Hi
          It is a problem of high voltage transformer.Better change it.
                             or 
High voltage supply is what give the high voltage power, consisting of components. You ask for this or do you mean you need the High Voltage Transformer or another Item on the board? Do not understand!!
                             or
    Test the Switching Transformer
SMPS switching transformers, like flyback
transformers, are high Q transformers.
They are responsible for transferring a
large amount of energy in a short period
of time. A single turn short will shut down
the SMPS. Be sure to use the patented
Sencore ringing test to test any suspect
switching transformer.
                   or

Four blinks actually a code that indicates power failure. There are several possibilities; Either power supply's component malfunctioning (e.g. dried/blown capacitor). Within the main circuit a failed component might be taking over current. Best diagnostic can be done by a qualified hands on technician by isolating the circuits and testing individually. If you are a tech please let me know so I can give you some instructions.

I have a sony wega trinitron, when the tv is turned on, (no visual, or sound) the red stand by light blinks 7 times, and you hear the tv click off? Please help


Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.

Try the 60 seconds unplugging of wall plug in your outlet. Or check your line if this have surge protector. Temporary plug your unit to wall outlet directly. Just check if it still within voltage operating range.

Cannot power up my Sony Trinitron KV-34HS510.


makes a noise
This doesn't tell us much; is it a click or a sharp snapping sound?
The first can be a relay turning on, the second is most likely related to a high voltage discharging.
If it is a relay, then the set could be trying to protect itself from an overload or the power supply has failed; the blinking ON LED is pointing toward that.
If it is a high voltage discharge (you may be able to see it through the vents in the rear housing) then it is possible that an accumulation of dust and household airborne contaminents has created a path that can be removed with some targeted cleaning.

Sony KV-32FS120 blinks 4 times


good day.
Have you tried first resoldering the terminals in the circuitry?
Also, try to check for the ABL supply near the flyback. Watch out for the small voltage zener diodes.


response is highly appreciated.

Kv24fs120 dead set with two led blinks


Two-blinks of the "Diagnostic STANDBY/TIMER LED" indicates one of two things:

1) Horizontal Output (Q502) in shorted on the A-board.

or

2) IC702 is shorted (CB board)

Two-blinks of the diagnostic red LED is a " B+ Overcurrent" problem.
The red LED will blink 2-times, stay off for 3 seconds, then blink 2-times. The cycle repeats.

The circuit board is quite delicate. One should not attempt repairs (unless one has high quality vacuum desoldering equipment such as a PACE desoldering unit).
