I'm looking for a manual for the power supply board for my LG 1510SF

The LED power comes from the main power supply, it doesn't have a separate supply for the backlights on this model. I don't think this is the issue though if the colors are off, sounds lmore like a tcon or panel issue

Below is a couple links for the board you need, shopjimmy is out of the board and personally I'd wait tell he gets one in, ordering boards on eBay is kind of risky, a lot of people stripping TV's that are laying along the road or where ever, the boards are taken out and sold, figuring at least one board is good in the set where shopjimmy actually tests the boards and will help if you need it...

If you saw no faint picture with the flashlight, then it's the T-con board.

Hi, checking user manual there's no soft reset option so maybe the main board is faulty too, usually when there's a damage by lighting in power supply this also reaches the main board since they aren't electrically isolated.

just look the amper rating in the power supply if they are the same.

did you tried already to replaced bulging electrolytic capacitor at the power supply.

Hello Alan,

That is actually not power saving mode, the flashing power light indicates the power supply is not starting up correctly and keeps shutting down and trying again. This is a very common symptom of a failure of the capacitors on the power supply board. The L1752s uses the AIP0157 power supply board which is the same board the is used in several LG monitors such as the L196WTQ and L194WT. Here is a link to a repair guide for the L196WTQ that shows what capacitors to look for and replace on the power supply board to bring the unit back to life.

please use these service and training manual, to troubleshoot and service.

You need to pull the power supply out and replace the damaged caps on the board. Look for swollen, pushed up tops and leakage around the base of the caps.

You need soldering and basic electronics skills. You also need to pull apart that big tv and pull the power supply board!

You can look on Ebay for pullout boards from people who have broken their screens. It can get you a working board for cheap sometimes!

Good luck and be careful!

Service manual from SAMs does not include a schematic of the power supply board
