Question about Philips 50PL9126D/37B 50" DLP TV
Must start from the front end of the set.
1.Check power supply to the main board if absent then check the SMPS. ( please check my tips column in my profile for SMPS repair tips)
2. If power comes to the main board look for visible areas of component damage . If not the convegence section is faulty.
Check by swapping with a board.
3. If the TV has power and screen then check the signal,the input processing section. Switch inputs to confirm.
