good morning colleagues I have received this previously mentioned Sony TV model with BA6 chassis, initially, with the failure to give video just listening to the sound. When turning on this TV at first the video appeared but it vanished in a few seconds leaving a background like gray and on its right side of the screen some dark lines that some were reduced and others not so much as wanting to try to close the horizontal deflection. after this point, perform a visual inspection as a first step, checking that the filament was on, which is what it was like ... then check that the video amplifier IC had at least its supply voltage which was present as well as the voltages of the G2 Seeing that there was no problem on the TRC cannon card, I proceed to perform the check in the ABL section where in its path I find the R584 18K resistor fully open and here I proceed to replace it but with a resistance that is not precision but that has the same ohmic value. Once set I proceed to turn on the TV and at that moment he gave me video and everything seemed to stabilize, however after the ignition it remained for at least 10 seconds and during that time it was heard at the same time, with the TV on, a high voltage leak that I could not observe to such an extent that I ended up turning off the TV flatly without any chance of turning it on again since it did not obey so much on the front power button as on its remote control. After this new problem, check the THS (2SD2645) to determine if it was affected and so it was, since when measuring between base and emitter it emits continuity beep marking 90 ohm, but the measurement between emitter collector did not show damage, managing to measure its internal damper diode, which I finish by removing it from the board and proceed to check that the source delivers its required + B (135.2 volts read with a 60 W focus as a load). From this point I begin to suspect that the flay back may have problems, however I also checked the yoke and at this point the measurement of the horizontal coil is 1.2 ohm which I do not know if that is normal, the measurement of the coil Vertical is 8.2 ohm. Now when trying to measure the frequency of the horizontal this gives me a value of 16.14 KHZ which I think is very high considering that it has the THS removed from the plate and knowing in advance that it is to be approx. 15.7KHZ I would like to have the support of colleagues to know their opinion and thus know what measures to take on this issue since if I place another horizontal I run the risk of burning it, in advance thank you very much.
