Failed epprom probably usual fault on this model failed caps corrupt the epprom. Try turning the tv off then press info, menu, mute then power and see if the service menu comes up. If so reset the tv.

Re: Samsung LE37r88bd

1) find epprom on bottom of main board (ic1803)

2) take 2 lengths of wire and solder one end of each of the pins 5+6

3) strip the other ends and make sure they are long enough to pass outside the board when main board is re-fitted...

4) plug all connections back in

5) hold the 2 bare ends together so when you let go they will full apart " make sure they dont short anywhere when they separate..

6) whilst holding bare ends together plug in mains supply count to 2 secs and release leads

7) press info/menu/mute/power if tv doesnt come on normally

you may have to repeat the process several times dont give up!
worse case you will need to by a new chip £2 off ebay i think

Hi,I have read about this,is it safe ? Do you have to solder the wire,is soldering the only way will it blow anything caps etc ? Like a second view

Re: Samsung LE37r88bd

So when you solder the wire to pin 5/6 is it a permanent fix or do you have to desolder the wires.

Re: Samsung LE37r88bd

You would remove the wires afterwards, if the fix worked.

As far as I know, the idea is that you interrupt communication to the NVRAM\Settings EEPROM so when the TV starts it thinks the EEPROM is not there, and starts up with default settings. When you shutdown and restart normally after that, it writes those default settings to the EEPROM, thus overwriting any corrupt data, and allowing the TV to start normally.
