come on guys someone must has some idea please :thumbup:

daz:
sets with the same model no and av pcbs often use different screens, are you sure both sets had the same screen in them ?

snopy44:
dont know was told from were i got it from that is a well known place that sells parts mensioning no names that it would work and apart from the wide sreen mode it dose i have look over it with a magnifi glass and all the parts are the same on the board and nothing looks diffrent just dont want to keep spending money i dont have to i know i may be to fussy as the board i got from my friend that works but has only an anolog tuner just want the tv to work the way it should :wallbash:

daz:
ok, there are two options, the board you have is duff or the software needs to be changed to match this screen. to check this you will need to find out what chassis the set is, this is printed on the label on the back of the set, i THINK its a lc7.2 ,below is an address for the service manual, first easy thing to check is the option codes (printed on the same label) enter the service mode and confirm they are the same,if this dosnt fix the problem you then have to compare parrameters are the same on both board, you will have to refit the old pcb and note all the parameters,this is going to take some time.
the service manual will be a great help,read it first, be warned if you make adjustments that are incorrect you may make the fault worse,
good luck

ps its always possible there was a problem with the software on your old pcb

daz:
just noticed the audio amp ic used on the lc7.2 chassis is also used on many a vestel chassis to which they cause lots of problems, perhaps this is the cause of the original fault, now you have two pcbs you could try swopping them.
