REPLACEMENT OF MEMORY IC

This TV circuit uses memory IC. In the memory IC are memorized data for correctly operating the video and deflection circuits.

When replacing memory IC, be sure to use IC written with the initial value of data.

PROCEDURE FOR REPLACING MEMORY IC

(1) Power off

Switch the power off and unplug the power cord from AC outlet.

(2) Replace IC

Be sure to use memory IC written with the initial data values.

(3) Power On

Plug the power cord into the AC outlet and switch the power On.

(4) Check and set system default value:

1) Press “MENU” key followed by digits '6''4''8' and '3'. Then Press “TEST” key on the Remote control unit for factory used.

2) The red “M”or”factory” will be displayed on the screen, repeat this and it will changed as follow: 

normal-M(factory)-BUS open-normal..

3) Press digital key, (Mkey) and corresponding on-screen display will be appeared.

4) Check the setting value of the SYSTEM default value of Table below. If the value is different, select items by [CH+]/[CH-] keys and set value by VOL+]/[VOL-] keys.

5) Press “STANDBY” key again and return to the normal screen.

Sharp LC-32A28L– Sharp LC-42A48L – Service mode – adjustments – SMPS circuit diagram

How to enter service mode Sharp LC32A28L and Sharp LC42A48L LCD TVs – Alignment procedure – Power supply 715g 4009 and 715g 3905 - Schematic 

SERVICE MODE
To enter factory mode [Service mode] menu: press MENU + Numeric keys “1999” to enter factory mode.
To Exit, Power OFF.

Alignment method
Initial Set-up

22. Select ”19. Color temp” item and change to “User”.

23. Copy “Normal” adjust value to 20. Scaler R GAIN, 22. Scaler B GAIN, 23. Scaler R Offset, 25.Scaler B Offset.

24. Select ”26. Clr temp Copy” item and press RC “ X”. The User adjust value will copy to all of input source automatically.

Tolerance ∆x, ∆y = +/- 0.005

Factory alignment tolerance at 80% white ∆x, ∆y = +/- 0.005 at 20% white ∆x, ∆y = +/- 0.009

Check the 16 grayscale pattern should be distinguished and color bar is correct

Reset AV setting in OSD menu, picture mode shall be recalled to be “Standard” mode.

1. Use Minolta CA-210 for color coordinates and luminance check.

2. Before adjusting,all colour analyzers (CA-210) should be coordinates with a same reference TV set.

3. Luminance > 400 cd/m2 in the center of the screen when Brightness control at 100; Contrast control at 100.
