REAR PROJECTION TV SCREEN GETTING HARD TO SEE

We have a Sony KP-43HT20 CRT rear projection TV. This was purchased in 2002. The picture seems to be getting dimmer. I was told we could replace the bulbs in it, but I was wondering what the average lifespan of the CRT rear projection TV is so we can decide whether to replace or fix.

Main screen showing "no signal"


KP-43HT20 has 2 tuners, one is main (TU2) and 2nd is called sub tuner (TU1). Both tuners are mounted on A board located on right side of TV.
In my opinion, main tuner (TU2) is not working and causing No Signal message.
Let me know if you want to repair tv by yourself.to provide you more technical info.

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.
