Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent. Line faults to all LCD screen are similar, irrespective of its brand and screen size.
your answer to this problem is easy. First take the batteries out of the camera, then open the camera ( screws should be in the back) the screen should just pop out of the cover and there is a ribbon cable that connects the screen to the circut board. Gently un-hook that ribbon where it plugs in to the board there might be a slid lock to hold the ribbon in place, it should unlock when you pull the cable out (memorize what position the ribbon is before unplugging). Now the fun part, do the same thing to the other camera, (carefully). To install the new screen, plug the ribbon back into the slot and it should be snug, if not there is a lock on it, gently push it back away from the ribbon ( a little finger pressure). Now, simply put it back together the same exact way you took it apart and don't forget the batteries. Have fun taking pictures...
White screen with good audio. before buying pcbs & such. try my repair method.. you need to get the lcd unit off the facia & then remove the front lcd metal frame. at the top of the screen you have 2 thin pcbs - chances are that the ribbon cable got at least one track unbonded. first off put some double sided tape under the pcbs to stick then to the frame - that'll take the bend out of those pcbs !! next put cellotape over the ribbon cables. i then cut 6 pieces of sponge 15mm thick & wide as the ribbon cable & glue to the tape on the ribbon at what would be the top edge of the screen (covering the point where ribbon meets pcb).. put the metal frame on top edge first to keep the sponge straight !! put it back together & fire it up. if it still aint working you may need a tcon pcb (little square one at the top). this fixed my 42lg3000 but can work on others with same fault !!
I would check the ribbon cable that connects the LCD remove from connector and reconnect. The connector, ribbon cable or the points it connects to the LCD panel itself could be bad. The only way to really be sure is to install the LCD panel in a working TV and see if it works. I have purchased TV's with cracked screens (that powered on) ebay fairly cheap for this purpose a couple time's and it has worked out well.
The Dualphone 3088 LCD screen has a terrible habit of coming loose from
the ribbon connector socket on the main board. If you take the phone
apart, carefully remove the LCD screen from the plastic surround it is
in and you will see the ribbon and its board connector. The phone will have a black screen if the connector has come out completely or at least the power pins are out or you will get wierd colors, loss of colors etc if the cable is partially disconnected.
clips on either side of the connector have a habit of coming loose,
freeing the LCD screen. Carefully put the ribbon cable from the LCD
screen back into the connector, you will need to press both clips on the
connector at the same time to lock it in place. (yes its fiddly and I
have to do it all the damn time)
something is pulling down the power suppy and not letting it come up. if you feel confident and know electrical safety, remove the back panel and find the furthest ribbon cable inside going to the board on the left. there are 3 boards at the bottom of the tv, the one on the left is a mother board with many daugher boards plugged into it and standing up. there are 3 ribbon cables that send power from the middle board to the left board. the back most one (front of tv) the one furthest in, under the tubes, is the convergence power. usually if you pull this cable and then plug it in, it will come on and the picuture will be all bowed and distorted. this is a shorted convergence chip, usually a stk392-120 replace both of them and any burnt up resistors to solve your problem this is a tricky repair, let me know if you need further assistance typical cost is 150 to 350 $
Remove the batery. Remove the case screws and pull the case apart. Where the flat ribbon cables connect to the main board, carefully release the clamps on the board end plugs. The plugs don't come off, the ribbon just comes out of them. Carefully remove the screen. It has double stick foam in a few spots. Put the new screen in, reconnect the ribbon cables and put the case back together. 30 minutes max.
