I am ne at this post. Hope that I am in the correct place.

Replaced the 3 IC chips STRZ4479, STRW6765 & SRX2039 on power supply board as suggested by the many posts that i searched.
After replacing the IC chips i developed another problem. The power relays (SR80 & SR81) on power supply board are clicking on and off constantly and the yellow light is still blinking as before (3 blinks 1 pause & then again 3 blinks & 1 pause).
Is it possible that one of the new component i replaced is defective?
Presently the only voltage i measure on the power supply board is 5.0vdc on pin 7 of Plug P809.

Before replacing the 3 IC chips i measured the following voltages at power board:

P807B
Pin7 28.7vdc

P809B
Pin7 5.07vdc
Pin9 (ACDETECT) 3.492vdc
Pin12 (Power) 3.039vdc

All other pins measured 0.0 volts on rest of pins.

Please help

You already started a thread about this problem 30 minutes ago. No need to keep starting new threads.

Be patient and someone may eventually provide some suggestions.

From the 3 IC chips which i replaced one of them was defective Q820 (SRX2039). Removed and replaced with existing IC chip and TV was repaired. Ic chips purchased on line from WWW.SUBURBAN-ELECTRONICS.COM. Paid $15.99 for STRZ4479 , $6.95 for STRW6765, $9.95 for SRX2039 plus shipping..

.

Note: The yellow light became steady and TV turned on properly with Blue & Yellow light on solid. .

I had the yellow light blinking 3 times on my Regza. I held the power and the menu buttons down at the same time and the yellow light stopped blinking and the tv works now. I was just about to buy a new tv too.…I guess we'll see if it lasts. I want a new tv, but I don't want to spend the money if I don't have to. Also, I had kind of a faint reddish splotch on the right side of the screen before, and I'm pretty sure it is gone now. I don't know how, but it is.

SBRSHOOTER,
I had a 37LX96 do the same thing last week. I followed your suggestion and the LD blinking stopped and is working normal now. Can you let me if the set you have is still fucrtioning normally after doing what you did? .
