My problem with my Sony VGN-SZ330P is the fan, it producing some loud noises, sounds like its grinding something

There are a few possible reasons why your car might be producing a very loud, continuous sound that can only be stopped by disconnecting the battery. Some potential causes include:
1. A faulty starter motor: If the starter motor is faulty, it can cause a loud grinding or buzzing noise when attempting to start the car.
2. A malfunctioning alternator: If the alternator is not functioning properly, it can cause a loud whining or grinding noise.
3. A stuck fan belt: If the fan belt is stuck or has become worn and is slipping, it can cause a loud squealing noise.
4. A stuck horn: If the horn is stuck, it can cause a loud, continuous honking sound.
To determine the cause of the loud noise, it is recommended to have the car checked by a professional mechanic. They will be able to diagnose the issue and suggest the appropriate repairs. In the meantime, to stop the noise, you can try disconnecting the battery as a temporary solution. However, it is important to identify and fix the root cause of the issue to avoid further damage to the car.

You can download the video and device drivers from the Sony WEB site.

This means that the micro ball-bearings are on their way out if the bearing race smashes then the fan will stop I suggest sourcing a brand new fan and fitting it yourself you might need a star drive look at the profile head of the screws.

Make sure that both the mains supply and battery are removed, the fan will be a simple push to clip connection with only 2 wires.

Hi kufreudokang,

Don't worry thats not a big problem, you have a lot of dust deposited on the fan, thats why its making so noise.
Once you clean it, your fan will make very less noise, the way it did before.

If you are sure it is the fan then you should get it replaced otherwise you will have issues with overheating.Sz model is quite a big job to replace i suggest you take it to an authorised sony repairer and get a quote.

The sony VGN-S460 seems to have an inherent problem with their cpu fans. It is apparent that the fan uses a ball bearing system which over time becomes worn and causes the grinding sound.

The only solution is to replace the entire fan assembly as they are inseparable.

take it to an expert... the fan is faulty

That is definitely a problem from the fan. What you can do is to call sony and check if they still cover Fan replacement for this specific mode.

Yes, its fan noise and you need to replace noisy fan.
Let me know exact model of your Sony TV and need to know what fan is producing noise to provide you part number and parts shop info to buy that fan.
