batch and serial numbers? Is there any website that helps you identifying the same?

There are different forums for that just google "Decoding Samsung panel types"
It is not straightforward. The information that I gathered 12 years ago to validate may differ to current standards. Service menu is one way to know what's really inside.

Are there guides/ cheatsheets on accessing the SMs?

Each tv model will have a specific key sequence to access the service menu just google it. I advise not to get into it because if you change any wrong parameter it will not be easy to backtrack and you may need to run to the service center to have it reset.
