Question about Insignia Televison & Video
I have an Insignia NS-LCD26A TV whose power instantly went out. I waited a while to remove the back cover and once I did, I discovered several capacitors had leaked plus some were tipped over. This was all on the power supply board. Some of the (now) dried chemical got on the wire head leading to I think either the LED driver board or the T-Con board. I was unable to remove the main board/motherboard's cover but the capacitors on the outside of the cover looked to be in good condition. The part # for the power supply board is: 6HU0122014. The main board's part # is: 6HA0226911. Is it worth trying to replace potentially two parts? I know for sure the power supply board is in need of a replacement but I am not confident about the main board even though no leakage spread onto it. Note: I received this TV as a gift so I put no money into it.

Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I unscrewed all the screws in the back, detached the tv from the base, and was able to get the back off. I ordered a new power supply board and will install it to see if it fixes the problem with the tv (won't turn on, insignia light alternates between red and blue). I didn't notice any problems with "swollen" capacitors, so if the new power board fixes the problem I'll update this website.

I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.
