Re: Samsung LE37A656A1FXXU dead after service menu

So I finally managed to get TV back into operation by switching into service menu and than blindly pressing randomly buttons ( as I had no picture ) until picture pop up. It was definitely luck, but help. Thanks to all for support.

I tried this procedure on my MT8226 EMMA main board ( I found a IC7004 which I hope is the correct EEPROM) . I did this coulple time, but TV always start normály with the noise on the screeen. Does anyone knows, if the IC7004 is the correct one or what I do wrong?

Thank you.
There are several ICs on board, is there way to locate it easily ? There are also some IC bellow shielding which is soldered. Should I remove it and look under?...

Bingo - The F1 is blown off !! Thank you tom66 and budm for guiding !!
Do you know, what should be the replacement ? Is it common issue, when fuse replacement helps, or there is a reason and there is a deeper problém behind ?

Hello Guys,
I have problém with tv that won't turn on (similar like [url]https://www.badcaps.net/forum/showthread.php?t=35424&highlight=samsung[/url] )
also when I plugged in stdby led is on, but when try to turn it on with remote led blinks five times, than led switch of and TV turns on but there's nothing on screen, neither there is samsung chime nor sound. I can see that set is responding on remote commands because led is blinking when some of keys is applied.
Few months ago I did replace the capacitors in power supply becuse of blinking issue which helps. Now all...
