Are you saying you see tracks (darkened circuit board) on the board? Most likely you have had a bad voltage surge or near by lightning strike that has burned through the circuit board (very high voltage). if you are talking about the screen image, you got me.

Testimonial: "No it's on the image on the wall. It does look like darkened circuit board though, if that helps."

Dgx 230 dc in connector bad


This type of keyboard is well know for the power socket breaking away from the main PCB. You will need to unscrew lots of screws to reveal the circuit board with the power socket on. If you look closely at the solder side you will probably see that the track that the socket is soldered to has broken. Simply link the solder joint to the circuit further along the track by bridging between socket and next point along the track. You may need to replace the socket if it has become damaged. If you can use a soldering iron it is fairly easy but if in doubt contact a repairer.


If you need a socket Google :

No images only the sound


hi,
You have to check the back light of your lcd TV. All lcd screen have a back light to illuminate the pixels. you can conform is the back light is faulty or not by watching the lcd screen nearby. Watch can you see any image (negative image) on the screen. you have to look very closely. if you see any image on the screen then the back light or the back light inverter is faulty.

You have to check the back light inverter board. Normally in lcd monitors you can see three circuit boards. power supply, mother board, and the inverter board. If available then try to replace the inverter board. There are high voltage transformers in this board. There is a chance for its winding get short. You will not get the transformer in open market. Try for the inverter board .
ok

If it's working at all it is unlikely to be the hard drive.
It may be a broken track or connection on the circuit board, but again it's surprising it works at all.
Try resetting it. It is so close to working properly it might work.

Green tint on screen


Is it a green tint at some areas alone, oris the entire image having a green tint? If it is a color patch at the corner or other areas of the screen, in all likelihood it is a degaussing problem. Color patches happen when the TV is moved from one location to another, or if some magnetic source is placed close to a CTV. Did you put a radio or Tape recorder or Walkie talkie toy or any magnetic source near the TV? if yes, remove it. And the automatic Dregaussing circuits in the TV will resolve the problem in a couple of days. But if there is an overall Green tint on the picture, it signifies a problem in the Video output stages, and there is nothing you can do, but call the technician (unless you know solid state servicing?)
