Awesome guide! I wasn't aware some TVs don't have a Tcon board - I assumed the circuitboard on the right of the TV was the tcon board. Informative video, thanks.

What causes lost sound in a smart TV

[@DIYwithMichaelBorders]

@@SimonKamau-if6wy Thanks for watching, it can be as simple as a lose connection, dust on connection, or rusted/corroded connection. Worst case scenario, you may need to purchase brand new speakers.

Replaced wifi module wifi signal excellent on both 5g and 2g network will not connect. Bad main board? Please help. Thank you.

[@DIYwithMichaelBorders]

Good morning ☕️ Any update? We recommend unplugging tv and leaving unplugged for 5 minutes. After 5 minutes, plug tv back in and turn on. Next, go to settings and network connection and select your home internet to allow tv to connect. Keep us posted.

[@BillHernke]

It has been unplugged for a couple of days. It finds the network, signal excellent but will not connect to the 2g or 5g. All other devices are working fine.

[@DIYwithMichaelBorders]

Have you determined that the new module is the exact same part number? Is part an aftermarket part?

Hello ,, I have 550 mbps internet speed in home router which I get in my laptop thru lan cable. but the max speed I get in my smart tv is only 240 mbps. I use USB Lan connector connected to USB port of the tv, its better than wifi or ethernet port of the tv..But I wanted to get the max speed in my tv Whats the component in the main board of the smart tv can I get to change so that I get the max speed of 550 mbps in my smart tv. Appreciate your insights..

Ok so my samsung tv no longer powers on and the standby light is no longer lit....is this problem from the power board or main board?

[@DIYwithMichaelBorders]

Thanks for watching, it may be as simple as a friendly cleaning as opposed to either of your boards being faulty. Below is a link to our video showing the cleaning process. kzbin.info/www/bejne/Y4LHgZqVn7Wefbssi=bo-yxjxergfO4xFL If a friendly cleaning doesn’t help, we would start by replacing Power Board.

My Ir sensor on my screen is broke I can’t find the part for the tv aswell😅

[@DIYwithMichaelBorders]

Thanks for watching, have you removed back panel so you could gain access to part? The sensor should have a tiny part-# sticker on it.

[@NateMathis]

i have a 2 year old hisense tv and it shuts off after 60 seconds and then we can turn it back on immidently but it never stay son longer than a minute. I have checked for a timer being set but we dont see one. would this more than likely be the main board?

[@DIYwithMichaelBorders]

Good morning, we are drinking our morning coffee answering any and all questions for the DIY community. Is this solely when using remote or are you tuning tv on by using the TV’s power button? If you’re using remote, it’s likely that it’s the remote causing the issue.

[@desmendETKILLAZ]

@@DIYwithMichaelBorderssame basic issue, verified happens without remote present.

Hi, Was nice explanation. i have problem in my samsumg TV series 7. it was bought in paris and i sent to india. after three days the screen got black and no display is working, Technician said Mother board got damaged and now after changing mother board display still not working. Now he say panel is gone. i hear the sound of TV but can you please say why its not showing the display

[@3fi02]

The hdmi ports and all connectors on that side of the tv stopped working, is it the motherboard that went bad pls ?

[@DIYwithMichaelBorders]

Thanks for watching, it’s likely that a new main board will get your tv running as designed again.

[@3fi02]

@@DIYwithMichaelBorders okay does it have to be the exact same board of the tv model ?

[@DIYwithMichaelBorders]

@@3fi02 Good morning, it’s important to replace it with the exact same part number board. Installing a non-compatible board may lead to overheating wiring and other components.

What if your display zoomed in to much and off centered horizontally? Is it a bad TCon or main board. The TV works fine other than the picture is off centered horizontally and zoomed in.

[@DIYwithMichaelBorders]

Thanks for watching, any update? If this just started happening, you can hopefully reset your picture alignment in your settings. Overscan is what most people call it. Depending on your specific tv, you can reset manually.

[@ctay3559]

@@DIYwithMichaelBorders Yes, It happened about a week ago. I plugged in a mini Keyboard and moments later the issue occurred. I have a Phillips 55PFL5601 TV and have tried to reformat the picture but no luck. I went ahead and ordered a new main board to see if that fixes the issue. Thought of replacing the TCon first but the picture doesn't look bad and its only off centered horizontally.

[@DIYwithMichaelBorders]

@@ctay3559 Thanks for the reply, not a bad idea. Looking forward to hearing back from you. 👍

I have the dreaded vertical lines...replaced my t-con board with zero changes...lines go away within a few minutes and my speakers have strange sounds for a few minutes....I'm thinking main board now.....thoughts? Thanks in advance.

[@DIYwithMichaelBorders]

Thanks for watching, it’s possible. Another cause will be your TV’s ribbon wiring. If at any point during the life of the TV, the ribbon wiring overheated…it will cause your exact symptoms. Keep us posted on your progress. 🧰

I have a Samsung that began turning off by itself and then on again. The time between on and off gradually increased and the the time that it stayed on decreased to only a second or so. I've replace the power and the main boards. When plugged in now the red ir light come on and blinks but no response from remote or manual inputs. Any help?

[@DIYwithMichaelBorders]

Thanks for watching & welcome to the DIY Raptor Club. The most common cause is an internal timer set. This is unfortunately & accidentally turned on during a replacement or change of your router, internet provider, or even a power outage. Timer can be deactivated within the settings. Keep us posted. 😎👍

It is the same OEM part number. When I search for available networks, it see's the networks (2g and 5g) says signal strength is excellent but will not connect.
