Philips 32PFL3403/12 (także jeśli na pocz. jest symbol 37 lub 42) chassis LC8.1E LB. Main opisany jako 3139 123 6424 1V3 WK819.3.
Jest to jak pisza bardzo nieudany wyrob firmy Ph (robiny w Pl i na Węgrzech) na procku TDA15471HV/N1C00 (wsad MH41886.1.)

Problem z pilotami (na SF173AXG ) i sterowaniem ( co dziwne pasuje od starych Ph na chassis Q522.2 ELA)
Na jednym z forumów opisano to jako brak produkcyjny
Cytat: w pracującym dobrze pilocie opornik 33k wmontowano w poz.R4, w tych wadliwych na poz. R3
Podobnież najnowsza wer. wsadu dla SSB załatwia sprawę.
Co prawda PH wywinął się jak zwykle w biuetynie zwalając winę na innych
Cytat: 29-JAN-'09: Sharp IR-receiver alternative removed as its pinning was not compatible and this component was not verified in Philips STBs. IRIS code added.
By nature, LCD panels based on EEFL & CCFL lamp backlight technology, send out infrared (IR) noise. The biggest radiation level is in cold condition but it diminishes during warming up. However, there is always a remainder of IR radiation.
Some peripheral devices (we see this mainly with Set Top Boxes) use IR receivers which are broad banded. They pick up the infrared radiation generated by the display. In this way the used IR codes of the Remote Control will get lost in the noise.
Peripheral devices with small banded, better quality, IR receivers do not have this issue.
CURE:
Possible actions which can be done to reduce or eliminate the IR disturbance are (for detailed information, see attachment):
- Reduce IR reflections.
- Reduce IR radiation.
- Make use of an IR shooter or extender.
- Replace the IR receiver (*) in the peripheral device (only for Philips devices).
REMARKS:
- (*) The mentioned IR receiver is commonly available in the regular market. Possible types to use are: Vishay TSOP34336 or Vishay TSOP34436. See also attached data sheets for the specifications.
- (*) Be aware of possible warranty consequences when opening these STB devices!
