Parallax 433MHz Receiver and Prop

MikeS

I have a BS2 located in my garage which is transmitting the Outside Temperature to an SX Receiver in my bedroom which displays the temperature on a 7 segment display. This set up has been working flawlessly since 2004. I now want to display the outside temperature on a TV in another location in my house. My first step to do this was to create a working spin program for the Spin-Stamp on a BOE, Parallax LCD, and a Parallax 433MHz Receiver. It uses the Simple Serial object to control the receiver and the Debug LCD object to display it on a LCD. This works great. When I tried to write a program for the TV I get very unstable and erratic results displayed on the TV. For the TV program I am using the Simple Serial object and the TV Text object. When I run the program I get three or four erroneous readings and then nothing is displayed on the screen. Do you think the Video frequencies are interfering with the RF Receiver or do I have something wrong with my program?
Both Programs are attached for your review.
