The television suddenly shut off (while we were watching something). Loss of picture and sound. We noticed the stand-by light blinking (2 short blinks, pause, 2 short blinks.. etc. We waited for a while, then turned it on again and I heard TV making a 'clicking' noise like it was turning on and then off

The set MAY have the self check feature.

If the set is plugged in and you turn it on and a few seconds later the power light goes off:

On front of set press and hold both the menu and input (device on some) buttons at same time for at least 5 seconds and release both.

Power light should then blink a two digit error code like 2 blinks, 2 blinks a pause and repeat the error for a total of 5 times.

If you get an error code let me know what it is.

THE click is the relay on the power board coming on and then going off---red power light should blink a error code---when set shuts off (second click) watch the power light and count the blinks.


Let me know what you find.

SD TECH

line o/p transformer &transistors are gone .. any service person can replace them

if complete service manual will help,you can download it from my ftp sight request at [email protected] its has 133 pages and 15mb big.has alot of step by step info.

This sound like you are having problems with the power supply board. Since you are getting a momentary picture and sound the fuses are good but TVs today have "shorts" and "overvoltage" circuitry build in that will shut it down on errors. Someone knowledgeable in electronics will have to isolate the exact cause.

Good Day, checho3435;

Look for fluid on the PCB's or check these items:

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 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). Good Luck, big IRISH>

How many times does it blink. It should be blinking a repeating code if its in protective shutdown mode. A continuos blinking with no pauses means.
No reply from the jungle IC(data bus is busy, shorted to ground or held
high), IK video path is defective.

Something shorted and shut your set down. Most likely the high voltage transformer shorted which also shorted the horizontal output transistor. Stargazer

I hve worked on a number of these units , your description is typical of a shorted blue picture tube. The protection circuits in the tv detect that there is a problem thus shutting the unit down to prevent further damage. Sony had a bad run of picture tubes in this series. The replacement cost of the tube is about $250 plus labor. My estimate would be for the repair about $400-500 depending on where you live and how honest your local technican is. I will caution you however, that you could replace this tube and the red or green could go. These would not be covered by the technicians warranty. When these sets are working, they have a superb picture and it is easy to get lured into fixing them. Scrivitron
