Can anyone in the Concord/Kannapolis/Salisbury area recommend (from experience) a TV repair shop. It appears lightning got the HDMI ports on our 40" Samsung. I tried all the Internet recommended cures... none work so I assume it is fried. Otherwise TV works fine. No Charlotte area shops please... dread the idea of driving there. ThanX!!! :)
 
Dying breed. I used to do consumer electronics repair. You're easily looking at $150 in repair, and you can replace it for $250 with a Hisense or TCL brand Roku TV. I've got experience with both, both are fine TVs for the money. If that Sammy is over 3 years old, I'd consider it replaceable. If you find someone who can fix it for less, you got lucky.
 
I had the same thing happen to a Vizio tv. I found a guy that sold repaired circuit boards on eBay and replaced it myself. Has worked since then. If you want I can see if I can find the guys name.

I pulled the back off the TV and searched the part number of the board that has the HDMIs on it. From all info I could find it is the main board and if the HDMIs are bad it is the board needed to fix it. eBay price is about $65. I have a VGA to HDMI adapter that I use to pipe movies from the computer to the TV. My son is taking the adapter and all wiring to our church this evening to test it on a known good TV just to be sure it all works as it should. If everything tests OK I believe I will gamble on the eBay card and attempt fixing it myself. Appreciate the replies! :beer::beer::beer:
 
^^^UPDATE: My son tried my converter at the church... apparently it got fried too. So, he used a converter belonging to the church, hooked it up to his laptop and verified that all worked OK on one of church's TVs. Then, brought the same stuff home and hooked to my TV. Result... my HDMIs are obviously fried. I just ordered a new main board card from eBay. SURE HOPE IT WORKS! I'll post results after I get the new card.
 
I think this thread jinxed me. Read it yesterday and thought 'just buy a new one'...woke up to get my daily dose of ESPN this morning, 60" LG had sound, no picture...awesome.

Sounds like backlight drivers or board.


There are tons of YouTube videos of how to troubleshoot and fix the newer tvs.

Thanks. I'm an electrical dunce...but figured I'd do a little research. When I did turn the tv off, the pic would flash on the screen right before it actually shut down. TV is only about 3 years old.

Turn the tv on, turn lights off in room, and shine bright light at screen.

If you see the picture then everything is working other than back lighting.
 
UPDATE: Today I received the main board I ordered off eBay. I am VERY HAPPY to say IT WORKS!!! My TV is fixed, and it cost me $65.99 vs the $200 estimate I got from a local TV shop. Any TV repairmen out there, have no fear!!... I am NOT going into the TV repair business! :lol:

NOTE: From now on, we will pull the HDMI cable when we're not using it. :huggy:

UPDATE: Before I trashed this tv I wanted to at least pull the back off...pull the back off about two weeks ago...bam, picture comes back. Literally didn't do anything but pull the back off. Put the back back on, been working beautifully for 2 weeks. Today, screen goes out again, turn the tv off and back on...screen comes back again. Done that a couple times now. Anyone smarter than me have any recommendations???

Sounds like poor solder connection or faulty backlight driver

So I'm digging this up to say I think my pride is semi-bruised. After my last update, decided to buy new LED strips and driver...about $300. TV works great for about 6 weeks, last night goes out again. Calling around, guys are saying my driver is more than likely fine, but the light strips in my particular model are prone to failure. Not sure how or why, I'm just a parts replacer on electrical stuff...but I'm throwing in the towel, which sucks since the tv is only 4ish years old.

Dumb shot in the dark here...any chance there's a loose connection in the receptacle wiring and its causing funky stuff?

I've pulled, tugged, jiggled, re-soldered...not sure if I'm ignorantly missing something or not at this point, but for as cheap as TV's are...I already bought a 65" Samsung to replace.

I'm talking in the wall where the wiring connects to the receptable. Are you referring to the TV itself? Inconsistent voltage and arcing can cause funny stuff to happen with electronics.
