Sony FD Trinitron WEGA KD-27FS170 TV red light blinks 4 times and I have already changed the IC561, and It still turn's off and blinks 4 times. I have reset the tv error codes.
this is acacpc I don't know how to use an oscilloscope, so I don't know how to test the 13 volts but I did change the IC702 and am still having the same problem. you gave me this info but not sure how to test anything else.
4. Error code of 4 blinks . Dead set press power button you hear the relay and you see red led flash 3 times and stops? Has no HV or other action. Tech removed the back as no 200 volt supply, did unplug CN706 and now has 200volts. Tech did remove the IC702 and same it comes up so needs this IC.this is acacpc

This typically means you have a bad capacitor, you can inspect for any swollen or bulging capacitors however unless familiar with desoldering boards best leave it to a repair technician.
Yes, there's a posibility that IC561 is partially faulty but on the symptoms you've described, I would advice you to replaced first C539(470uf/25V) and C561 (47uf). I've suspected that these filter electrolytic capacitor is already leaky or dried up...
When a TV hasn't digital tuner, it's necessary to add it a digital to analog channels converter box, but your TV already has digital tuner, you can switch between digital and analog tuning by pressing the digital/analog botton on the remote control.
