Tv is in stanby mode. when i turn on power it seems like it wants to start but nothing comes up on screen. stanby light is blinking

The problem is in the main board of the tv, it is either a power supply issue or a high voltage problem. In order to isolate you will need a tv tech to check the set out and cost involved.

Sony Wega FD Triniton KD27FS170 Does not Start-

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.

No picture

This can be a scan amplifier failure, failure in the high side of the main power supply, the picture tube may no longer be having emission, or the heater supply to the picture tube may not be working. There are many parts inside the set that can cause failures.

You will have to take the set in for proper shop service by an experienced TV tech.

No sound or picture just blinking green light

That sounds like a power supply Issue, Unless you have the full service INfo and proper equipment its best to call a repair tech for your model as an isolation transformer is needed to saefly diagnose the power supplies.

This is an indication in most cases that the flyback and horizontal output transistor are failed. Along with that the power supply may need service.

Take the TV to a service center to have it repaired by an experienced TV service tech.

I can tell you that this type of repair will not be low in cost.

Sony Trinitron Power Surge 5 Blinks

once you have diagnosed the problem, the following link is to all parts for your tv stocked at partstore. they generally have better prices than the dealers and repair shops.
KV-36fs13 parts

you can try the dead-tv kit from fixyourowntv if you have some basic experience with soldering and circuit repair.

Five blinks means, "IK (AKB)" (white balance). The probable causes listed by Sony are as follows:
1) Video OUT (IC561) is faulty (A board)
2) IC355 is faulty (A board)
3) Screen (G2) is improperly adjusted.

not sure what the 13 blinks are for.

hope this helps,

Your missing a voltage is all. Its in the power supply or the hi voltage supply. If your a tech then you know of the hi voltage dangers in this set even when its turned off!! if you wanna trouble shoot this correctly go to Howard W Sams and get a service manual, Its available for 55.00 And see whats going on in the set. If you take the set in the servicer will need to purchace or already have this manual . Good Luck
