Dead Power Supply ?
Check to see if the fan is spinning ?
Make sure you have it connected to the Video OUTPUT.

My sims svr 130 lose the driver, where looking for the driver?

It sounds like you need a new hard drive. I'd recommend you visit this TiVo repair website.

Hi-I have one also-great detector-probably the most complicated one I've ever had! Possibly you are in battery saver mode which will turn off 1,3,6 hour increments! About the 14th time on menu you will see B SVR ON at that time push the Q button to inactivate the battery saver mode-should show B SVR OFF. John

Hi. That's pretty dated, nearest driver I could find is over 10 years old. Nothing to lose trying it:
