I have a Samsung LCD TV which recently got serviced. After it got serviced I start getting the IR interference for the first 5 min after TV has been turned ON. During that time I cannot control my Dish receiver. The receiver can be controled using the RF remote. Can TSU7000 send RF commands?

It looks like the IR interference occurs because of the "LCD's backlight". What is the "LCD Backlight" and is there a way it can be controlled?

Is it possible to fix IR interference?

Anyone know what UHF frequency does Dish ViP622 receiver uses? Is it 433Mhz or 418Mhz?

Thanks.
