I'm not sure the remotes have a light on them. I thought that was for the D9400's. I just fixed a D9200 and didn't see any light on the remote...
nope no led lights on this remote board
that's correct.
More Tip's with this chassis.
All 9200's that have original caps needs a cap kit
but not all the caps go bad..Its takes about hour and 45 mintues
to install all caps for me.
Not just caps fail on the chassis either there are semiconductors
fail too.
Unless work with the chassis much you should do a cap
kit first and then work from there.
I have a list i find bad every repair and i replace those first
and test the chasiss.
Could also be vertical collapse and when you turn up
the screen control you see a horizontal line
then you will know you have high voltage too.
If you dont see a raster then you wont see a menu..
I replace the eprom when it gets corrupted
at a cost of $2.50 not reinitialize it only to learn i didn't
complete the repair because the chip is bad and needs replacing
And when you reinitialize it it goes to a factory settings'
which are not the correct values!
Still need to readjust advance settings for geometry and RGB
because trap,side pin etc all get changed of coarse if you just want to
guess at it you can but should do it with test patterns, game companys
dont set this up the monitor company preset them with factory test patterns.
the data value are different which is a very common procedure
when dealing with eprom to copy down them first so they can
be reintered back in..Blindly resetting this is not a good idea unless
it needs it then i would just replace the chip then re'enter the data values.
Try copying them down next time and then you'll see they are different
after you blindly reset them.
Very common on tvs that been using eproms for decade's to copy them first!
I find that when the mosfets for different resolutions are bad
that the driver circuits can't lock in and part of trouble shooting
could be to find a resolution that works will give you and idea whats happening too.
The mosfets would be mostly likely because they are high current switching parts
and more likely to fail.. and of coarse if you found a defective mosfet then
you just wasted the time resetting the eprom and now added more adjustments
to the repair..to each thier own as they say..just dont add problems..
I think your'll just adding problems by doing the reset unless its needed
need to replace the chip then adjust to correct values.
From my experience with eprom you can get the values and re-enter them
for the best picture. and bring it back to the correct picture.
I see it as a EPROM 24c02 not a CMOS which is different component.
