Lcd screen has a contact problem, only works when torqued
Lcd screen has a contact problem, will only work if slightly flexed. Is this usually fixable? When faulty the screen breaks up into horizontal lines and mouse feedback does not work. If you twist the screen it resolves temporarily.

Hi,blank screen is usually caused by bad screen or flex depending on the type of phone you are using at the moment. If the phone is a flex phone that means you will need to check both the screen and the flex.(flex makes the screen to display). When you replace the screen,the phone display will be working again.
This is a common issue to occur to LCD monitors when the LCD panel is faulty, there is trouble with an internal cable that connects the panel to the power source (or inverter) or sometimes the trouble lies with the plastic bezel surrounding the monitor. The plastic bezel is improperly applied or warped in some way due to excessive heat or simply over time and it may be pinching/pressing against the panel cause the screen to flex slightly and cause the lines to appear.
First, in the event that the LCD monitor is under the manufacturer's warranty or another form of coverage - such as an extended warranty - this should qualify for a replacement under warranty coverage.
If it is out of warranty or not covered in anyway, proceed with the steps below:
A. Plastic Bezel Flexing
Check the plastic bezel for flexing, the easiest method is to simply press down softly on the plastic nearest to where the lines are. Press down softly while slowly applying slight pressure on the area. Looking for any signs of the lines disappearing (or getting worse). If the pressure applied to too much, you could crack the underlying liquid crystal display so do take good care to patiently press down on the screen.
B. Internal Component Failure
Internal components such as an LCD cable or inverter board are much cheaper from $3-12 per component.
C. Faulty LCD Panel
In the event that the LCD panel is faulty, the only solution is to replace the faulty LCD panel which will cost from about $65-120 for the replacement part. Some online retailers, like eBay typically have panels for sale by other users at about $20-30 but bare in mind that these units are sold as-is with no warranty what so ever and usually have no guarantees as to if they will work and for how long.
Aside from that, there are some online services that offer repairs of damaged LCD panels. These services can usually be anywhere from $25-70 to correct the panel for a flat fee and warranty their work for 30-90 days, depending on the service provided.
mine started like yours then stopped working at all .It's a flex wire that connecting LCD with camcorder. it's very common. I did by miself, bought it in repair shop. works like new. mine is DCR-SR32 wire is 1-871-457-11 known as 1-871-457-21
You LCD is not making proper contact with the camera board that the flex cable plugs into or you have a bad flex connector. A LCD has 2 part, the actual image and the backlight. All you are getting is the backlight with no image. You camera will have to be repaired to see if reinserting the cable into the flex connector will solve the problem.
This is probably a bent pin in you flex cable to the lcd or a poor connection,you will have to open the phone up at the lcd usually 4 screws around the lcd im not familiar with the model you have but this is a general problem with cell phones,after you get it open you should see the flex cable connected to the lcd disconnect and inspect the connection pins the gold looking metal parts if all look the same plug back in the cable making sure its in good and try it out,if this does not work your flex cable may be worn out and since im not familiar with that model i cant tell you how to repair it,well good luck
your screen dosnt display anything?I am not quite sure what your asking but ill take a crack at it anyway.you changed the housing and when you put the phone back together the lcd stoped working,if this is the case you either disconnected your lcd or you damaged the flex cable to the lcd,either way you need to open your phone back up just the top part where the lcd is,you should beable to see the flex cable coming from the phone to the lcd if it looks connected disconect and reconnect and try it if this does not work you may need a new flex cable wich means that you may have to get a whole new keypad cause the flex cable usually only disconnects from one side,well good luck
