TV Repair Questions? Ask a TV Technician
Hello. Please BE aware This is tech information service. you are paying for the benefit of my real world experience and can save you time and money
the LCD DISPLAY is bad
I have seen it a number of times
there is nothing you can do
time for a new tv
this is not repairable
the cost of a new lcd will exceed the cost of a new tv by 2x
your best bet is to SELL the boards on EBAY to recover your investment
I am a tech, that is correct for the common person, I am cert in LG, Sony, Vizio but I am stumped, I know this can be repaired by opening up the display. One of my customers asked me to cart it off when I said the same thing. So I have said that, do you know anything about Panels?
if you open the panal there are 2 boards fed by the tcon
one is responsible for each side of the screen
there are NO parts you can service on these boards
the only i have doone in the past
is removed square capacitors that shorted out
killing the supply to that section of the board
its a long shot
another tech told me the same thing, also about a resistor, so you are saying they are surface mount on these boards?
and the panal itself is laminated connections
so you have to realy be careful with heat
i have removed shorted caps before and plugged it in it worked
I am ISO9001 cert on surface mount so what do you think, could I possible do this?
i buttoned it up and thanked the gods!!
the caps on the board under the LCD, this is what we are talking about
there is no tech data so you have to fly by the seat of your pants
as long as the owner understands this is a long shot
the panal could wind up WORSE than it is now
yep I understand there is no data,
not that it matters
I am hte owner
but i shy away from these jobs for that reason
I might fix it
I might make it worse
as long as you understand you have nothing to loose
than go for it
OK so to recap the problems lies on the flat ribbon cable going from the Tcon to this board on the back of the LCD
unscrew the metal case on the screen and carefully remove it
or on the board or both
sometimes the ribbon will burn!
because of the short
I verified whitch side is bac already by removing one cable at a time from the Tcon to the panel, it is the smaller one if that matters
fix the short might need a new ribbon
ok use your meter an ohm the caps
ok you have given me enough info to take a stab at it.
should not read to ground
i have done it
thanks again any thing else?
