My 2018 QLED Q7 TV entered the evil reboot loop forever after just 2 years and 4 months of normal usage. It is the first TV failed in my life time and it is the most expensive too. Very low quality and short warranty !!!
I have hard time to find a OneConnect replacement box on eBay. On my OneConnect box, it has many numbers.
Center label: BN96-46074K (75Q7F)
Upper left label: BN44-00935B
TV: QN75Q7FN (or QN75Q7FNAFX)
Year: Nov 2018
Do I need to find a box with exact same number for all 3 above ? Or do I just need to match for the model number ?
Thanks for direction.
In normal time, I would visit the repair shop. Recently, the covid19 infection rate is raising in my town. Jumping from 200+ to 1500+ each day. Many people carry the covid19 virus with no symptom at all. I will wait for the whole city to finish the 1st dose of vaccine in next 4 months, then I shall visit the repair shop. At my age, it is better to be safer.
Some people said the capacitors and transistors on the power module easily fail on the Samsung TV product. Many people had this issue over many years. Samsung should recall and repair these TV for free. I see a few class actions on this issue. I will order some electronic parts online and try my luck.
Some reviews said the OneConnect box can be replaced with new model to get latest HDMI version in the future. This is why I spent so much on this TV. Last week, I asked the Samsung rep at Best Buy, he denied it now. It seems each OneConnect model is only good for certain TV models. Very proprietary and not open at all. It is not a good investment to spend so much for a low quality Samsung TV product... A very expensive $4300 lesson.... Next time I will buy the VISIO, they have 3 years warranty from my local Costco. Beautiful picture for 1/3 the cost.
