Hi all,
I see in various Sony documentation a term called "special PAL signal" or "Ant Pal signal". It is used to calibrate the color decoder. The signal is supposed to be available from a signal generator (exact model never referenced).
I have a Leader 404 PAL pattern generator. While not the most complicated, it is one of the industry standard machine. Also I don't remember seeing a fuction like special-pal in more expensive generators.
Can someone explain what this signal is, and what generator is known to produce this signal? Thanks!
Attached are waveforms and description shown in service manuals, from PVM9220 and 1440 respectively.

Javítható-e ez a hiba?
Sziasztok!
A fenti TFT monitorba keresem az alábbi alkatrészeket:
BIT3109 PWM controller SMD 16 lábú (1db)
AP4502 Dual N+P MOSFET SMD 8 lábú(4db)
A Sinitől rendelhető, de nem ér annyit az egész monitor. Ha tudna valaki reális áron beszerzési forrást, vagy beszerezhető helyettesítőket akkor kérem segítsen.
Most olvasom egy korábbi fórumba, hogy az Si4539DY jó az AP4502 helytt és olcsó is. Az IC-t még mindig keresem.
Üdv.,
Edmundson
