Yet Another Track Cut Saves One More LED TV, SANSUI MODEL SJX32HB02CTF
This TV belongs to a colleague who works in the accounts section of my hospital. It was brought to me with the complaint that there was no display. The display seemed to have gone off when they switched on the TV on a morning. I checked and found that the back light was ok and there was no display. I opened the TV and did a thorough cleaning inside. Noticed that the circuit and panel were more or less same like the Ego LED TV that I repaired earlier in the day.
So, straightaway I went for checking the voltages to the Scaler Board and outputs of the control IC. Exactly the same way how the EGO TV (covered in separate article) behaved, this IC went to protection mode after a flash of outputs. So, I knew that I had another panel short case.
So, I took my knife and cut the CKV tracks on the left side assuming that in this TV also it could be the problem. But for my disappointment, the problem was on the right side. Voltages got released from the booster IC only after I cut the tracks on the right side.
So, I rejoined the left side. The display was ok and I ran the TV for several hours before closing the back cover.
Though the work was completed satisfactorily and got collected, the thrill was not there as mentioned by me in the other article.
I do not like to do these cutting jobs! But there was no other go!
