After replacement, raster appears for one minute with horizontal shrink and stretch ( less and full ) about an inch on left and right side .
Checked the damper diode. It's ok.
(Sorry guys. This is a repeat of my previous thread put on two days back (10th June). I have put this question in another place " Ask the community" guessing some experts will reply. But never expected it will be repeated here. Now I don't know how to delete this second post)
Since the replaced transistor blows within a minute, I could not diagnose with voltage measurements. I had to check the components, associated with deflection circuit, in cold condition. All capacitors, resistors and diodes are found in good condition.
When checking the Line driver transformer's (T401) secondary winding, it showed 2 ohms to 33 ohms variably. But it should be @ 2ohms ( constantly ) and not upto 33 ohms. There is a 33 ohms resistor across the winding in the circuit. So the problem is one of the leads of the Line driver is having intermittent contact with the Circuit board.
I have checked with magnifying glass and found one pin of T401 is in loose contact with the PCB. Already at this particular point of the PCB, the original amount of lead ( soldered ) is very low. Hence when I was removing the nearby Horiz. Output Transistor, this particular solder point has developed crack, causing intermittent connection and failure of Horiz. Output Transistor.
After applying adequate lead at that point, and freshly replacing the Horiz. Output Transistor, it is working fine. The link to the image of the crack point is given below.
