The bulb is fine but it still has no picture and blue and red lights are blinking
The problem you are describing doe not seem fan related. I would recommend a servicer to inspect your TV internally

I have the same type of TV, and I think it has a filed "power rail", as the LED does not burn at all, nor do the heaters of any of the CRT's. When I plug it in, I can hear the relays click in, and hitting the power button will cause the relays to click. Other than this, there is no sign of life from this TV. I really would like to find a repair manual or a schematic to aid in troubleshooting. The self-diag trick may be handy if the LED would come on. I'll try it and see what it does.

Your lamp is probably gone

when both the blue light and red light are blinking it means 1 of 3 things. 1. lamp replacement. This often works everytime for the repair. TIP!!! DO NOT USE ANY OTHER LAMPS OTHER THAN JVC AUTHENTIC LAMPS. ANY OTHERS AND YOU RISK DAMAGING YOUR TV FURTHER. 2. the fans are not working properly or need to be replaced. They need to be cleaned every so often and they will stop working from burn-out if not done so. This repair will cost you less than 100 dollars. 3. The ballasts are defective and need to be replaced. The ballasts themselves run about 150 dollars. I tell you I have fixed this TV more times than I care to count, not to mention the number of lamps I have gone through. The guy at the TV repair place now knows me by name when i come to buy lamps. :(

New bulb is just fine.
3 blink shows that lamp cover after replacement of bulb in TV is not fixed properly or not seated well in its position.
Put new bulb and carefully place back lamp cover in its position because lamp cover will press tinny safety switch inside that will send signal to system control of TV that lamp is installed properly.
Turn On TV and get vivid picture of Sony.
Thanks.
