Basically the UOC is equipped with RGB or YUV input from external, so it is possible to use the DVD input. Selection of these inputs can be done internally within the IC.  But in the G7 and G7A chassis input YUV signal is not used, so in the ground. RGB signal processing flow is described according to the image below : Diagram of the formation RGB signal 1. Signal Yint, uint, and Vint is derived from a series of color decoder and Y / C switch is fed into a series of YUV selector 1. 2. From YUV selector, sub-carrier signal color (U and V) is inserted into the chain matrix. In this matrix series component sub-carrier signal BY of the color (U signal) and BY component of sub-carrier signal color (V signal) in separate. Here the color difference signal in the form of the color sub carrier. GY signal generated by a combination of color difference signals RY and BY. 3. From YUV selector, luminan signal is passed to a series of black stretch. The working principle is to sharpen the series...

Tv tuner serves as the catcher signals from the antenna. Damage tuner, among others: 1. Image does not exist and there is no sound, raster speckled thick. 2. No picture no sound, or otherwise. 3. Channel switching the channel itself. 4. Image blocking white or blue. How to check the tuner and the IF is to remove the tuner from the PCB and connected by cable to the IF path, BM and Ground, then prepared using the pin on the tuner. Then the television was turned on, the antenna is connected to the antenna socket, and RV or potensio rotated slowly to choose the television channel when the tuner is in normal condition, the signal from the antenna to be acceptable, the picture and sound, and the channels do not move themselves. To damage its own channel switch and checked the normal manner stated above, the location of damage on the section of the program.

Removing and replacing the saddles on a Tune-O-Matic (TOM) bridge can be a confusing and somewhat fiddly process, but really isn’t that difficult. Note, though, that there have been several variations of the TOM bridge, and the process differs slightly from model to model. Also important to note is that each different bridge requires a different set of Graph Tech saddles, so make sure you buy the right ones. Go here to check which model you need: http://www.graphtech.com/products.html?SubCategoryID=34 Here’s the patient. It’s a 1993 Gibson Les Paul Studio. If you look closely, you can see that the strings have started to make their own slots where they shouldn’t, though that's not the only reason for this upgrade. The bridge in question is a Nashville pre-2000 bridge, which means the required Graph Tech saddles are part number PS-8500-00. Once the strings are removed, the bridge lifts off very easily. In fact, be careful it doesn’t fall off when you aren’t paying attention (same go...
