diodes (D30, D31, D32, D33); these often fail and can be upgraded to for better reliability. Chopper MOSFET (Q1) : Common parts include MMD70R600P IPD70R600P . A short here usually blows the main fuse. LED Driver (U5) : If you have sound but no image, check , and diode 3. Troubleshooting Common Faults Dead (No Power) : Check for a shorted
To find the , you should look for the specific revision number (like R2 or R4) printed on your board, as layouts vary between models .
