Thank you for your response. I have went all through both boards and there was no bulging caps anywhere. I only replaced the one I did because it was mentioned in other threads as being a common problem. I am at a loss at this point. Without testing each cap individually, which I don't have the means to do, there is nothing visually wrong that I can see.
I have Fios for my TV provider, and I only subscribe to basic cable, so I only get a few local channels. (We watch 90% of our content on our Roku, and getting local channels+internet was cheaper than just getting internet). I only really use cable to watch local news. My menu setting was set to Auto Cable. I just changed it to Cable and it is currently rescanning and finding channels. That is an improvement from before where it would just hang after 1 channel. I'll see where this goes and update this post. Thanks for the help!
Edit: Everything is working fine now. Just had to change the menu setting and do the re-scan. Thanks!
Happy to hear/read you had success! Thanks for the challenge!!!
Thanks in advance!

I finally figured it out. The screws on the sides near the inputs need to come out, as well as the nut around the antenna and then it slides out the left side with the faceplate.
I couldn't find a 470uF 105°C cap locally. Radioshack only had 85°C caps, and no electrical supply store had 16V caps. The only recommendation was to find a local TV repair shop, which I found none.
I ended up getting two 470uF caps on Digi-Key and a Weller SP25NKUS soldering kit, and shipping was only $3.94 so the total came to only $27.75 - pretty good deal if this fixes my problem.
And I wanted to give kudos to Digi-Key because they shipped my order in less than 2 hours. Wow!
I haven't soldered since technology class in 9th grade. I'll keep adding updates whether I pass or fail on this journey...
My TV recently bricked and this was the first place I came.
I promptly unbricked my TX-47F430S with the modded firmware.
TV is still kicking!
Can't convince my wife we 'need' to upgrade if this one's still working.
I've got another question about these sets - do they have a place to view the input signal strength in the menu?
I've been following this thread for about a week (the same amount of time my tv has been down)
I have a Model# TX-42F430S
Factory ID: AK (Alaska?)
Some thoughts/things i've faced thus far. I attempted first, the software flash. I downloaded it, and realized i didn't have the proper compression software, so i downloaded 7Zip. It took me a while to realize that .tar.gz and .tgz are the same thing, and one describes the other. I first archived my boot folder with the changed 1's to 0's (i only had to change ONE of the .sh files, the other 3 were good), and once i Archived it in 7Zip, then i compressed it, and it saved it as a tar.gz, which i was expecting it to save as a .tgz. I attempted the flash w/the UPDATE_WDE.tar.gz (changed file extension so it read UPDATE_WDE.tgz) and attempted. No dice, so i went back and recompressed it to read UPDATE_WDE.tar.gz and tried again, no dice.
I then noticed after reading further that i only had 2/3 green LEDs on in the back and took pictures, and read more about the bad news capacitors. I haven't replaced anything, but am thinking about redoing the 470 micro farad one everyone raves about.
Below are the pics, if you have any better ideas, please let me know :)
I replaced the 470 micro farad capacitor as others have previously said to do. I only had two green LEDs, and after desoldering the old cap, and resoldering the new one, i still only had 2 green LEDs, so the third never did light up for me. After replacing the cap, i plugged it in, and the tv fired right up! I really appreciate ya'lls help!
Also, if anyone wants a 470uF cap (same one as OEM, 105*C spec), i have 8 extras and would be willing to ship them for the cost of shipping...I'm located in Topeka, KS.
Thanks again for the help! If it goes out again I will definitely be back
