Description

The JVC AV-27D303 is a 27-inch CRT television released in 2002 as part of JVC's D-Series consumer line. This late-era D-Series model features the GE3 chassis with Toshiba TM8812C- jungle IC. The silver bezel design marks the transition from the earlier black cabinet D-Series.

Technical Details

Chassis

The AV-27D303 uses the GE3 chassis, featuring the Toshiba TM8812C- jungle IC. This late-era chassis represents a cost-reduced design and cannot be RGB modded - the component video inputs provide near-RGB quality, making modification unnecessary for most users.

Unlike the earlier GE chassis, the GE3 lacks the E/W circuit, resulting in some barrel distortion that cannot be corrected. The 3-line digital comb filter provides quality composite and S-Video processing.

Tube Identification

The tube brand can be identified by the letter beside the serial number on the back of the set:

R = RCA/Thomson (A68ADT25X)
S = Samsung (A68QDN891X)
B = Goldstar/LG
M = Matsushita/Panasonic

Audio

The AV-27D303 uses a 1.2W × 2 stereo power amplifier with BBE Sound Enhancement and Hyper-Surround processing.

Red Push Fix

Late-era D-Series (Dx03) 2002 models may exhibit oversaturated reds. To correct this in the service menu:

Navigate to NTSC MAT → Set to 000

(Note: 2003-2004 Dx03/Dx04/Dx05 models with later revisions have no known red push fix)

Setup Tips

If component video appears in black and white, enable "V2 Component-In" in setup menu
Default sharpness is typically too high - adjust in user menu for optimal picture
To disable vertical edge enhancement, set LYC02 to zero in service menu (3L Y/C sub-menu)
Front Input 3 jacks are under the front panel door

+=== Audio ===
-The AV-27D303 features a black plastic bezel with bottom-mounted speakers. The control panel is located on the front right side of the television with volume, channel, and menu controls.
+The AV-27D303 uses a 1.2W × 2 stereo power amplifier with BBE Sound Enhancement and Hyper-Surround processing.

+Late-era D-Series (Dx03) 2002 models may exhibit oversaturated reds. To correct this in the service menu:

-== RGB Mod Information ==
+(Note: 2003-2004 Dx03/Dx04/Dx05 models with later revisions have no known red push fix)
-This model '''cannot be easily RGB modded''' according to community reports. The chassis design is not readily compatible with RGB modification, and more importantly, the gains over the existing component input would be marginal due to this model year's very good component decoding. Since the AV-27D303 already includes high-quality component video inputs (YPbPr), it can display near-RGB quality video, making an RGB mod unnecessary for most users.
 == Setup Tips ==
-* If component video appears in black and white, access the setup menu and enable "V2 Component-In" for INPUT 2
+* If component video appears in black and white, enable "V2 Component-In" in setup menu
-* The default sharpness level is typically set too high, causing ringing artifacts. Adjust this in the user menu for optimal picture quality
+* Default sharpness is typically too high - adjust in user menu for optimal picture
-* To disable vertical edge enhancement (which artificially boosts contrast on vertical transitions for composite and RF sources), set LYC02 to zero in the 3L Y / C sub-menu of the service menu
+* To disable vertical edge enhancement, set LYC02 to zero in service menu (3L Y/C sub-menu)
-* The television includes I2C bus control for advanced service adjustments
+* Front Input 3 jacks are under the front panel door
-* The front Input 3 jacks are located under the front panel door - pull to open
