Facing TV Problems? Ask a TV Technician.
Hello, My name is ***** ***** I'll be assisting you. I'm sorry you're having problems. Please note it can take me a few minutes between replies, so please be patient.
Also: If you receive a phone call offer, that is not sent by me - it is sent by the site without my knowledge. I am not available by phone, so please keep in mind I will be engaging you on this page.
Can you get me the full model number off of the back of the Sharp?
Also, roughly how old is the TV?
I'm not sure if you're having problems replying? Please don't try to reply to the e-mail the site sends you. Instead use the link to get to the site page and reply here.
Thanks for the reply. Offhand when this issue occurs after a storm, it indicates that the Mainboard of the TV has suffered damage, and this generally requires this part be replaced. There are no settings/adjustments, etc. since none of them can be accessed when the issue is occurring anyhow. So, that said, you will likely need to replace the Mainboard to fix this issue.
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 normally. Try this procedure up to 2 times, and please let me know what happens.
Are you still having the same problem?
Okay, I can understand that. If the issue persists then the Mainboard in the set would indeed need to be replaced, which is part number Sharp DKEYMG460FM01 for this set. It's showing as currently out of stock, but you can put yourself on the waiting list at the site below if you want to repair the set yourself:
Alright sounds good.
Sorry to hear that, and yes it would indicate the Main has failed (this is the processor for all of the pushbutton and remote commands in the set).
Let me know if you need further help. Also, please do click a 3-5 STAR rating for my efforts before you go. That is how I am credited for my efforts by the site.
