Varebeskrivelse
Stand: Skal repareres
Rare Sony GDM-FW900 monitor - widely regarded as one of the finest CRT monitors ever produced. This legendary 24-inch widescreen FD Trinitron display delivers exceptional image quality, deep contrast, vibrant colors, and ultra-smooth motion that still impresses enthusiasts, gamers, and creative professionals today. With support for high resolutions and refresh rates, the FW900 remains a highly sought-after flagship CRT, offering a viewing experience that many modern displays struggle to replicate.
The monitor worked initially(see pictures), but would sometimes refuse to power on. I sent it in for a full diagnostic and re-cap. The flyback was suspected and replaced with a confirmed-working unit—no change. Both 2SK2655 horizontal output transistors have also been replaced with new parts—still no joy.
The exact symptoms, does not power on:

Tube has also been tested and measured OK:
Heater Continuity
H1 <--> H2
= 1.8 Ω (OK) | Expected: Low resistance (≈ 1–10 Ω)
Heater -> Cathode
H1 <--> KR
= ∞ Ω (OK) | Expected: Very high resistance
H1 <--> KG
= ∞ Ω (OK) | Expected: Very high resistance
H1 <--> KB
= ∞ Ω (OK) | Expected: Very high resistance
Cathode -> Cathode
KR <--> KG
= ∞ Ω (OK) | Expected: Very high resistance
KR <--> KB
= ∞ Ω (OK) | Expected: Very high resistance
KG <--> KB
= ∞ Ω (OK) | Expected: Very high resistance
Cathode -> G1 (Control Grid)
KR <--> G1
= ∞ Ω (OK) | Expected: Very high resistance
KG <--> G1
= ∞ Ω (OK) | Expected: Very high resistance
KB <--> G1
= ∞ Ω (OK) | Expected: Very high resistance
Legend:
KR = Red Cathode
KG = Green Cathode
KB = Blue Cathode
G1 = First Control Grid
∞ Ω = Open circuit / no measurable continuity
OK = Measurement is within the expected range.
