Progressive Scan Related Questions
Progressive Scan is a system of displaying image in which each line is scanned in a sequential manner, unlike the interlaced scan used in traditional television formats. This format is used in most televisions, video projectors, computer monitors and so on whose display resolutions are progressive by nature. Both the display and the source need to be compatible with the progressive scan format in order to access the scanning system. Below are frequent asked questions on issues relating to Progressive Scan that has been answered by the Experts.
How can I turn off the progressive scan mode on my Goldstar VCR/DVD player?
In this particular case, you would need to perform a reset on your DVD player to get it out of the progressive scan mode. You would have to follow few steps in order to do that. The first thing you would need to do is eject any disc that is there inside the unit and then close the disc tray. You must ensure that there should be no disc being displayed on the display window. Now once that is confirmed, you would need to press the Stop button and hold it for more than five to ten seconds. After that, you can release the button. Now this procedure would allow the video output to restore to the standard setting. Following that, you should be able to view the picture on a conventional analog TV once again.
When I insert a disc into my DVD player, I keep getting the ’wrong disc’ message. It is a Memorex DVD Progressive Scan player. However, the disc plays fine on other players. What is the problem here?
In order to cure this issue, the first thing that you could do is use a CD/DVD laser lens cleaning disc. You should be able to get it from most electronic shops. To begin with, you would first need to insert the disc and then allow it to run for few minutes inside the unit. This would clear the dust and dirt from the laser pick up. Now this procedure might entirely cure this problem. However, if you see that the problem still exists even after the cleaning is done, it would mean that the fault is with the laser inside the unit, which has failed. These kinds of failure could be a manufacturing defect sometimes. Therefore, in a case like this, you would have two possible options. You could fix the unit yourself by purchasing the required parts if you are efficient with electronic repairs. Or you could take the unit to a local electronics repair shop and have them deal with it. However, it is always best to have a specialist repair the unit, in case you are not completely sure about this repair. You may cause further damage to the unit.
The progressive scan of my Magnavox Projection HDTV went blank. When I tried to turn it on, the light in front flashed but it did not blink. There is also a chirping sound in the rear. What is the issue and how to fix it?
In this kind of a scenario, there could be several reasons that may have caused this problem. The most common of all is the convergence circuit failure. These kinds of circuits usually line up all the colors on the screen. However, when there is a short circuit, it tends to shut the TV down in an exact manner like yours. Moreover, it is common for this circuit to go faulty a year after its replacement, if the job was not done properly at that time. Repairing this circuit would usually cost you around four hundred dollars. However, apart from the convergence circuit, there could be many other possible reasons that can cause this problem to occur. These reasons could be horizontal circuit failure, deflection board or main board issue, fluid leakage and high voltage circuit problem to name a few. On an average, you could expect a repair cost around four hundred to seven hundred dollars depending on the type of problem. Now in order to determine the exact cause of this problem you would need to troubleshoot. For that you would require a multimeter, some knowledge about electronics and good soldering skills. In case you have none of these, the best thing you could do is have a repairman fix this problem for you.
Progressive Scanning is also termed as non-interlaced scanning. Such scanning formats are supported by most HDTV’s and DVD’s. With progressive scan, the images have become clearer, smoother and easier on the eyes to watch. However, it requires a higher bandwidth to operate as compared to interlaced scanning. If you need clarification about your specific situation with respect to issues related to Progressive Scan, you may ask a TV Technician expert to evaluate your case details and provide a technical insight.
