Hi,
I have got a new TCL 65P8E installed at my home yesterday, replacing a TCL L43P2US.
Installation went fine and the picture quality is great for my requirements. But later at night when I touched the panel to take out a sticker, I got a mild electric shock along with a buzz/crackling. Immediately I checked the metal parts (screws, connectors, metal part of the bezel) of the TV with a line tester and a multimeter. The line tested glows faintly and the multimeter reads 96 V AC. I did not get the electric shock again when i touched the plastic or metal parts of the TV, so I suspect the buzzing and the shock was due to electrostatic build up due to the stray voltage seen on the metal parts.
Since then I have read few posts on similar issue and the general theme of the responses is to check the 'earthing' of the building. Even when I called Reliance Digital (from where i purchased the TV), they also immediately tried to push back saying it must be an 'earthing' problem at my house. I have two questions at this point.
1) How can the problem of "earthing" of the building cause this problem when the TV itself has only a 2-pin plug. (I think most TVs have only 2-pin)
2) Why don't the TVs ship with a 3-pin plug? (I've read about the double-insulation, but with exposed metal connectors, TVs seem to be good candidates for 3-pin plugs)
I have requested Reliance Digital to send a technician to check and confirm, so waiting to see how it goes.
Meanwhile I have done the following things to isolate the issue:
0) Removed all external connections from the TV - (Firestick HDMI, Firestick USB power, 3.5 mm connection to Amp, LAN connection)
1) Check Phase and Neutral lines in the socket- Result: Only Phase glows with the line tester. Multimeter reads 230 V AC
2) Check voltage between Neutral and Ground lines in the socket - Result: 0 V AC
3) Reverse the plug of the TV - Result: No change. Metal parts still shows 96 V AC
4) Remove the stabilizer, power strip from the power chain - Result: No change.
5) Remove the inverter of the building and connect to direct power supply - Result: No change.
6) Connected a wire from metal part of TV to Ground in the socket - Result: 0 V AC
Can someone please help me to answer few questions before I push Reliance Digital/ TCL for help.
1) Did someone else face such problem? What was the solution?
2) Is this expected/a common occurrence? - the voltage on the metal parts and the electrostatic build-up and shock?
3) Is there any way to conclusively narrow down the issue to a faulty TV and get it replaced?
Thanks for reading and TIA for the replies.
