Beware Of Panel Broken Cases When No Display TVs are Taken Up For Service
This Impex LED TV Model Smart32 was brought to me with the complaint that there was no display. The customer was known to me as he had brought CRT TV for servicing long back. After opening and cleaning the inside, when I switched on, I noticed that the Voltage outputs and the voltages at the Scaler Board were ok.
When I checked the voltage for the backlight it was showing full, which indicated that the back-light was defective. I checked the backlight with my LED Tester also. So, dismantled the panel and took out the back lights. Went to market and bought exact replacements.
After fixing the backlight and placing the panel back, when TV was switched on, I was shocked to see that the panel was cracked on the left side. I was sure it could never have happened from my side, as I was extremely sure of handling it very safe.
On close observation, I could see traces of an impact in the middle and guessed that it would have caused only if some children had played ball inside the house and happened to hit the panel. This was such a thin panel that I had to be extremely careful in removing it and placing it on my bed. I called the customer and told that TV was back to working, but I had noticed damage to the panel for reasons as assumed by me. The customer agreed that his children were playing football inside the room where the TV was kept, which was a big relief to me. So, friends, beware of such possibilities. In this case, the customer agreed. But according to my techie friends, the customers sometimes deliberately bring such sets and accuse technicians for getting a free replacement.
So, there is a risk involved whenever we get sets with display off. Normally, like in this case, when I see customer holding the TV pressing their fingers on the panel, I warn them that any hard press on the panel would crack it and can be viewed only when back light gets on. That statement, rather an advance bail, might help us face such situations.
Though I was a bit hesitant to add satisfaction to the collection, it pacified me that I had done my work well. So, operation was successful, though patient died! (LOL) Customer collected the TV and paid my charges.
Though I politely declined to take it, he insisted on paying and was found apologetic. Well, such good customers are also there!
