Toshiba 37LX96 blinking yellow light

[Michael1954]

My Toshiba 37LX96 would not turn on but has yellow blinking light.
It would blink 3 times then a pause and another blink. This cycle repeated over and over.
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.

Did anybody experienced a similar problem

Please help

Re: Toshiba 37LX96 blinking yellow light

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. .

Saw this older post where you had an identical set and wondered if you'd worked out the problem.

Plugged in, I hear one click and then a series of three amber blinks that repeats, no audio, no video, no back lights, nothing. Pushing "Power" button has no effect.

Were you able to resolve this?

Thanks
