I just replace the new bulb for my tv. suddenly the bulb cannot light up. the front tv have red blinking
Make sure the lamp door switch is gettng closed, and the door pin is not obstructed by something. Also possible a bad generic new bulb.

3 times means Lamp and 6 means you have lost a voltage. You may have a thermal fuse blown.
This set has a common trouble with overheating caused by the drum fan located on top of the lamp housing clogged up with dust. When the lamp is getting old it runs hotter and that combined with the fan being clogged the thermal fuse blows. You must replace the lamp and thermal fuse. You must also clean out or replace the lamp fan. This drum type fan should be cleaned out every year or two depending on the environment.

5 blinks code shows problem with Lamp Drive circuit (ballast supply) and / or Lamp itself.
How old is this TV and have you replaced lamp before?

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.

Thats usually caused by a regulator having failed.or could also be a wire cable not connected correctly. Troubleshooting the power supply will verify if the +17V line is missing

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!
