I have a JVC (Amtran) EM48FTR that is starting to take a while for the picture to show after turning on the set.
The unit seems to power on fine and normal with sound and ability to change channels, inputs etc. but no immediate picture. After a few minutes there might be a flash or two of a garbled line and it shows image and looks great. The delay of image seems to be getting longer and longer.
I opened up the back and the caps on power supply and main board look fine. The power supply has some Sam yeong and a rubycon while the main board has a mix of TK and Jamicon.
Main board replacements oh Shop Jimmy look to be hard to find but they did pop up with the eprom chip replacement as a common fix.
My question: is there a known defect in those eproms that requires replacement or are there bad caps or other components on the board that are damaging the eprom?
2nd question is if I buy the shop jimmy eprom will it be pre flashed with the correct software or is that something I would have to do after replacement? I have scoured the web for firmware for that TV and come up empty.
Any other advice in getting this TV back up and running well would be greatl appreciated.
Thanks
