Sony tech: I need your help! KV36FS320 dead
This Sony KV36FS320 will not power up, just 9 flashes of the standby/timer LED,
unless I press the power button while energizing the power relay manually, ie Q608 base drive for 1 second. Then the set will run and -everything- works until I turn it off again. All standby supplies are working, zero cross pulses are there, and the M board has been swapped. That's where the power-on pulse is supposed to originate but there is no pulse at power up. I really need your help with this one. Thanks in advance! Ray Carlsen, A/V engineering, University of Washington, Seattle Ray -- My return addy is spamblocked. To reply, remove the zeroes. |
