Thank you very much for your video uploading.By the way, it is possible to cutoff end of solder suker with small scissor,And It will make you to use your solder suker without detach soldering tip from pad as you did in your video (4:50-5:10)
Awesome modification, excellent repair! Yes, videos do take a long time to produce, I have some from 6 months ago that I haven't edited yet. It's hard to do both - work and edit videos.
Hello sir.your videos are perfect and very helpful.is there a way to contact you for asking questions about tv repair.i repair tv and others too.thanks
Thank very mcuh for reply! I plugged in AC cable and checked DC voltage of AT24C04 IC which seems to be eeprom for this 29 inch LG CRT TV.I placed red probe to pin #8 of AT24C04 and black probe to pin #4.It measured 5.084Vdc regardless of clicking power switch.I also pressed channel button and other button on the remote controller But It won't make LG 29 inch CRT TV to display any screen at all...
@@bshi0288 just hang it and try it, if the tv turns on it? it means it is in standby mode. or it has an EEPROM program issue. Check if you have a remote try to remote it, but resolder back the EEPROM before you remote it.
@@tevzTVTevatronicsI resolderd all pin of EEPROM(AT24C04) on the bottom of PCB and I repeated to plug in AC cable and push power button on the remote and unplug AC cable, more than ten times. I noticed that whenever I push power button on the remote,DC voltage of B+ filter capacitor(160v 100uf) suddenly became 120Vdc and it gradually decreased until it reach 38Vdc.But Unfortunately, No matter how repeat plug in, push power button and plug off,It won't display any screen at all
@tevTV, what kind of device do you use ? To Discharge you're Capacitors ? Do you use a ground Clip, attached to wire, attached to a Resister, that attaches to Discharge metal Rod, that you simply touch to main, Capacitor.+ Positive Terminal ? For 5-10 seconds ?
hello Mr tevs,I, didn't see your for long time, where are you, may be you go to travel or you leave your house ,or something else ,so are you ok or something wrong?I hope you're good health,but I have a question,are you from maylasi,or Singapore or in the area of nearest,
I have 29 inch LG CRT TV which did not display any screen at all. When I plugged in its AC cable I measured DC voltage of B+ filter capacitor(160v 100uf), it measured 38Vdc with DMM. But as soon as I click power switch,It suddenly soared to 120v and gradually decreased until it reach 38Vdc. And I also measured pin #9 of STR-S6707 in the HOT area with analog meter and it also soared to 7.3-7.5 Vdc as soon as I click power switch, and gradually decreased until it reach 6.4Vdc. I purchased another STR-S6707 and replaced primary STR-S6707 with it by soldering but that would not fix this voltage decreasing problems.. Would you give me a clue What cause this symptom of decreasing voltage of B+ filter capacitor and VCC of switching ragulator?
Some power supply goes to a lower voltage when the system is in standby mode. try press the channel up or down or other power booton. Check also the 5 volts standby.
We can learn from our experiences and knowledge. Even Chimpanzees are capable of innovation. They can come up with new ways to solve problems, such as using a stick to reach termites out of a mound.
