TV Repair Questions? Ask a TV Technician for Answers ASAP
I am reviewing your details and will reply shortly.
Do you have the original TV remote?
Can you locate the button labeled "AV"?
Or perhaps "Input", "Source" or "TV/Video"?
Use the Source button to select the Input that you have the Xbox plugged into. Let me know what happens.
Are the batteries good in that remote? Because the Source button is always supposed to change the source.....
That doesn't mean much these days, since the only other cause is a faulty TV (and the set is theoretically too new for that as well). How long have you owned it for?
Okay that doesn't look good.
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up and responds to source normally. Try this procedure up to 2 times, and please let me know what happens.
Unfortunately this indicates a faulty/failed Mainboard in the set and there are no pushbutton fixes for this. We see this issue commonly with Technika and other off- brands and it is why these sets are priced lower than a comparable LG or Samsung I'm afraid. You would need to contact the retailer and start a warranty repair ticket on the set for this issue.
Other than that, I'm sorry for the bad news and wish there were a quick fix.Let me know if you need more help. Also, could you please click a POSITIVE RATING (3-5 stars at the top of the page) and click SUBMIT so that I am credited for working with you today?
You're welcome and best of luck with the set!
