So finally after 5 months and 1 day of raising the complaint, the issue got resolved today.
There was no issue with the OLED panel, but it was wrongly diagnosed as a panel issue by the LG technicians. The actual issue was that there is some rust/fungus developed on connector cable.
The cable was replaced and the TV is working fine now, without any issues.
On Feb 19th , I had posted the possibility of wrong diagnose by LG technician
here. But these technicians are very incompetent, and even though I raised this to technicians and their managers they were ready to listen.
Below are the chain of events that had happened as per my understanding.
June 2022: TV didn't turn on due to rust on connector. Technician wrongly diagnosed it as panel issue, and replaced panel under extended warranty. TV still didn't turn on as cable was not cleaned.
TV was then carried to service center for "more" analysis, and somehow when reconnecting few times the cable got a good connection and started working.
Technician wrongly thought that TV worked due to Pixel refresh completion and returned the TV with new(replaced) panel.
Dec 2022: I had not turned the TV ON for a week, as I was out of town. It was raining in Chennai, so the moisture could have again caused the rust or fungus to grow.
The technician again did the same mistake of flagging faulty panel.
May 2023: Panel was replaced, but the tv still didn't turn on. As I was paying from my pocket this time, I was adamant that I oversee their repair job.
I didn't allow them to carry the TV to their service center, and they had to a thorough step by step check and diagnose the exact issue, and found that the cable could be the culprit.
Replaced the rusted cable and it worked. Since my older panel was not faulty, technician removed the new panel and connected my older panel (anyway it was used for only 30 hours earlier) and it worked fine.
The newer panel was returned to LG
Expense
First Price Quoted by LG - rs. 1,29,318
Site Visit in Dec
Site visit charge in Dec = rs.472
Repair cost in May
Spare part
= Rs.314
Labour = Rs.1859
---------------------------
Rs.2173
Total Damage : Rs.2173+rs.472
= Rs. 2,645 + a lot of mental stress.
Loss of LG: The panel that they replaced in June 2022 would not have been faulty. They wasted a good panel.
My Loss:
1) 5 months without tv
2) Lot of time for back and forth communication. Irritation for just loosing out of warranty by 7 days and being asked to pay 67k for replacement. Lot of dilemma whether to repair OLED or go for a cheaper new TV.
3) Lost Some good relation with LG sellers. As I had to use pressure tactics to push them to get better offer for panel replacement.
4) Chance to get a panel replacement under goodwill. I think LG normally provides only 1 panel replacement and I already got it in last June. Probably they will not offer anything next time.
5) Rs.2654/- , if the issue was correctly diagnosed in June 2022, the cable should have been replaced at that time under extended warranty.
Anyway it is finally settled. Happy to have my TV back.
Till yesterday my OLED was showing only absolute black , today it is showing absolute black along with other stunning colors
.
Thanks to all fellow members and mods for your help and guidance.
