Question about Philips 37PF7320A 37 in. HD-Ready LCD Television
The best that can be done by you:
1. check the battery , replace if bad, check the battery terminal too, if bad clean.
2. Remove the covers, use a good soldering iron to solder the crystal and the processor in the board, use a thin needle to clean the pins after soldering to ensure that there is no bridging in the circuit.
3.use a dry wipe to clean the surface of the board. check if the IR Leds are working or out of circit, if so replace.
4. The transistors switching the IR should be checked.
5. If carbon pads are bad replace with spare dots available or use a carbon pen to line.
use a multimeter to check if the IR works ,if not the IC can be faulty
If none of the top works youmight have to cchange the IC .
Hope the advice helps.
