Fake HP mon blank white screen

[uligli]

I bought a fake 22' HP monitor a year ago, yesterday i decided to open it to see if it needs a recap, unfortunately i broke the connector of the controller board to the lcd panel, i tried to power on the monitor (holding the connector by hand), now all i get is blank white screen, can someone tell me plz is it fixable?

LCD panel is a CHIMEI M220Z1, controller board and psu full of crappy Su'scon caps

Can't tell from your pictures exactly how the connector broke off from the PCB.

Can you post a differnt view?

I suppose you can cut off the connector and hard wire all the wires to the panel's PCB... that's a lot of work.

They are not fake (well, initially ....).They are the OEM version Tatung manufacture for them.Some of the units are sold as non-HP (no badges), and some people just get the badge from another HP, or some of them even have the HP logo/model on the front,just covered by a sticker.They are basically the same as an HP Branded unit,except they cost about half the price or even less sometimes.I've seen lots of them, mostly F1703,F1503 or v19 models. It was even more common on the CRT models for the Pavilion series..... it is a very common scenario at the USA-Mexico border, in Mexicali or Tijuana. The more obvious place you can see the fact that it is an OEM version is the back label : it won't say HP anywhere ....but still, it is an HP.even the menus (like in this case) say that.

I was wondering about that when I first saw the pics. I thought, geez the logic board look identical to the HP monitor I'm using right now. Same chipset, same layout!

My unit is full of the su'scon as well and I was super careful when taking this LCD apart. The cable is super fragile.

I agree. They are like that, even the HP-branded-all-over-the-place-original-super-expensive units.

It could also have broken due to poor soldering on the the 2 ground shroud points (which also reinforced the port) when the cable was pulled out all of the stress was on the individual contacts.

It kind of looks like the connector can be reinserted into the black plastic piece on the PCB and the ground shroud could be resoldered (to hold the second piece in place) to make the connector work again.

If that isn't possible because the connector is broken read on.

If you are comfortable with SMD rework this can be repaired. You're looking at a 30 pin connector with 27 contacts used.

Get some Chip Quik and remove the remainder of the old connector from the PCB. After the connectors off suck up any old solder on the board with braid.

Then carefully take note of the wire order and the proper orientation of the connector then you'll have to snip all the wires off the connector from the mainboard, strip them, and manually solder each wire to each trace on the LCD driver board. Make sure you verify wire order and connector orientation BEFORE cutting.

Welcome to the world of electronics where a 2 second mistake causes you hours of mind numbing fun .

Re: Fake HP mon blank white screen

Yea, you could also try to find a new connector if the old one is broken, this Youtube video has great info on soldering SMD components with small leg spacing;

Re: Fake HP mon blank white screen

I'll try to solder the tiny wires with the pins of the port, may take me long long time cause i don't have any experince soldering smd componets. Also will really appreciated if someone tell me where can i buy online that tiny port or whatever is called.

Re: Fake HP mon blank white screen

Both options will take about the same amount of time.

While I have seen that same female connector on many HP/Benq builds I've never broken one. Since I always disconnected the cable from the video main board end since that connector is more rigid.
