PHILCO TP2054
TV with super expanded image, replaced wide capacitor, but defect persisted, it also contained a vertical, transparent list, the thickness of an index finger on the right end, the globe symbol only appeared as a dot due to the expanded image All voltages ok, after a lot of analysis, I based it on the schematic, I saw that tsound was an SMD capacitor on the c722 position board, tsound wasn't one on the schematic, so I removed it, and I hugged it, thank God, good luck ..

Calls and writes philco and erases the philco logo and nothing else works, neither the remote nor the keyboard. In my case I updated via pen drive and it accepted the update, tsound was that blue screen of updating up to 100% but it stayed the same. I noticed that sometimes after the logo was erased, tsound would be interference vertically and sometimes it didn't happen at all. I suspected the data clock line, but before seeing that, I remembered the reset and when I changed the capacitor c536 on the underside of the board the equipment started working again, as tsound is the reset circuit, I also resoldered it and cleaned it afterwards. So how did you solve it and I believe that in my case it was that. Check reset circuit c556, n515, both underside of the board. Because as we know, the Philco logo is in the room and not in the firmware, which is why the update did not solve the problem. somehow after the logo occurred, the equipment would have to start reading the firmware memory and it didn't happen, so I thought about data clock, but maybe the reset somehow didn't happen perfectly and this prevented the correct initialization or command lines of memory.

Darkening the screen. in a few minutes it becomes very dark. Q513, q523, q533 (all bf423) on the kinescope board. It's usually the bf422 that cause the most problems, but that wasn't my case. R-Tec

PHILCO PH24A LCD
When you turn on the TV, the red LED stays on but when you press the power button it doesn't turn red and it doesn't work. On the main board tsound are 2 cis 3.3v regulators. one of them is not regulating the 3.3v. tsound will be less. good luck! João Carlos eletronica- Paulista- pe
