The most common elusive problem we encounter in electronics troubleshooting; gadgets where some manufacturers using these adhesives that turns into a dried substance, overtime, that causes corrosion on the component terminals. More often they create a short path resistances that can affect the circuit during operation. A dried part of an adhesive literally turned into brittle dark brown colour will give a reading below 50 k ohms on the RX100K range on the multimeter. To a beginner these are sometimes unnoticed, so its better to have thorough inspection on the circuit board, a keen observer with a good eyesight.
@@tevzTVTevatronics Commonly seen on amplifiers, these kind of adhesive, the purpose of it is to make the electronic component intact and wont detach due to vibrations and heat such as electrolytic capacitors and slot boards. On some old CRT televisions, Computer SMPS units, they use silicone glue or a glue stick.
Maybe you should have removed the two capacitors and connector that were touched by that black gunk and remove it completely, then reinstall them if the leads are still decent. Now you fixed the resistor but a few months from now the leads of the capacitor near it may break apart, or the header nearby.
Hi dear tevz again and i saw something new. It seems that The differene 21 ohm can not caused this problem and i think when this resistaer in the circuite and turns on the set 350 ohm turns into the megga ohm and so the 17 volt is ubsent or high less !!! What do you think tevz?
I learn a lot from watching your fault tracing process . Thanks again.
Great to hear!
Your way of tracing the fault is very nice and perfect , I like the way you handle the sets , calmly and easily.👌👌
Very instructive, hopefully you can still measure the résistance....good work !
techer good works exelint information
🤝
Hi dear tevz
It was a great job

Lock like the manufacturers have a purpose of using that adhesive. It gets resistive over time and the circuit will fail.

Nice video sir tq
Good evening sir good job as usual ❤️
Good morning!
@@tevzTVTevatronics good morning you too.
Nice Repair.
Thanks 👍
Good information sir
Thanks
Good morning Mr tevz ❤
Good morning
Very good explanation Sir . Learn a lot ...Thks
sir i want a video showing me how to check SMD capacitors in circuit through resistance analog
multimeter
Thanks.
Hi
The best❤❤❤
Like the Saw blade for a pry tool
Nice work
Thanks
Newbie is watching master
great Mr. Tevz. thanks😄👍
My pleasure!
thanks 👍👍👍
Welcome 👍
Thank you very much, my brother
You are welcome
salamat master tevs👍👍👍
Thanks
No problem

What do you think tevz?
Good boy
It's the glue that assists in the corrosion?
yes
Hi tevvy boy. Do you bother reflashing eeproms in plasma TVs. Have a plasma Samsung boot cycling. Think it's going in the bin
Did not yet tried. I don't encounter that trouble in plasma tv.
Hi engineer
How did you determine the amount of burnt resistance?
Not change the value alot, if the resistor didn't snap, it will still works.
where is your location sir?
