Sony Wega FD Triniton KD27FS170 Does not...

The most common fault with this model is the flyback transformer assembly is defective. Along with this, the horizontal output transistor may have also failed. In some cases this failure occurs because there is a drive problem coming from the horizontal scan driver circuit that is ahead of the horizontal output circuits. There may also be some support components that triggered the fault in the first place and would also be required to be replaced. When there is this type of failure, it is possible that the power supply may also need some service.

On more rare occasions, there may be a simple failure from the main power supply buss, or a failure in some other circuit that is putting the power supply in to protect mode.

An experienced TV tech who knows your model of Sony set can troubleshoot it and determine the exact failures. He can then give you an estimate.

This model of CRT set was considered to be an excellent TV set. Unfortunately when the full digital service is established as the standard, and the analog service is discontinued, you will require a digital to analog conversion box for this set to work with TV stations. Some cable TV and satellite TV companies will be supplying the analog signal in their standard package.
