BRUHM LED TV REPAIR

This 32″ led TV was brought to me by a neighbour with complaint of self increasing and decreasing volume after liquid deodorant accidentally poured into it by his wife. When I plug TV to wall socket, standby led on, and when I powered it, ( press on/off button) it on, but the standby and on/off LEDs On at the same time, blinking simultaneously with volume increasing and decreasing by itself.

Even at OSD mode it was abnormal: all OSD functions moving to the right continuously. Picture below.

So I just pack it in the store, hoping to replace the one single board TV is having. After about three months in the store, I read Mr Parasuraman.S article repair on similar TV (article 945 of 21/01/22) explaining how he changed all e-caps on the board. So I decided to try same on this particular TV also.

So brought TV out, tested it first by powering it, to my surprise it worked again even for longer hours. I guess TV must have dried very well over the three mouths in the store. However I still went on to replace some of the e-caps with new ones.

To my surprise while I was trying to desolder out one of the e-caps, the negative pin just pull out from inside of the cap, perhaps it’s one of the problems affecting TV.



Then I tested TV for about 11 hrs and it worked perfectly. Customer has picked TV for about one week now with no complaint. The pictures are below. This is the finished repaired work :

    Well done! It is incumbent on every technician not only to restore the set but also carry out essential preventive maintenance. Reliability will improve our reputation and publicity will then be from mouth to mouth! Many thanks for your comments!

    Repairs that are about moisture damaged boards are always taking more time than usual. Good thing that you didn't give up on this tv after 3 long months!

    It would seem what you have done is the very essential purpose of these repair articles. I will admit to it myself, having read several items that I later used to repair things. Thanks for sharing and keep up the great work!

    A customer waiting for three months for the technician to fix his TV is really impressive. It's a rare trait. I can't imagine a customer from my country can do this. Perhaps he will accuse the technician of having damaged his TV and his file a lawsuit against him.successful repair thanks to such a well exploited coincidence with the article by Mr Parasuraman.

    Good Fix! Some time Capacitors physically look in good condition but under load it fails.

      Capacitors are usually a problem best is to have a capacitor tester which will show the actual condition of the component
