What is SCALER?
Ⅰ. Understanding of LCD TV
- CRT can display any resolution picture without conversion but LCD and PDP can do only with scaler- Accepting input images from multiple sources and displaying them on any flat panel display- Scaler is most important IC in flat panel display
Scaler
1. RF(Radio Frequency) - 50~900Mz Frequency Domain - Composite signal+sound signal2. CVBS(Usually AV) - Composite video and sound signal3. Super VHS - Separate Y and C from composite signal4. RGB - Usually use PC, 15pin D-sub 5. Analog Component (Y,Pb,Pr) - Usually Component6. Digital Component(Y,Cb,Cr)7. DVI(Digital Visual Interface) - Standard from DDWG(Digital Display Working Group) - TMDS(Transition Minimized Differential Signaling Signal) 8. HDMI(High Definition Multimedia Interface) - DVI+Digital Sound

A) Power Trouble Shooting
Power part is composed of power board and main board(small power)
Check connectors between power board and main board
Check main board power output on the board
When you check main board power(small power IC), There are two types of power IC. One is PWM type, another is regulator type. PWM type should check after inductor. Regulator type should check on the output pin.
Check each Voltage output
1 PWM Type 2 Regulator Type
Check After Inductor Check On Pin
V. Trouble Shooting
B) Analog Part
It is easy to check analog video signal than digital video signal
Use reference signal input ( EX. 16 Gray)
Check Signal Level and sync
Check Signal path until input of Video decoder
( Tuner → Switch → Video Decoder, AV Connecter → Switch → Video Decoder, Scart → Switch → Video Decoder )

C) Digital Part
It is difficult to check digital video signal because of too fast and small signal
Check digital video signal, Use H-sync, V-sync and Clock for basic
Each digital video ICs connected with data line, H-sync, V-sync and Clock line
Check H-sync period, V-sync period, Clock period If period is out of spec, Change the IC
