Fixed an old CRT, but it started smoking after I turned it off. Need help diagnosing problem component(s)
Hello and thank you for taking the time to read this. I am new to CRT ownership/repairs so please let me know if this is not the appropriate sub to post this. Would also appreciate any suggestions on where else I can post this.
I was given an old Magnavox 19PR14 C222 (chassis 19x608-00aa) that would not turn on. After opening it up, I saw that Resistor R432 had burned out. I was able to find the schematic for a similar model and determined that this Resistor is 1K 1/2W. I replaced it with a carbon film gold band 5%. (Perhaps the wrong type of resistor?)
After closing it up, I managed to turn it on! Per the video above, the static video and sound came through. (The image wobbled quite a bit... a possible symptom of a larger power issue?) But when I tried to turn it off, it TV did NOT power off all the way. The sound cut out and the static video only dimmed. That's when I noticed smoke coming out from the top vent. I quickly unplugged it from the power source.
Upon opening it again, I saw that the replacement Resistor R432 had burned out again. So I'm back at square one and ready to ask for help. I managed to find this old forum post detailing the same issue I'm experiencing. Unfortunately, it's in Spanish and even after Google translate, it's still all Greek to me.
I'm guessing the issue lies with one of the components related to the on/off switch but I'm not versed enough at reading schematics to determine which ones to check/replace. I would appreciate your guidance on where to troubleshoot next. Thank you again for your time.
