| Philips | FL1.14 | Spoke on 134,25 and 287,25 MHz in proscan sets. | Spoke on above mentioned frequency can be solved by adding two
capacitors of 33pF (5322 122 32072) on the LFR box.
- between pin 10 of H22 and earth (pin 5 of H22) (CVBS).
- between pin 7 of H21 and earth (pin 4 of H21) (TXT INT).
