DC-coupled AC coupling. When the capacitor capacity between 0.01μF ~ 0.47μF selected by experiment , the capacity is too large, there will still be some degree of black ; capacity over an hour, on-screen characters are incomplete or relatively dim. After I turn this circuit has : TCL ace 25 × × series PCA84C641 {25} feet on the LA7685 {30} feet , Merlot M2188 's CTV222S. PRC1 {25} feet on TA8759BN {53} and foot . After some TV as simple to capacitive coupling , the effect is not very good , the experiment also need to have some DC component , then the string must be in parallel with the resistor and capacitor and then to the circuit, such as Venus C6430 series PCA84C844P century style , etc. / 256 { 25} feet on the OM8361 {21} feet.VLMservice manual download site

Furi century, when the window of 29S Series S4 movement improved , encountered the following special circumstances : when the I001 {39} feet and I201 (TDA8362) {21} to the capacitive coupling between the legs , and a signal is normal screen characters no black screen phenomenon, but in the absence of signal or AV status , no blue background , no on-screen characters.
