Is the inverter diode the most common issue for LED backlights?

[@tucker934]

The switching IC can be a problem, as well as the HDMI chip, and port. Also I know it’s kinda old but if used OTA Over The Air TV RF, it’s still big broadcasted just digitally in a lot of places. with a good antenna it’s quite good, so it’s still used! Lighting strikes to any of the areas “can also effect several other circuits” repetitive surging in the home can also take out components a proper surge protector can help, but it will absorb it too!

Good video simple and it's easy to find the problem. I wish my Phillips also have the same problem but for mine is quite complicated to analyze the problem I have a TV Phillips the output for the led it's 38vlts when release standby. Before release standby it shows 38vlts. No backlight on dark image Phillips appears. I have check the inverter seems only 38vlts. Do you think the inverter is bad. I have check the resistors smd near the inverter. It's beeping.may be 1 is shorted. It's solder in parallel. That's why all are beeping. In your opinion what would you do? ❓

[@tevzTVTevatronics]

You try to monitor the voltage in real-time. see if the voltage suddenly went up. It may be that you have an open led. or the driver is the problem. resistor can't be shorted if is damaged, check the resistance value, it will beep if is low resistance.

[@Fardeenfarwest]

@@tevzTVTevatronics thanks a lot my friend. No the voltage doesn't not went up. It stay on 38vlts. Yes the resistors is beeping. In my opinion the led driver is shorted.. Thanks a lot for your help. Have a good day 😉. ❤️

Hi. Thanks for the video. Excuse my fault of knowledge. How do you know the diod is the inverter??

[@Rendon276]

My TV backlight went also. While I am an experienced electronic technician, I have little experience with TV's. I wasn't sure if the fault was in the LED array, or at the inverter, or what the normal output voltage is. So I went online to find out. It turned out to be a defective diode. I looked to where the LED's plug into the board and random checked the diode closest to it, as I was working without a schematic. So in answer to your question, it's speculative. Unless, of course, you have experience repairing LED TV's under your belt. In the early days of my repair work, I resorted to random testing of components. As service manuals and schematics became more accessible, I could fault-find more strategically. But in all cases of repair work, you have to start somewhere. You work from the known to the unknown, picking up clues along the way. Such is the game of repair work. There's no set way to repair every fault. You have to use your due diligence, think logically and methodically. It makes the game all the more interesting and mentally stimulating.

@@tevzTVTevatronics and thats because of the voltage transformer right? Or is it because the motherboard regulates the needed voltage out off our 110V outlets?

Thank you for your video, but, I'd still check for short when there's no diode inside the circuit. I prefer this way cause had some mosftets shorted and they've caused the short of the diode.

[@tevzTVTevatronics]

I don't get it, what is your point...?

[@keronjoeph217]

They're is saying the mosfets that were shorted have caused the diode to short so if you didn't test the mosfets and just tested and changed the diode it's likely that the diode can short again

[@screen-protector]

@@keronjoeph217 thank you, didn't know this one. But, how to test MOSFETs for short, if everything is fine? Once MOSFETs are shorted, they stay this way and they are damaged. So, don't understand what you mean here. Can you elaborate, please?
