[@QTheMost]

Hey I have a question. I have a led samsung. It just stopped working. Sound is there and I flashlight tested and see stuff there. So the back lights arent working. Is it safe to say I need to replace the LEDs? Where can I find the LEDs the model takes?

[@canavlogs598]

I have a 55" haier 4k ultrahd It has backlight but I dont see a tcon board help thanks

[@midwestfishing9153]

HI I have a lg 55 inch tv and when I power it on the sound works but the image flashes. It will be dark then u can see a flash of the image then dark again, it repeats this process. When you can see the image it is clear and sharp any ideas of what my issues is.

Hey does this wrks for JVC brand also I have that same problem

[@bob55today]

Your repair vids are my favorite. My respect for you has grown, knowing you're confident enough, to not HIDE, that even pros don't always have things go ... perfectly.

[@rayofcreation3996]

Great video. I have an lg tv and I hope it never quits but if it does I will try and fix it because it ain't no good the way it is and if I screw it up I was going to throw it away anyway👍

Hey i just wanted to say thank you, i dont have the same model tv but this video helped me diagnose the issues i was having! so excited to get this fix done, its a 50in highsense smart tv my sister gave me for free so a 50-60 dollar fix is a sweet deal! Again thanks so much!

Great video, and thank you for not editing out the screen drop! We learn from our mistakes, and hopefully from others as well. 😊👍🏻 Oh I was corrected by a grammar nazi years ago, the "L" in solder is silent (WTH?)☺

[@richardking1373]

Thanks for that! I have just dismantled a Philips TV, following your instructions. Not sure if my client will invest in the led strips... I used a 24VDC supply for checking the leds, soldering the wires on the test points of each strip.

[@Gunnerblaster]

Neat video. Nice to know what, exactly, is wrong with my TV. Unfortunately, I lack confidence in my ability to safely disassemble and reassemble my TV :P

[@habtamusium8646]

pleased to be in this class today . many thanks .

[@wavecutter69]

You seem surprised that it actually worked after you repaired it. Great video by the way. I shared it with my friends kids hopefully they find it really cool to fix things that are broken. Hope to inspire them to set up a small repair shop.

[@rayofcreation3996]

Thank you so much brosef. Kind of you. Good luck there and cheers! 👍😊

[@douglasbrynteson6556]

tampatech, love the vids! you've stretched my know how in electronics and also teaching. you got a gift brotha! I have one issue tho. I have a kicker zx750.1 mono amp. I have the circuit board exposed for show purposes. I usually have a custom cover but had it off at the time of this incident. I had a lot of water fill up the amp but it's suspended in air so it was draining instantly somewhat. I caught the problem and got it out immediately. the power was not on nor was the vehicle. I have 2 500k power caps right by the amps also. they got wet, but seem unscathed. I immediately took the amps out and blew them out with the air hose. then disassembled them to further dry and inspect. I did the big one first cause it's more valuable. a kicker 700.4. got it reinstalled and works fine. now I did the 750 the next day. got it in and it lights up and produces audio but a green little capacitor on the board buzzes. it's almost a wave effect. slowly gets higher pitched and stops. then restarts. if I grab the amp and twist hard I can make it stop. once I let go it starts up. I've taken it apart now and touched areas that looked suspect with a soldering iron 5x. even replaced the green capacitor which is a 2a102j. I'm stuck and tired. any direction would be much appreciated.

[@bikeamtn]

Good video; but also liked the 'Well That Happened' incident with the panel (and you took it well). Being a tech/engineer in a few fields, WTH had us amazed and humored many times.

[@mikebarton1102]

Thanks for vid Tampa! Couldn't help notice number of LG sets that seem to have backlight issues! Maybe LG ought to up there QA processes in that area a bit!

Thank You so much for posting this , Big Help!!!

I prefer to use two suction cups to remove and install the LCD screen when working solo. More stable. Nice job with the fix!

[@DrRestorations]

Hi Paul: To avoid accidental fall of the screen glass, is it possible to work on the TV with the glass side on the table and lift the metal back side up (turn 180 degree) for repair?

[@mul7777]

Great video. I have a LG 55ln5600, on power up screen flashes them black. Measured 180v going to led strips then voltage goes down to a steady 84v. Bad led strips?

[@onthatdove]

Hello Tampatec, I've watched some of you vids a year ago, just noticed you had so many and your own channel. You're such a help to all of us diy folks. I have a Sceptre E55 and it powers on and I can see "select input" image on screen ONLY with flashlight and dark room. In this video, you state that if image shows with flashlight that the tcon board is good. When testing the voltage on power board to LED wires, no volts in DC mode, but 3.2v & 3.5v in AC mode (two connectors going to LEDs. What do I check next? Some other vids mention backlight inverter.

[@jasonkok174]

Fantastic. Keep it up. Truly......superb.

[@TheIndyguy2000]

Awesome video...plus I just got a new 49" LG TV...Thanks!

[@TampaTec]

Kurt Baker to prevent this repair from happening just keep your backlight and your brightness settings to 50%. 👍 subscribe for more tips

[@samuelbolanle1994]

Thank you fo this video. If I may ask, is it true that once a diode is blown on the powerstage, the entire powerstage is damaged? Can't the component on the power stage be replaced, if the need arises?

[@classycookery]

Very good information to all

[@TampaTec]

COOKERY AND CRAFTS CHANNEL thanks

[@vasel208]

👍👍👍👍👍👍😊 Excellent job. I have a question. Does the way you test LED TVs apply to 8 inch color touchscreen monitor used in cars?

[@craigkennedy4519]

First of all great content. I have a 65UH5500 (2016). When I power up the TV the screen lights up then goes dark and the red light (power button) flashes 3 times. One long flash and the two shorter ones. I checked the capacitors and they do not show any signs of damage. In addition I could not see any images on the screen when I used a flash light on it in a dark room. However I will say there was a slight odour from the Tcom board area. Any suggestions of what to check next. Once again great channel with very useful tips and information.thanks

[@miguelmaldonado4433]

You got Good Karma my brother positive energy that's why that screen didn't fail you keep up the good work brother!

Hi Paul. Love your videos. I have a kdl40ex400 and on power up the screen flickers, has a thin red line across the bottom and will eventually black out but still have sound. None of the videos address this condition. What do you think it could be? Thanks in advance.

Great video!! I have a LG 55LF6000-ub. My screen turns black when it comes on but it flashes the picture which is still a good picture. Thru the screen when flashing there's 1 row in the middle that flashes led lights along with picture. I can use a flashlight and put next to screen and I can barely see the picture. Audio works. Would this be a problem with backlights?? Any help would be greatly appreciated!! Thanks 😎

[@user-wb3bq6wi2k]

Hi Paul... your vids a great, enjoy your style and like to see your son with you as well. Our LG does not go black, the picture screen blanks to a variety of colors. I have photos of it. We unplug to reset, and picture returns. However this is a persistent issue, mutliple times in an hour or day. Any suggestions what it could be or how to fix it?

Hi Tampatec i have a LG 42LN5758 my problem is when i turn it on the power led is blinking 3x the sound is ok but the picture is blinking always in dark to bright you can see the picture with a flashlight cleary Thx for your answer

[@mikeoleksa]

Would not removing the old glue from the LED strip cause a "halo" effect shining through the screen when the TV is reassembled? It makes sense if the height of the lens is that sensitive. Everything works after replacing the LED strips in my LG 55LB5900-UV. I just have the "halo" effect on 3 lenses I had to glue back in place. Or is there a specific super glue I should use? I used Loctite brand in my repair.

[@AlCatrraz]

Did you ever use an LED from a different TV brand to fix the backlight I have a broken strip -- but working LEDs -- from LG TV and I want to remove the LEDs and place them on a SAMSUNG strip.. Thanks for your videos and advice..
