#221 Repair ICOM IC-7300 with Power Loss

I'm equally intrigued each time you work through the circuits (and in detail) to troubleshoot these radios and thoroughly enjoy listening to your wisdom that has come from many decades of experience.. thank you again!

When all is said and done, only one conclusion. Genius at work.👍☘️

Great video Peter! This has to be one of the most interesting videos that you have made. I thoroughly enjoyed it!

Another good teaching hour to learn more about radios. Thank you Peter

I have an Icom IC-7000 that was behaving the same way. The problem was also one of the finals. It is interesting to watch you troubleshoot the problem because we approached the troubleshooting process differently but both determined the finals needed replacing. I enjoy watching your videos, thank you!

Very good troubleshooting Peter, a pleasure as always learning from your experience. Thx for your time, hoping to see next one.

Thank you Peter. I feel further educated about fault finding, about finals adjustment and modern set reliability. I was thinking of buying the 7300, you have taken me a step closer. Regards Andy

Like everyone else says, excellent troubleshooting technique along with layman's explanation. My hat's off to you sir!

All your videos, lessons really, are most excellent. Thank you very much.

You are the man!! I love watching you work through these repairs

Thank you for your video it really helped. As you know at the end of this video you showed us the proper way to adjust the idling current. That was very important can you also show use the receive adjustment, the TX power adjustment, TX amplifier adjustment and the frequency adjustment on the icom7300 I have learned a lot from you and to be honest your the only person that I trust with teaching and your attention to detail. Once again thank you from KG5ZLO

I just love watching you repair these radios I am not good with electronics but its really great to see you work and explain what you are doing ..Thanks for another great video

Great Tutorial !! Just knowing where the different placement of the various boards are located, is a wonderful start to getting to the next step in place!! Your showing the physical locations of the PA driver board, and cables, will stick with me when I eventually purchase my own 7300. What a FANTASTIC tutorial!! Thank you TRX Labs!! Your statement of replacing BOTH PA's was interesting. I assume that was done because your logic is that the good PA was way over-stressed, (demonstrated because the 7300 got to NEAR max power-out, with just ONE PA ALONE, causing the life-expectancy of that good, single PA to be radically diminished). The latest firmware installation was ANOTHER point of interest as well!!. I am GLAD that Icom has provided diagnostic information/settings, as well, that is accessible on the front-panel readouts!! Thank you, AGAIN!!

Excellent video Peter: Bit of an unusual fault but succumbed to your logical diagnostic process, a pleasure to watch as always.

I always enjoy your videos Peter and so glad you’re back!

Fantastic! I own this radio and so I appreciate the peek into the schematic diagram and the beautiful problem solving process. Perfect! Well done! Thank you once again for all you do. It makes a huge difference! 73, de NZ5I OP Kenny (ex DJ0SI)

Great repair video as always! Thank you for teaching us.

Very interesting repair. I have a friend with a 7300. He has no problem with it yet but I will send him a link to this. Firmware update is more important than I thought. Learned alot from this. Thanks Peter!

wonderful explanation of how to troubleshoot the final transistors !!!!!! Thank you!

Outstanding fault locating. These new computers, I mean Radios are tough to work on with these PADS components and huge IC's. Well done Sir!
