Is 3v standard per LED?

If so shouldn't I be seeing an output closer to 110V then and maybe my output voltage is low?

Re: Haier 50E3500A - No Backlight

I thought I checked them all but I suppose I could have had a brain fart and skipped one strip. I really don't want to remove that 50" LCD again but I suppose I should probably just do it and check them again. Every time I have to remove a bigger one my heart rate doubles haha.

Hi,

I'm fairly new to electronics repair (I started with mobile devices) so please forgive me if I am not as clear as I should be.

This LCD tv has image but no backlight. The backlights flash on for a spiit second when powering on the tv and go out. I spent a lot of time looking for a schematic or servicing manual for this TV but I was unable to find one. If anyone can point me in the right direction in that regard that would be amazing.

I have checked all the output voltages from the PS board and all of the ones that are listed on the board are good....

Hi,

I am fairly new to electronics repair but I love the challenge of it. I currently run a very small electronics repair shop that mainly focuses on mobile phone and tablet repairs but I have been getting more and more requests to do a wider range of electronics devices, which is what brings me here.

I continue to be astounded by the number of people out there willing to unselfishly share their knowledge and experience. So thank you to all who contribute to this forum. I hope to one day be someone giving...
