Hi,
These guys are big time fraudsters. This is my case. My Sony LCD TV was not switching on. I called these guys. One of this guy came up and did a quick check. He told the flash memory has gone and it has to be taken to the Service centre. This would charge me about 5 to 6 thousands. I couldn't trust these guys, so I called up the Sony service center. The technician from Sony service center came and did a complete check. He found that there was no power supply to the TV. Finally he found that the three pin used for connecting the TV had issues. There was no problem with the TV at all. I bought a new three pin for 150 Rs.
They are not trust worthy. We shouldn't be giving business to these guys.
Thanks
