Need help fixing Samsung Slimfit tx-s2783
Okay. So I noticed that there is wiggliness in the top 1/4th or 1/5th of the screen. It relaxes and gets less wiggly when things warm up. From my research, that's horizontal deflection. So I recapped all the electrolytics. Pretty much any CRT is due for that. The colors and geometry got WAY better afterwards. Not bad for my first CRT recap. But even though everything looks better, the GOD DAMN deflection issue is still there. So I said okay, maybe these big brown film capacitors adjacent to the flyback are on the Fritz. So I remove one. Can't tell what 125j is because I have no electronics knowledge, so I measure the capacitance with my multimeter. Comes out to 1.2uf. okay. About what I would expect from a film capacitor. So I move on to one labeled 644J 400V (the kind of voltage I would expect would have to do with something like deflection). The multimeter read 615 NANOFARADS... What the hell? 615 NANOFARADS!? That's a completely retarded measurement. It should be under 5uf. Is this a sign that the cap is bad? Should I pull others just to see what kind of measurements I get? The first one was fine... There are service manuals for some of these slimfits, but my model has not been posted. In the 30inch service manual i found, there were part replacement details. this is EXACTLY what I need to replace the film caps, but I still don't know if I'm tackling the right thing.
I don't know what I'm doing. I'm extremely overwhelmed. I'm glad the electrolytic recap worked and I didn't fail at that, but these big brown sawhorse film capacitors are ridiculous. I don't even know if it'll fix my deflection problem in the first place. PLEASE help! https://i.postimg.cc/sxvLSMWv/PXL-20...-201041560.jpg https://i.postimg.cc/KjwH5m7Q/PXL-20...-201031317.jpg https://i.postimg.cc/13pjph8c/PXL-20...-194505081.jpg You can see the wiggliness in the screen pic.
