I have a Sony 49 Inch TV. First repair project, I have been working on it on and off for a few months now. I am at the same stage. Will check for shorts on those screen boards and wait for part II of this video. Thank you for your work.
this is a very interesting video . and you are a good detective also . this video has many lessons in . on how to start diagnosis the bad components .and how to start step by step . So if the COF is really bad so need to remove it and if the cost of bonding machine cost a lot and if the client will pay for such work .or the client prefer to put it in carbage . Well that was a very interesting video . keep it up thanks for your time for this wonderful video . great lesson happy new year .❤️
Thanks for sharing your determination to fix that tv .. i would have thought t con also but I have see bad main pcbs being bad causing similar problem on other brands.. I hope you get to root of problem
I find this so interesting how you diagnose electric problems. These tv's they make today are made to fail. They want you to buy new ones every few years.
Around the 27-minute mark, you tested a capacitor measuring about 100 ohms. Why didn't you suspect that capacitor or another capacitor in parallel? Do you use a short-killer tool? Those diodes appear to be protection diodes, with one end grounded and the other connected to the rail they're protecting. I think you should use a short killer across the cap if you have one. Be careful with the polarity of the voltage you put across the cap because you can have negative and positive voltages on that board. All the best
Can you share the link to the tweezer meter. Great video as always. I have a 55" Westinghouse with the same problem. 2 years old to. I've fixed 4 TV'S so far out of 10. Great hobby for me I've had a stroke 7 years ago that disabled my left side. So those tweezer meter would be ideal for me. Thanks for sharing.
Hi Big Dogg, I have a one year old TCL 75S451 75" LED TV that has no picture. It gets power, it's backlights come on, I hear a sound as it comes on but I have no picture. I have replaced the t-con board but have the same problem. I ordered a power supply board to try that, but I am not confident that will solve the problem either. I should mention that the remote with new batteries will not turn on or off the TV either. I did shine a flash light on the screen as well but didn't see anything, it just has backlights. The TV only has the 2 boards inside other than the wifi module and the 2 long, skinny video boards at the bottom of the screen. What are your thoughts for the next move or part you think I should replace next? Any feedback is greatly appreciated and by the way, your videos are awesome! Keep up the good work. Thank you and hope to hear from you soon. Jerry

Yes, it could be T-con, or main board or even the panel.

1 bad bulb again. Mass production.
Looks like you have a solder bridge between R107 and Ri08 or maybe a piece of solder.
🔥🔥 Thank you!
