Unfortunately Victoria, your story illustrates perfectly the problems of self diagnosis television repair :>(

The course to become a television engineer is 2 years of full time education. Correct diagnosis is the key. Now, there may be another scenario, what if you correctly diagnosed the problem WAS the mainboard, and what if the new mainboard you put in was FAULTY? You need to skills to diagnose at component level, what each one does and how it affects the picture and sound.

My advice is to take the television and the board you took out to a television engineer. They might be able to return the board, whereas I doubt you can. It usually says 'no returns', but you can if you are a television engineer and can tell them what component on the new board has failed.

Good luck

I called LG about the clips because I could not find them anywhere.
I told them that I was looking to buy a few of the clips and they mailed me 2 of them for free in about 10 days.

Hope this helps others looking for replacements.

Same advice to my last three questions

It could be any of the boards. Take it to a television engineer. It might just be a something simple.

I have just answered a question from a lady who saw a video that said her problem was that the television needed a new mainboard. She bought one for $400, installed it herself and the television is just the same as it was before she spent $400 on a board she can't return. The course to be a television engineer is 2 years of full time education, and further education throughout the career as things change and new technologies evolve.

And another one, read this. This person changed all the boards and is still in the same mess. I guess one of the new boards was faulty. A lot are sold from scrapped sets and rather unscrupulously, not tested, but sold as is.

i have a samsung t500hvf06 i have changed all the boards no power on no sound rapid flashing standby light with back light flashing dimly on and off. any help would be great

There is no other way except a hard reset which scrubs the phone clean. Power off, hold the volume up and power button for 16 seconds until you see the Recovery Console.
