If the problem is not fixed by this then go in the menu option of your television. Check if any of the settings have been changed by you accidentally. If you find that these changes in the settings are the cause of your problem then change these settings. If this doesn’t fix your problem or there are some other problems then try the following techniques.
Fixing screen problems of LCD TV
- If your screen is pink or flashes or the audio system is not working properly then the problem is related with the DDC communication. To fix this problem, power up your system when all the HDMI cables are connected. If this doesn’t work then try using different inputs. If this also fails to fix your problem then install a DDC line condition. This will definitely solve your problem.
- If the picture comes and goes frequently, then either the TMDS channels are getting high bit rate error or not working efficiently or there is a problem with your DDC line. To fix this problem replace your cable with a better quality cable having larger diameter.
- If you see sparkles in the picture then there is a problem in the video data transmission. This may be due to the length or the quality of the cable. The length of your cable should not exceed 10 meters or else it may cause problems. Sometimes bad connectors are also responsible for such kind of problems. Identify the exact problem and either replace the cable or the connectors.
