I have a Samsung LN46A550P3FXZA 46 inch LCD TV. Screen shows a cloth-like image until the picture arrives on the third cycle. Capacitors appear fine, no doming on top
Bad capacitor.
My Samsung TV ln46b750u1fxva takes a while to power up the light blinks and then comes back on
If you have replace the caps on the main ps board, then you may need to replace a cap on the controller board…and possibly a chip. For me, it turned out that all I had to do was resolder the 47uf cap. I think over time the joints got “cold” and increase the ESR of the cap. While I bought a kit with the chip and caps, I did not have to use them…just resolder. Find the MP2363 8-pin chip on the controller board…the cap is next to it.
