Wavy picture with a lot of red, perfect focus states no sensor data

System was built and purchased in 2003. I was working great without warning it started having a wavy picture with an outline in red. I tried different things on the menu the main problem that I noticed is the fact that the perfect focus does not respond and states no senser data.

You have a bad sensor, a bad digital convergence board, or the new board is not working correctly. I would start by swaping out the convergence board or exchange it for another one. Good Luck

Have a 2003 cadillac cts my car will crank but not turn on some times it will start but i will be driving and get to a red light and it will completly shut down on me it does not always do this at times it...

how many miles are on your car ? will it start up after it shuts down or do you have to wait 20 or 30 min. had a problem like this with my own car it had 1600,000 miles on it. do you have any warning light on dash when this happen, if not, it's most likley it is the crank position sensor. it's about $60.00 at the dealership, not fun to put in. also could be a fuel pump problem, have a pressure test done on pump first before you buy a pump it is about $400.00 + $600.00 to put in. I haven't seen to many pump problems without a lot of other issue while driving. If warning light are on, have the computer scanned first.

good luck bro,
i have done many CTS's like this and all turned out be the sensor.

Three intermittent warning lights

I would think a sensor is going bad , but ,without testing that is just a guess , just like the dealer tech , assuming it's a module or a fuse ! With the light's on checking for DTC'S - diagnostic trouble codes would be a real good first step . The dealer tech should have hooked up the Tech 2 scan tool an checked codes an look at sensor data parameters ....
