So i guess you perform and pin 5 6 connection process when you might think the eeprom is corrupt or way off the factory settings ?

Re: Samsung 40 inch LE40A456C2D No HDMI picture - with pics
Ok I'll order a replacement board, prob around £25 with postage.
I agree its prob shoot.
But,
can i ask, from a learning point of view... the eeprom pin connection process, is that very much the same as doing a service menu 'reset' ???Leave a comment:

thanks Tom -
Press INFO when on HDMI. Does HDMI1 appear again? Yes info about the source displays, 1980 x 1020 24hz etc.
Does menu work on HDMI mode? Yes the menu displays.
After selecting HDMI can you select other ports too? Yes
Have you tried other HDMI ports? Yep there are 3 hdmi's and its the same results for each.
Have just been in the service menu again. I notice it has a menu 'WBA Adjust' then 'Calibration', then 'HDMI Calibration', this has 'Failed'...Leave a comment:

Samsung LE40A456C2D
Hi picked up a Samsung 40 inch LCD TV.
When i first got it , it had a blown power board fuse
and swollen caps. I replaced 4 caps and the fuse
and re-inserted the board. The fuse then literally vapourised with a bang.
I then removed that board as it must have a nasty short.
Anyhow, ordered another psu off ebay and got it going again.
Checked voltages too, all seem ok.
Latest aggrovation is the TV does not show any picture
when an HDMI source is input, but DOES work ok with
a SCART input, both video and audio.
