Problem A fixed screen can cause permanent damage to the TV Braun tube. Descriptions Braun, PDP and LCD TVs can all be damaged. When a still image is displayed in a sequence, this can leave stains or after-images due to the characteristics of the panel. However, the DLP TV has the advantage that no stains or after-images are left on the screen. The DLP TV has mirror pixels on the DMD panel that project the beam onto the screen, in which the mirror is a digital representation of 0s and 1s, leaving no trace of light. The mirror returns to a blank state so that no stains or after-images are left. The SAMSUNG SKY500N model has both an ANYNET port and a SERVICE jack port. Because the shape of the ANYNET port on the DLP TV is the same as that of the SERVICE jack port of the SKY500N, it fails to turn the TV off after a connection has been reported. The ANYNET port uses an RS232 port called Phone Jack, | | HTL5076SX-XAA_13.pdf | | Troubleshooting

Main Board
The DLP TV is largely divided into: Power part, Engine part and Main + Rear parts. The ass'y that consists of the DMD board, Detect (Actuator) board, lamp, ballast and optical devices is called the Engine. The main + rear board parts receive the AV signals to output voice signals and process the remote control signals. The engine part displays the video data on the screen, which is generated in the main + rear boards. The AV signals are input through the main and rear boards. CXD3815 processes the MUX and decoding while S5H2201 processes the CPU functions, MPEG and I2S. Finally, the improved DNle image is sent to the DMD engine board. The final data by DNle is processed in DDP3021 of the DMD board to display the image on the DMD panel. This image is created by the light of the lamp through the color wheel which is enlarged and projected onto the screen. Thi | | HTL5076SX-XAA_5.pdf | | Electrical Part List

1. Precaution
To avoid possible damages or electric shocks or exposure to radiation, follow the instructions below with regard to safety, installation, service and ESD.
1-1 Safety Precautions
1. Make sure all protective devices are properly installed including non-metallic handles and compartment covers when installing or re-installing the chassis or chassis assemblies. Make sure that no gaps exist between the cabinets for children to insert their fingers in to prevent children from receiving electric shocks. 6. Errors may occur when the resistance is below 1.0 or over 5.2 . In these cases, make sure that the device is repaired before sending it back to the customer. 3. Check for Electricity Leakage (Figure 1-1) Warning: Do not use an insulated transformer for checking the leakage. Use only those current leakage testers or mirroring systems that comply with ANSIC 101.1 and the Underwriter Laboratory's specifications (UL1410, 59.7). 5. Warning for Engineering Changes: Neve |
