Are you totally sure it's 22 flashes, and not two sets of 11 flashes? The frequency of these blinks indicate a specific error, but the codes provided by Panasonic only go up to 12. It's likely the blinking sequence repeats itself, likely with a pause in between the two sets of blinks.

I spose it could be 11 as it flashes 11 times stops and flashes 11 times again

As far as I could find, 11 blinks means there is a cooling or fan issue, though it could also be a power supply issue. Try resetting the TV first. Unplug it for a full 20 minutes, then hold the power button on the side of the TV for 15 seconds. After that, plug the TV back in and try to power it on. That will rule out any easily fixable power issues. Let me know if that does the trick.

@sophiehall94 In that case, you'd need to probably take it somewhere to get it repaired or find a local TV tech. I'm not familiar enough with TVs to help you out here, and there isn't much information out there for repairing this model. Make sure you unaccept my answer if it didn't fix your issue.
