The tv was working fine yesterday. but we we tried to turn it on nothing hapened. What can be the problem

Change you hdmi connector.

Nothing to worry, You change to AV mode to TV mode and wise verse,
If nothing happen then call the service center, It only two months old.

Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

Have the battery load tested. Just because its 2yrs old, does not mean good.

call ins. comp.

Dear,

can u do repairing or have you ever troubleshoot the issue by yourself.
if yes, then open the cover and check the continuety of the power cable because it can be the damage cable. if all of then check the fuse inside the circuit board where the main power cord goes. the must be a glass fuse. Check is it in working condition means having continuty too.
if this component is ok then u have to check the other circuitry.

regards,

Sound like the guage cluster has went out. You will have to replace the whole dash cluster, Check with junk yard to save on money.

Check your battery connections make sure they are tight. If they are tight, then you have a bad battery or alternator.

I checked the mains switch (found on the top of the tv) and when I switched it back abd forth the tv started up and has since been fine.

Hi,

Maybe your logic-board is a little stressed.
If your TV doesn't response on your remote control, the only way to switch off is to unplug it.

After one minut you can plug it in and give it a try, no problem.
If it still doesn't work, you have to visit your dealer.

Kind regards,
Gerard
