Time for a new TV

Check the color level for that input. While monitoring the cable box go to the video part of the setup menu. Make sure the chroma or color is up to its normal setting.

Some TV sets have independent video settings for each input. This way each input can be separately set up.

There is a possibility something went defective thus causing the chroma processing to not work, but this rare. The menus showing in color are from a different built in circuit than the one that decoded and processes the program video.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

What you have done is change the input source. It will toggle through various modes like component, HDMI1, HDMI2, S-video etc., You should take a look behind the tv and see which input you have connected it into(usually HDMI 1 or HDMI2) then keep pressing the input button till it toggles back to that particular input.

Sai.

where is the video feed coming from? did you try a diffrent cable? can you change the channel at all?

With the cable splitter problem, I believe they used that idea to use the Antenna/cable A & B ports to watch digital and anolog TV.
Port A for Anolog and port B for Digital.

Best call Pioneer there may be a set up in the factory menu to change the sytems from PAL to NTSC
