Thanks Humberto. They are pretty good tools for what I can afford. People that have more money have much better tools than I do.

Thanks Eric. I am glad that you enjoyed the article. I explained it to you in the comments on Albert's TV repair article. I basically just use a piece of plyboard covered by a thick towel in one hand while lifting the panel up with a suction cup a little bit. Then I just slide the panel onto the covered plyboard and set the whole thing down on a table.

Thanks Andre. Yes but the LED's were good, just cold solder joints. The LED tester seems to do a good job. I haven't had time to test it on components yet.

Thanks Albert. I'm pretty sure that I had to pay for the service manual, but I don't remember for sure. I figured that someday I would need it. I'm not sure how much fumes would come from a few small dabs of superglue. The E6000 is a high-strength adhesive. I am hoping that it can handle the heat of the LED's. We will find out.

Nice Jon Robert, Nice to know that the TV was working and just the back lights failed. I have to buy one of those LED testers, its a nice tool to have. Thanks for sharing.

You were smart buying that service manual for your 40 inch Sanyo tv too in case you would need it Robert! The photo of the 122V at 59 mA working backlight leds with not all refractors glued on yet is a perfect demonstration why the TKDMR Model #TD3H backlight/component tester is an improvement over the standard testers without those extra pots. And using the small dots of E6000 adhesive glue was something worth knowing too! Using normal superglue can negatively effect the transparancy of the refractors because of the cyanide fumes coming from the glue. But knowing there are so many types of glue like E7000, E8000, T6000, T9000 or B6000 I am unaware of their specific application.
