Question about Sony KP-53HS10 TV
Likely due to age of set the master screen control or the individual screen controls in the set are just set a bit too low---set detects this (called akb) and a simple adjustment may inside the set correct this.
Look or have a tech look first for the master screen and bring it up just slightly until blinking picture stops.

SOURCE: no picture
As soon as the television shuts try these steps.
Pressing on the front panel's ?INPUT? and ?MENU? buttons at the same time, and holding for 5 seconds,
activates the Self Diagnostic Code Mode. The LED flashes denoting a two digit Error Code, or indicating no problem
has occured since the last Initalization.
Please do Note: The front panel buttons must be used, NOT those on the Remote Control.
? The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
? The flashing then pauses for approximately 1/2 second.
? The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
? The Error Code is repeated a total of 5 times.
Example: If the Error Code is ?24?, the LED will flash two times, pause, and then flash four
The Error Code designations indicating a malfunction, or no malfunction, are listed below:
Self Diagnosic Code Description
1 - 2 = no error detected
2 - 1 = X-ray protect (high voltage or beam current)
2 - 2 = Short protect (short protect monitors low voltage supplies)
2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection)
2 - 4 = Vertical protect (usually loss of vertical from the source).
if the tv is under warranty you can get it fixed by the company or you need to contact the local service center to fix the issue .
If you would like to attempt a DIY, you will need a service manual to guide you. You can find one here:
However, be aware that there are voltages inside your TV set that can kill, even if unplugged.
