    Hi ALEX ,I like those video's the best.When you repair stuff if you DON'T run into problems the video is great for a repair on the same make and close model of the item. BUT when you run into one that makes you fail a few times ,i learn HOW you are making a decision on where to look next and why.When the 133x component read close to the same on both ,that was great.we could see your disappointment.At that point the next step was where we all learned with you.

    It is a pity that the manufacturer does not provide professionally registered establishments such as yours with the circuit diagrams. Okay, I understand copyright, etc. But, you are providing an excellent service and the manufacturer could provide you with screens too. Plus much more. Well done. I am a professional at nearly seventy years young and still employed in the electronic service industry; I find it be be interesting and really enjoyable and a challenge. Brilliant and logical fault finding, thanks for sharing, as always.

      @@Gigaheart Auto manufactures have admitted more than once that a vehicle can relatively easily be developed to last a million miles with minimal maintenance. That's including chassis and drivetrain. Then they would sell fewer cars, meaning less profit for the fat cats.
      Toyota accidentally did make a car like that. The 2000s-era Lexus big body LS keeps on going well past a million miles on the OD, but the word is out, so not cheap if you find one.

    52 years ago my brother in law had a portable Sony TV that stopped working. I asked if I could look at it & he said yes. I took a spare wire and attached one end to ground and started touching the other end to resistors. I touched it to one and the TV started working just fine so I soldered that wire in place. Some times all you need is luck, I was 11 years old.

      All useful vehicle tuners are expensive.
      If it can be fixed, it's well worth it.
      I spent 700 on one for my Honda 11 years ago, still have it (and the car). I want to get another for my truck, but I don't really want to mess with too much on it besides firming up shifts so I haven't justified the cost, because it's just as expensive.

      It's normal for the diode to heat up as well as the two other components on top of the board. That is based on my finding inspecting many good working tuners under a thermal camera.
