So far no la. I have offered to someone but he did not response, yet. However, i usually buy the faulty ones,,

Are you having problem with yours? What model & what is the exact problem with it?.
sync master 193t. there was some peeling on the lcd panel, then i try to remove it and it came out as a whole piece of stick on film. after removing it and puting it back into the case , the image on the lcd screen became very faint.

can still see the image but do background light or brightness set to very low. not sure it related to the film or i accidentally spolit the internal pcb.

any idea?

hi bro.. sorry ah.. i abit confused.. u mean u disassemble the whole panel & remove the peeling?.. or u mean u just pluck out the peel part from the front part of the panel without assembly?. i cannot see how removing the peel-off can effect the PCB..

it can be peel off without taking off the assembly, but i took out the assembly and peel it off anyway. after putting it back, it became the faint problem.

any idea?

Honestly, not really sure what is causing the faint image. my guess is if the faint problem only at the peel off portion then maybe is due to the peeling.. if across the whole panel then could be something else...

quite sure it is deal of something else. the faint image is across the panel. suspect that might have damage some flexible circuit connector when i open the panel up.

i got LCD monitor problem too ...
TS, hope you dun mind me borrowing your thread ...
else, i will edit and post a separate one

brand : HP
model : w2207h
2 inputs connected, VGA from PC, and HDMI from SH HD stb
problem encountered some time back ... once pulled VGA cable from LCD, screen goes blank ... and after a long while (no fixed time) ... screen comes back on (on its own)

so i figured a workaround ...
connect HDMI source from SH stb ...
that way, the monitor has no chance of blanking out since it will auto output ...

unfortunately, i accidentally unplugged both inputs as i was changing stb and pc ...
been close to 3 days, and still blank screen

curious to know what is the cause of this symptom ...
replacement most likely is Dell U2312 ...but no have hdmi input ... meaning i either have to go : hdmi-dvi, pc vga ... dun think will use display port cos i think hdmi-dp more ex rite ?

is the power led light stable when it happens? Plug everything back and shine a torchlight on the blank panel and see whether u can see your pc wallpaper or signal from the sh stb..

Yup. u will need to pry open like a durian. haha. there are a few videos in youtube that shows u how to do it. Initially will be tough, esp on your fingers, but after a while u get used to it. U can use a butter knife, guitar picks to assist u.

Hi, I have got 1 HP 1702 LCD monitor that it's LED doesnt light up.
So I suspect it's the power supply faulty.
I opened and find that no bulging capacitors.

Could someone tell me where has gone wrong?
