Motsey:
Ahh yes i remember reading that awile ago!
I had an accident, well I was totally stupid - I was testing the power board and plugged it in but it ended up touching something metal and shorted :03: There is a burnt mark there and it wont power on!
Ahhh soo annoyed off with my self - going to have a look at the board closer and see if I can work out which components are damaged and if the board can be brought back to life.
Does anyone know where I could source a replacement power board from? I cant seem to find any in stock anywhere at the moment.
davenjax:
hi mate gutted for ya .have you checked ebay ? .dave
Motsey:
Yes had a look on ebay and no luck - Im going to look at the board in more detail when I get some time this weekend and see if I can revive it x fingers crossed
Motsey:
Was looking at the power board today and noticed a fuse was measuring 0 and thankfully changed the fuse and its back to where it was before my stupid mistake - so now back to flash blue light

I have followed these instruction ;
1. Short out the eeprom pins 5 & 6 ( the two legs with the resistors ).
2. Turn on the power. - Instead of the usual noticeable relay click, you get a faint click, the backlight stays off, nothing else happens.
3. Wait around 1-2 secs ( anything longer than this NEVER seemed to work ).
4. Remove the short
5. Press info,menu,mute, then power - In that order individually, one at a time.
6. TV should come on with noise picture and the service menu.
7. Navigate to reset to go back to factory defaults and you're away....
I have done 1,2,3 & 4 and when I try 5 the tv just keeps flashing
I had it on its back open and was pulling out different leads and testing it and it worked sometimes but if I try it again with that same lead out then it wont work - strange
