Toyota Corolla Radio W58810 repair (intermittent no sound)

[@janipuumala9809]

Thank you for this video. I repaired my radio as well by soldering these power transistors. Remember to solder them from both sides, as the through holes can be damaged from vibration. My radio had almost none tin on the component side of Printed Circuit Board, so it was possible that the through holes of PCB were damaged and current couldn' flow on the other side if I soldered only the bottom side of Transistor legs. By soldering from both sides I ensured that a damaged through hole wouldn't matter as the transistor leg is taking care of moving current from side to side.

[@tibitek]

Thanks, this has worked! (I soldered all the power transistors from the top side of the PCB too.) You have saved me hours of "debugging".

[@givi6358]

a big thanks. now everything works ok. it was almost all detached! Gianni from Italy

[@silviadelatorreugarteflore1388]

Thank so much for your video. My radio had the same issue since three month ago. (Corolla verso 2006- Spain ) I will weld transistor No 1 in the left, this is the faulty one and it fixed the problem. I think it is a defect from Toyota you showed very clear. Thank you other time.

[@andrewbuttigieg2824]

Exact same problem I have with mine. Good to know of a fix instead of 300+ euros to "repair". Thanks for this!

[@gussed6485]

Hi, thanks for this fix, got my corolla verso 2006 radio to work after I soldered all 4 transistors.

[@hectornavas34]

You are the man!!! I suspect something similar but your troubleshooting have been amazing. I don't have some many toys to play. Much appreciated.

[@marekstraka285]

Thank you a lot, you gave me the motivation to repair mine. Had almost same symptoms, just the display was turning off as well when failing. it was sensitive to vibrations, temperature and length of being turned on. Like a year ago I took it of and reslodered all the connectors and few holes, but it just lasted like 1 month (have not fixed anything obviously) Based on your video, I resoldered again, with focus on transistors, which made sense as it was sensitive in same area. However, without success again. But as you showed me there is service manual available and I really don't like to lose against IT or electronics problems, I spent some more time on it and traced the problem down to IC704, pin9. After resoldering resistors R797, R799 and R796 it is working like charm :)

I dont mean to be offtopic but does anybody know of a tool to get back into an instagram account?? I was stupid lost my password. I would appreciate any help you can offer me

[@jaxxanthony5350]

@Roger Paul I really appreciate your reply. I got to the site on google and I'm in the hacking process atm. Seems to take a while so I will get back to you later with my results.

[@jaxxanthony5350]

@Roger Paul It worked and I now got access to my account again. I'm so happy:D Thank you so much you saved my ass :D

[@t.w.8822]

Thank you, top and great analyisis! I will open my radio a third time now and try to fix it.

[@marzenajonsson6555]

Thanx so much for helpful video. My radio had the same issue. (Corolla verso 2006- Sweden ) I resolderd all 4 transistors just to be sure and it fixed the problem. Transistor No 1 to the left was the faulty one but the other 3 were bad as well. Greetings from Sweden.

[@gaborbak9278]

Great video, thank you very much. It seems, you are an expert. Unfortunately this solution didn't work on my radio. The sympthom occurred again after the resolding all of the transistor legs. Have you got any tips, what could be wrong with it? Which direction should I go?

[@Mojo-cg3xo]

Hi, get step by step instructions, I managed to fix my 2006 Corolla radio. I have a 2014 Corolla touchscreen radio with Bluetooth and it’s constantly rebooting even after resetting the radio it’s stuck in an endless reboot. Any suggestions on how to fix this??

[@t.w.8822]

Hi, just fixed it, great work! I am so happy, thank you!!!😄👍

[@kostelectronics]

Congratulations! :) This is my goal, help others! BR from Switzerland!

[@ennecarsmeccatronica2273]

Excellent repair but above all excellent CD!

[@IsikUgurlu]

Mine is Corolla 2002, NOT Verso, but the problem is exactly the same. Audio system model number is W58802. Unfortunately those four transistors connected to a heat sink do not exist on this model. I could barely detected 3 transistors located here and there. Applying some pressure on them had no effect. So it is a dead end for me! Thanks for the video anyway.

[@Snurre86]

I have the 2003/2004 model car. Not completely the same radio, the back light does not flicker but the sound was intermittent for a while then completely left. The volume does not display when i adjust it, but I don't know if that is normal. I opened and solder heated the 707 contact points just to get the solder re-seated but no sound still.

[@sarahwilliams170]

Hi was going to take a look at my car radio cd player, it won't turn on, 12v to the back of the unit, ground good and ignition good. What do I need to watch out for as for as this warning is concerned "Hazardous electromagnetic radiation when interlock defeated"? when I open the unit. Also any ideas on the likely faulty part. Thanks in advance.

[@saarike]

Now that was interesting radio to fix. Thanks for vid!

[@borisrud1286]

Nice work, have the same problem. Tank You!

[@sinusvag]

Nice tutorial! Since you have the schematic, would you be able to give a hint on if there is a stereo path on the pcb to the amplifier section? I am planning to "enter" that path, cutting it, and installing a bluetooth module which passes through audio when not connected. Or if you know where the schematic can be found? Many thanks from Sweden

Нихера она тут не стандартная, там беда с нулевыми резисторами в цепях этих транзисторов стабилизатора, такое чувство, что их туда поставили спецом, для бужущих проблем. Одно не понятно зачем такая лаборатория, что бы решить эту детскую болезнь.
