The projection IC's are bad. You can't do this yourself and would probably cost $300 - $400 for a tech to do it. Start shopping.

TV showing Red shadows when viewing the picture


Open the TV set and at the end of the CRT, there is a Circuit board (Video baord) where color adjustments are manually done there. OK, normally there are cracks or cold solders on the terminal of the components which can be the cause. You'll need a technician to do the re-soldering of the terminals. cheers.

Sony KP-43HT20 Projection TV


5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.
