I have a 50 inch RCA tv that is only 3 years old and now some of the SMD need to be replaced. My question is I have some 3030 1W 6volt I would like to use and the SMD on the tv show 2.5 bolts with a Led tester. Can I use the 6 volt for this replacement?

Re: SMD replacement for tv backlight
No problem, just take it slow, be very careful with the panel, when you put the panel back in take EXTRA time to make sure it's in properly, a lot of the failures are from folks tightening up the frame with the panel not in right and it cracks, maybe check some youtube backlight replacement videos on same or similar models and be sure to test the new backlights before installing.Last edited by nomoresonys; 07-30-2023, 08:41 AM.Comment

Got problem with a samsung UE55JU6875 after replacemant of backlight
I have done similar replacement several times before without any issues but now I got video problems after the replacement and do not understand why
Attached picture of the problem
Is it a bad panel or any issues with the T-con card or ribbon cables or bad connections?.
I have tried to replace both ribbon cables from T-con to panel without any difference.
Any ideas?
The only misstake I might have done was forgot to remove the ribbon cables from the T-con card before... -
This TV has been on the wall in our reception area for around 10 years and the other day the backlight failed. You could see a feint picture so we knew the screen was OK. I took the TV apart to get to the failed backlight and inject voltage in to each half of the LED strips to identify which ones had failed and 4 needed replacing. I ordered a set off of Amazon and they arrived the next day.
On fitting the new LED strips I plugged in the TV was blinded by the light!!
It was only when I partially put it all back together (including the screen) that... -
I bought this p2210f dell monitor to fix. Schematic is the same as p2210.
Behaviour is that monitors comes on but then backlight switches off almost instantly. If I look with flashlight I can still find the "No signal message". So definitely a backlight issue. Trying to advance the issue I proved that the protection circuit is switching off the backlight by shorting out C3 and resistor to disable the INL chip then re enable by removing the short.
This is where it gets interesting. When I disassembled the monitor to solder leads on c3 capacitor I noticed the backlight flickered... -
Hello all,
Am trying to figure out this backlight issue with this A1990 Macbook Pro.
Tests performed:
There is no backlight even with a good screen.
Backlight IC is receiving the correct support voltages.
Fuse F8400 ok
Current sense resistor R8400 ok
Backlight IC is receiving 3.3V on enable pin.
Backlight IC receiving voltage from PPBUS_G3H, aprox 12.5V.
Backlight IC receiving 5V from PP5V_G3S
Backlight IC BKLT_SCL and BKLT_SDA both measure 0.545V diode mode to ground
I2C_BKLT_SCL and I2C_BKLT_SDA both measure... -
Hi,
This TV uses 2 bottom edge LED strips. 1 was faulty but replaced both. However I have still noticed that the RHS of the TV switches on and then TV starts to recycle power getting to the LG logo and start over. If I disconnect the RHS LED strip will work with half screen lit. I have swapped LEDs and same problem.
The power supply uses MAP3516 chip. Have replaced it twice, Checked all components as greatly suggested in this post https://www.badcaps.net/forum/troubl.../101580-lg55uh...
