SyncMaster 800TFT

5-2 No Video

Check signal cable and connection.

Check TFT-LCD panel and Inverter.

Check IC201 and related circuit.

Does the outpus signal appear at RA403 and
R411 of IC406? (LDTGB, LVSYNCB, LHSYNCB,
LCKBB)

Is the output of Pins 1, 17 of IC501 High ?

Yes

Does the analog video signal appear at R211,

R212, R215? (BLUE, GREEN, RED)

(IC201)

Yes

Check IC201, IC206 and related

circuit.

Does the sync signal appear

at the output of Pin 14 of IC201and Pin 3 of IC 206 ?

(V-SYNC, H*V SYNC)

Yes

Check the related circuit for these

ports.

Check IC501 and related circuit.

Check IC 300 and related circuit.

Does the input signal appear at the Pins 40, 41

of IC 300?

(PLL H*V MX-PDEN)

Yes

During power on-off does the input signal

appear at the Pin 29,30 of IC300?

(AD-SDA, AD-SCL)

Do the clock and sync signal appear at Pin
115, 117 of IC 300?

(DCLKAB, MX_HSYNC) and does the digital video

signal appear at thr output port PDA, PDB)?

Yes

During power on-off dose the input signal

appear at the R 407 and R 408 ?

(MX-SDA, MX-SCL)

Yes

Check IC 406 and related circuit.

Yes

Check IC501 and related circuit
