The 4th PCB also gone dead today...it lasts for 2½ day.
I got few learning from my tv issue over the year
1. Dont buy high budget fancy tv. Its repair cost is also high.
2. The extended warrenty service available is in market is hit and miss like service. Go warrenty/Acko/jeeves all providing refurbished panel/PCB to customer and its depend on your luck how it will gonna be. For me its lasting 2 days to 9month.
3. Branded tv like Samsung/Sony/LG and other non branded Chinese tv like Acer/Vu/Hisense/thosiba/Mi/ifalcon all should be used with Voltage stabilizer especiialy samsung tv.
I already and again Registered a compalint with jeeves And I know again they will replace the PCB which may last max 1 day to 30 days and then I have to register complain and so on until my warrenty service got expired.
