Re: Sony KDL-55EX620 stand-by present, no stand-by light, AC_OFF_DET @.47V
you might want to verify / compare some of the voltages / signals that you had from the other card that didn't work "at all"... to see if anything pops out at you before you send the latest card back.... especially when you get the logo on... hopefully long enough to check some things (hope you have some "hand help").Last edited by budwich; 04-04-2019, 06:18 PM.Comment

Re: Sony KDL-55EX620 stand-by present, no stand-by light, AC_OFF_DET @.47V
where are the points here.. !!! just to sound i am wrong?
simulate PSU to turn on specified line of V. its way we do to be sure PSU working as it should. instate the eeprom script or cpu. in this case MB should be out from this test.
AC_DET never being part at any script in eeprom or or firmware. its hardware.. and any hardware if you simulated will toast other component
PSU Simulating ONLY to replace Script of eeprom or CPU.Comment

Replacement main board installed, no change in status.
TV turned on and displayed the logo the first time then shut off and the red light blinks 10 times. After a 30 second power reset the TV will turn on with no logo displayed then shuts off and the red light blinks 10 times.
Same sad story as before.

Re: Sony KDL-55EX620 stand-by present, no stand-by light, AC_OFF_DET @.47V
And just like a stinking Sony there's almost no info about the 10-blink code. Some places say it doesn't exist, or that it indicates a "watchdog timer" problem, like a processor issue?
How about it? Anyone? Does anyone here have experience with the 10-blink code?? Can anyone tell me where to start???They call me......."threadkiller"Comment

I have got a Sony HCD-BX7700dbi that isn't worth a lot but I'm keen to learn how to repair and would appreciate some help with my train of thought. The protection circuit is kicking in and the standby light is blinking. It goes into protection mode within a second of powering it on.
So far the relay on the power board that enables the main transformer clicks on and then off when powering on the unit. Looking at the schematics, the permanently enabled power rail called 'unreg sub' provides about 13.5VDC. Where the power comes into the main board on connector CN303, there is a diode... -
Hello everyone,
i am trying to repair a Sony KDL-55HX820 led TV which is throwing error code 4 (standby led flashing four times).
I followed the troubleshooting flowchart at page 69, and between pin1 and pin7 of CN6002 i am reading 1.91V so i guess i can rule out the B Board as the culprit.
Before ordering new G* Boards (by the way, should i change both? it is not specified in the manual) i wanted to try and do more advanced troubleshooting since i've read in other threads people resolving their problems on the 46/55 HX 820/823/825 models by replacing the Samsung led... -
Hi everyone, i am a newbie here and i hope i will find the help i need. I have the above mentioned receiver with standby transformer's primary coil damaged. I have searched the net without success to find any tech data about this transformer. I have only the Sony part number1-437-313-11 and TAM Malaysia M0126. I guess i could find replacement for it, but i need to know the secondary coil voltages and VA. It is 220v on the primary. It has 5 pins on the secondary, the outer two are not used and i have 6.5 ohms between pins 2and 4, 3,9 ohms between 2 and 3, and 3,6 ohms between 3 and 4. Can someone...04-14-2023, 03:24 AM -

Hey All,
I have a Sony 65x900f that I purchased cheap because of a no-power issue.
I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.
I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate...
