good morning brother, see if you have 160volt in the filter, then backward everything is fine, that is the AC input, the diode quartet, the rest of the occluders to the filter itself. You need to measure if there is etand by, you can do it by measuring in the EPROM for 8, the same one that you had doubts about what it is. If there is no 5volt then you must continue at the source, check the mosfet and the oscillator, and then measure the cathodes of the diodes after the ferrite transformer voltages, if everything is ok, if you can think of the damaged EPROM. You must reprogram it with the firmware or change the chip.
Rafael thanks for answering, well in the UL41 I have 3.26vy in the eprom on one of its legs 3.20v no 5v ... what else could I check?
change the eprom look for the technical sheet of this and compare it with one that is similar remember one thing when you make the change you have to adjust the TV to factory setting, so that the micro can master it, write it with the firmware, it is ok voltages, this is what should be in the regulator, this according to the configuration varies the voltage, but okay, change the eprom, check if you can the frequency of the quartz that has next to the micro I hope you solve the problem with the tv Anything you write me an email Regards
good afternoon Rafael.! a query, on these televisions is it likely that the microprocessor writes the programming by placing an empty 25q32?
HOLE, HEAR AT THE END THAT IS THE SAME PLATE USED BY RCA EDE 40P, PHILCO, KONKA AND OTHER MODELS, ONLY CHANGES THE FIRMWARE, SO IF YOU HAVE ANOTHER PLATE OF THOSE TV THROUGH THEM WITHOUT PROBLEMS ... ANOTHER ALTERNATIVE FOR YOU TO RESOLVE FAST
I have the memory file for that card, send me the email address to send it to you, since I tried to upload it and I couldn't
send it to me to have it please, I still have to buy the programmer of these memories, if the TV brings a 25q32bvsig winbond can serve without problems placing a true 25q64 ?, my email is: neomatrix92@hotmail.com I have been looking for information and I saw that there are several versions for that TV model L39F6 and that if you place the programming that is not correct the screen can be flipped and that ...
