Servicing Philips CTV
This colour TV belonged to my son’s in-laws. During one of my visits, when they told me they had a problem with this TV, I removed its board and brought it home for rectification. The TV was dead, earlier to which, the remote was not working for quite some time.
After cleaning the board up thoroughly, on visual inspection I found that one 1000uF/25V capacitor was bulgy. Checked and found out that ESR of two more capacitors were out.
Found very dark burnt marks under the Rectifier diodes on the secondary side.
Replaced these three capacitors and also replaced the strained diodes after scraping the board clean to the extent possible. Replaced the remote sensor, as all other associated components were found ok.
The board was lying with me for a few weeks, as I wanted to club my visit to their place along with any other needs to visit that area. Recently, I had some function to attend in their town and went to their house in the evening and fixed the board, and switched on.
The TV worked very well. Since the screen voltage adjustment in Philips is very critical, I had taken precautions not to disturb the control while cleaning and handling the board.
Another job added to my satisfaction list, without any complications and confusions!
