I presume you've found the joey6p or website that discusses how to open the pronto and check the cables on the screen. If it's not a loose cable, then you will be forced to replace the screen. There are several post discussing a Samsung UG-24XXXXXX model screen as well as Replacement screens for the TSU 2000 on the first page (as of 02/22/05) of this forum. Did you read them?

FYI, SNL will work with the TSU2000, RC5000i, RC9200, RC5200, TSU6000 (any CCF-based remote), and the new NG models by using Migration Mode. (you have to import a CCF to PCF then merge with your PCF).
