Re: Engel Led tv problem


Acctualy problem wasn't in bad solder, i bought thermal paste mount transisto on heatsink and boom goes again discharge on transistor, transistor is somehow shorting to ground on sink, no wisible damaged but i isolated litle screw that holds transistor , mount transistor and now it is good.
Thanks for trying to help evryone ...

Re: Engel Led tv problem

Well look's like i solved my problem, tested evrything good and then just decided to resolder evry component around transistor and now it is working

Re: Engel Led tv problem



What should i look for that is discarging those 2 big capacitor on Q4 and blowing fuse . all diodes and transistors are good other components not sure how much should it be on some resistors that are almoust without resistance...

Re: Engel Led tv problem



Didn`t have time to check evrything because i have to go to work, but it seams that it is that board...

Re: Engel Led tv problem



No work on TV , bough it a few years ago i don't even remember how long exactly but around 5years and was working perfectly till now.
I soldered glass fuse same spec as the one before but it is difrent IT WAS SR-5-3.15A-AP and on heatsink transistor is middin because it is desoldered curently ot is SW10N65 transistor....

Started few mounts ago with winter TV not turnig on until i heated it up with my halogen heater, but worked normaly after cold start turn of and on without problem, and now when winter is over it was starting sometimes even without heating till today no start.
Opened it blown fuse and some black burning around this transistor [url]https://ibb.co/cTMkdc[/url] [url]https://ibb.co/eokYWx[/url].
Replaced fuse and as soon as i conected power boom fuse gone and crack from transistor like capacitor discharged on him, i desoldered it and check it with multimeter and he is working fine, check...
