Sounds like the ballast is whats causing the issue the leads are probably charred at where the leads attach to the lamp connection. Pretty common problem when you hear that sound. I would check the ballast and if you need one you can get one from www.tvcircuitboards.com

which fan, the unit has at least two of them. You getting a fan error or what? The Sony sets do have a error buffer you can try to call up.

Since you are here you have a computer and Google?Google the model number with error code, or problems, or what ever issue you have to see what is out there.The Sony website also has this and any authorized repair shop can access their tech database with model and issues to model.

I have just bought a second hand Sony 50 inch Projection & the owner from new (paid 1200 Quid) assures me he has never replaced the bulb in 6 years.

Best left to a professional, you have to remove the front screen and clean mirror, plus it might be the lamp or the optical block that is having an issue. the SXRD series has been know for this.

Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

If the standby light is flashing 3 times. (your post says 3 times 7) I was unclear... A error code of 3 blinks inidicate that the door covering the lamp is not secure oer the lamp is not secure. Make sure the lamp door is seculy screwed down. ussally the door push a little switch closed. If this doesnt work the next thing to try is to remove the bulb carefully(dont touch the lens) and replace it making sure the bulb is in place securely. let me know if i can help any further

• Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen A2 slightly.
  

you need to push the new lamp all way in and down a little this set has a microswitch at the end of the lamp.
