Hello My TCL 75 P8M the LED powerligbt is on. However when I press power up on the remote. The LCD does flash slightly and goes blank. Which board do you think I need replaced? MAINBOARD or POWERBOARD? Thanks!

I replaced both boards main and power supply and it had the red standby light but when I try to power it on it shows a black screen then powers right back off any suggestions?

[@DIYwithMichaelBorders]

Good morning, just poured a cup of coffee and am sitting down to answer any and all questions for the DIY community. Since you have replaced both Main and Power boards, the next thing is your TCON Board. However, not all TV’s have that little green TCON Board…our doesn’t. The TV in this video doesn’t have a TCON Board. If thats the case for you, we recommend opening TV back up and double checking all electrical connections are properly secured and not damaged, nor showing any signs of overheating/burned discoloration on wires or board. If all looks good, next part to replace is your IR sensor. Below is a helpful DIY guide on how to do that. kzbin.info/www/bejne/eWjMi5d5qdydebssi=GVMCYJKQmIuImWvm Also, below is a link to our TV repair PlayList.

[@DumbKoolz]

@@DIYwithMichaelBorders okay I’m going to get a IR sensor the tv attempts to power up with a black screen then goes right back off if it was the LED would it still attempt to start up?

[@DIYwithMichaelBorders]

@@DumbKoolz Awesome. It’s possible, can’t rule it out…👍

[@user-of5gb6wi6u]

Hi there same issue! I purchased this TVs year ago and I can’t remember the exact model name but it’s a 65” Hisense. It has been working perfectly fine for the time being but recently just 3 days ago upon watching tv the screen got darker, I turned off the tv and turned it back on and it just got darker and darker. Now I can’t see anything and all I hear is the tv. Day 3 now, it won’t turn on at all, anytime I use the remote to turn it on the red sensor light on the tv starts blinking. I already tried all the suggestion’s that I searched on Google. Any help?? I really don’t want buy another Tv, this compared to my last Samsung was great, and i already need one for my bedroom so that would make 2 new TV’s that I need since I just moved it’s just more unnecessary expenses and i don’t drive so it’ll be real impossible to get a tech over but I have no problem doing it myself I’m pretty confident but I just don’t know what the actual issue is

[@DIYwithMichaelBorders]

Thanks for watching, that’s no fun. It’s possible that the power board or main board is faulty. It’s likely that the power board feeds power to the panel and replacing that will get your tv back up and running properly. If the power board doesn’t fix issue, main board would be next.

[@user-of5gb6wi6u]

⁠@@DIYwithMichaelBordersawesome I appreciate the help really! It helped a lot! And as for the power board they’ve said about $300-$450 just to fix and I don’t trust these second hand places because they’ll just lie and say something else is “wrong” so where would you suggest to get a 75” Hisense back panel/Backlight?

[@prospectboy]

Hello! My ONN tv wouldnt turn on, but the power light where the power button is located would continue to blink. I had Geek Squad look at it, and they said it was the power board. I purchased a power board and replaced it, but its still doing the same thing. Any ideas on what could be the issue, or could it be the main board that is the problem. Thanks!

[@DIYwithMichaelBorders]

Good morning, just poured a cup of coffee and am sitting down to answer any and all questions for the DIY community. You may have an IR sensor in its early stages of failure and acting sporadically.

[@nyahwalker7873]

Do you need to ground yourself before touching the power supply board?

[@BushyBrow_Sensei]

If my tv is coming on dim for a moment then shutting back off, is this my problem? Or is it something else?

[@samanthal7062]

Omg this is my problem too!!

[@ckalo7]

Same here, it seems like the yellowish power circuit got messed up… I think I’ll try to follow the video and replace mine.

[@BushyBrow_Sensei]

@@samanthal7062 yeah apparently its the power source, you can search power supply board and your tvs serial number, and you can find the correct power supply on amazon.

[@Exidose]

I'm having this issue! Did you find out??

My tv comes in has sound but no picture. How do I fix this? I hit the reset button, un plugged then plugged it in and still nothing. Help

[@DIYwithMichaelBorders]

Thanks for watching, any update. Kinda sounds like an electrical connection inside the TV is loose. Removing back panel to gain access to the internal portion of the TV to inspect your connections might be the next step .

[@MayowaAdeniyi-f6d]

The tv will work for 30 minutes and off by itself starting blinking the red light 3 times continuosly

[@DIYwithMichaelBorders]

@@MayowaAdeniyi-f6d Thanks for watching, any update? It’s likely that you have a part internally that’s in its early stages of failure and acting sporadically. Replacing your Power Board is a good start.

[@calvinconner8460]

What is the part number

[@JTScott1988]

Differs per tv…. Look on back of ur tv… it should have the model number. Use model number and tv brand name to search up the part.

[@DrStew]

I had the same question about how to order... I enjoyed your video and subscribed. Now I could use a video that is easy and quick fo changing backlighting.
