On this 55 inch RCA LED Television, when you press the power the TV screen flashes once then goes completely black. This symptom is a common problem on just about all LED television's.
Bad led backlites will cause any TV to just flash once, several times, or the TV screen will stay black buy you may still have sound coming through the TV speakers.
This is a full repair video on this RCA model LED55C55R120Q; in which we break the television down, find the bad Led strip, replace or repair the backlight strip, reassemble the TV, and were off and working again.
Thus repairing this 9 year old LED TV and saving it from the dumpster.

Incredible integrity sir. Replacing all the strips. Not many people would put in all new strips and keep the excess new strips and only replace the bad one.

Hey Bigdog, just wanted to let you know that you helped me repair a Samsung UN55 led tv. I found it beside the dumpster nearby, with your help and others I replaced the backlight strips. I was proud of myself and love the tv. Thanks so much for sharing your knowledge. I usually watch without comment, but wanted you to know you make a difference to others.

That TV must have been mounted above a working fireplace..I can't see how a power supply board could warp the plastic like that.

@bigdog8882 2 жыл бұрын

I think it was on a wall mount with the Plate covering the whole back part of the TV. Maybe that and over 8 years of the TV constantly being on. Not unless he laid it against the Furnace when he took it down. lol

for the backlight replacements, do you search the model of the tv for the backlight strips or do i have to open it up and find serial code on them and look them up before ordering?

@bradmckenzie1124 Жыл бұрын

Good video - I replaced backlights on TV. worked great until I noticed seeing the LEDs while watching TV. The backlight brightness is 50%. I lowered the brightness and can still see faint outline of all LEDs when a TV show or commercial has a light background. Could I have received the wrong LED backlights? The backlights have the diffuser (cover) on each LED. I tried shaking the tv some, but do not hear any LED diffusers (covers) rolling around. I can even see the square paper cutout of the backing paper when watching TV. I placed the screens back just like as removed. The TV is Hisense 58R6E. Thinking of leaving like as is - or trying a different LED set.

Hey there, great video! I’ve been following the video step-by-step just got my tester and tested all the LEDs and they all seem to work. I have the same TV in the same problem. The red light comes on. I got the multi meter press the button voltage is high, but then drops down just like your video so if it’s not these LED strips what could it be everything else is the same issue? Thank you.

Hey Bigdog, I’m following one of your videos on replacing the led light strips on my RCA TV and it is super helpful! Where is the best place to actually buy the led’s? I only need the one bulb/strip, I live in Canada if that changes anything.

I did but they short out again. The only tv ever where I get a small shock. I will try changing the power supply

I already changed the voltage strip and led connectors which run from the power board to the backlights

@rodwillett8814 2 жыл бұрын

Is it possible to just bypass the one bad LED, or will the change in return voltage still shut down the whole system?

U can try, depends on the TV.

I have a similar issue with my TV. The backlight flashes briefly when I first turn it on, then goes black. I don't have access to a backlight tester, but I used a couple batteries to test each strip and every LED lit up. Is there anything else that might cause this? Also, what do you use for the background music in these videos? I tried to look it up with Shazam and kept getting different results. It's alright if you don't remember, thanks!

Why does the Picture shutdown if only 1 LED is open? With no current flow in that strip, the TV should not overheat. What am i missing ? What did the test show on that particular LED strip when you tested it....... Thanks.

@bigdog8882 Жыл бұрын

There hooked up in series. So if an LED opens up, then you have open circuit. Just like the old Christmas lights.

@johnkosick1464 Жыл бұрын

@@bigdog8882 I thought there were more than 1 series circuits going to the Backlights. For example: If there were 4 different circuits driving all the backlights, then only 1 set would be open and fail to light. That would still leave 3 remaining series circuits to light the entire backlight panel, so you would only have 'dead spots' in that area. Perhaps it senses a change in current from the norm and shuts down.
