Repair of an Philips 19pt825b/00 - fl4.26

Post by ElectroGehirn »

Hello Community :)

I need some help with my philips crt, would be nice if someone could go step by step with me to troubleshot the problem my TV has.

I do realy like the TV, it would be cool to get it working again :D

It started with a little tilted image, but i was like, okay i let someone do that, becaus i have my respects on him, opening him for a "little" thing like that was not a reason for risking to open him up
but no there is a reason.

Back story
So i was trying to watch my UHF signal over the air, after some time it made a "poof" like sound, it sounded real muffeld.
After that i got no image anymore, the on/off LED lights up red since then, if i press a button on the remote that would trigger it turning on, he will sometime flash on the left side of the tube, but only if he is not charged anmore,
but that happend nomore since a while. the LED also flashes a ms, but as i said, he will give up on it.
Also i heard while playing on my Xbox a short cracking like noise from the inside when he was still working, it happend like every 20sec i would say

The problem
No image anymore, as soon as i try to turn it gives up immediately.

If someone needs more pictures or picture of a specific part, just ask for more :-)
I would be very thankfull to get him working again.

I also wanted to say that I am handy with soldering iron and skilled enough to replace small components too, as long as i know what i need to replace, im just not good at diagnosing stuff, especially CRTs without help :)

maybe found a solution.
This guy: https://www.youtube.com/watch?v=n2nWpySy4-Y
showed a whide blue cap (better look my desciption is a bit bad)

and i found one (there you can see him in my pics: https://i.imgur.com/sYGGK2V.jpeg), and he is a 680µF 250V cap.
I tested him on my multimeter and it shows on the 200µF setting, 000.6 µF

i would say its broken, but would be happy to see confirmation on that

i also tested an 16V 22µF cap, it showed 26, so i would say normal, checked, okay lets test on the 2µF setting, yes it shows a 1. for too high, so that should have happend on my 200µF setting on the 680µF cap right?
