Question about Samsung LTN226W 22 in. HD-Ready LCD Television
I have 4 of these units with essentially the same problem, but to different degrees. Using the s-video or rca inputs (component and dvi not tested) I get sound from my source but I can barely make out the picture, same problem when accessing the menu. The screen is bright, so I doubt it is a back-light issue. On the units where I could see well enough, I adjusted contrast and brightness settings with no success. I bought these 4 units at auction, and there were dozens more with the same listed problem. Do you think these are worthy of repair? Thanks
Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.
In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Replacement of T-Con board is only test for it.
There is no voltage data or other info available in service manual to confirm t-con board.
Required T-Con board is available in discount-merchants.com for $50 and if that does not solve over bright picture problem then lcd panel (screen) is bad and it will cost approx new tv price.
