Re: is there any courses to get certified in fixing tvs
Some stated require licence. Louisiana use to but stopped due to budget cuts. If you want to learn component level electronic's, I recommend E.T.A. or ISCET. I am a member of both. They give you list of topics and books. The exams are proctored. There is a basic knowledge exam of core electronic then another exam for your journeyman, industrial or consumer electronics and so on.
The test are difficult, but if you pass your paperwork will set you apart from the others. I have seen people who can pass a test and not able to fix anything. I have seen people that can fix things but not pass a test. If you put a lot into it, you will get alot out of it.
Most places only want board changers, this does not require a lot of knowledge. Component level repair is hard and most Service Manuals don't include schematic anymore. They want you to buy a new board instead of repairing it.

Here's a video I uploaded to show the problem.
https://youtu.be/MbaZQ7aYMMY?feature=shared
Quality isn't 1080p yet because I just uploaded it. YouTube takes a while to process videos to maximum quality.
I have a multimeter and basically no electrical fixing knowledge.
I came across a post on here describing the same issue if it helps y'all help me. -> https://www.badcaps.net/forum/troubl...500-done-today

Hi friends of electronics
What you see in the video and pictures attached is the circuit for charging the batteries of a DC motor.
The problem is that this circuit cannot charge the batteries (3 1800mAH NiMH batteries) any more. When the circuit was OK, its green LEDs lit up one at a time to show that the batteries have charged more. But now that the circuit is flawed, LEDs light up as you see in the video and at the same time successive beeps are heard.
Please help me fix this circuit.
