I have a Vizio E55-d0 and it has a flashing screen when I turn it on. I check Tco board, Main Power and everything was fine then I checked all the LED strips and found 2 bad LEDs. now I do not want to change all the strips because it is expensive for me, I just want to change these 2 bad LEDs (I know it may not be the right way but I want to try it) I just don't know what kind of LEDs should I order? Does anyone know to guide me. Thank You.

Re: Vizio E55-D0 and it has a flashing screen
You enquired about another model and it was advised to replace all the strips with new since all the LEDs have wear and will eventually fail if not replaced.

If you order your strips from China on Aliexpress or Ebay, they will be about 50% less than those on Shopjimmy and they just order from the same suppliers anyways. -
Re: Vizio E55-D0 and it has a flashing screen
You are absolutely right Neil, thank you for your response, I also read your blog that there are useful articles about repairing Tv, for this model I really want to try to change the bad SMD LEDs and If you can help me, I would appreciate. But I do not know what kind of LED is compatible 2835, 2538, 3528 or ......Comment

Re: Vizio E55-D0 and it has a flashing screen
I rarely do single LED replacements anymore. It's usually the crappy RCA models where you can't find new strips. I have found that for most models you can use Samsung compatible 2835 1W 3V LEDs with the wider pad negative. LGs use a reverse footprint with the wider pad positive and some LG models use 6V. I have sold off most of my excess modules.
I have a Sharp Roku 50LB coming back where I did a repair only and turned down the backlight level and it lasted almost 2 years. Ordered a new set of strips for it. Price of strips has come down in the last few years.Last edited by neilc6; 10-10-2021, 10:56 PM.Comment

I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.
The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While... -
Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!
My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.
This time the original cable broke too close to the screen, it can't be fixed without tearing the screen... -
HI all,
hope someone point to the possible issue before I start buying replacement parts.
Tv starts normal and responds to remote fine, PSU voltages mesured fine 19v was 18.9V under load and 19V with main board disconnected.
Backlight stays on all the time,
Sound works fine.
screen keeps changing form black to full picture in about 1sec intervals.
Picture looks fine with no visible artifacts.
I have disconnected backlights and flashlight test confirmed that picture is still doing the same.
Disconnecting left and right ribbons on... -
Hi,
I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on... -
So our beloved M60-C3 up and died the other day. I was not there, my wife mentioned that it came on, displayed the logo, then showed the right half of the screen white and fuzzy, with the left half of the screen ok. However when I got around to looking at it, the screen would not come on at all. The indicator LED will come on, then dim a bit. After a while, the LED might blink a bunch of times. I can't get it to be consistent to do that.
So I've got the back off and am checking voltages. The capacitors on the power supply board visually check out. No bulges or anything. They all show...
