Type of A/S Complaints
1. SD Card Detection
1) Please check whether the SD card is inserted before booting GP2X or not. Because current firmware version cannot detect SD card when SD card is inserted after booting, please make sure to insert SD card before booting GP2X. Through firmware upgrade, soon we will make the detection of SD card possible even if it is inserted after booting.
2) Please check the capacity of the SD card. Because current firmware version cannot detect 2GB SD card, we will patch it through the firmware upgrade soon.
3) Detection problem depending on SD card manufacturer:
Recommendable SD card brands proven through our test so far are as follows:
1. Transcend Mind-SD 128M, SD 128
2. LG SD 1G
3. Teravit 80X SD 1G
4. UMAX 60X SD 1G
5. Imation SD 512M
6. Sandisk 1G, 512M, 256M (SDSDB-1024-A10 수입제품)
7. A-DATA My Flash SD 1G
8. I-O DATA SD 512M
9. MAX Ultra Pro II SD 1G
4) Speed and stability of SD: Current SD card driver may have problem in the speed of Reading/Writing. So it may have problem of intermittent stop while playing movie. Those problems shall be solved through continual upgrade of firmware.
5) NAND Memory Detection:
Though GP2X has 30MB NAND memory space available for user, but the space is not being supported currently. This problem shall be solved through firmware upgrade.
2. USB Detection Problem
1) USB detection process shall be as follows:
가) Check PC OS.
- GP2X does not support Windows 98
- GP2X supports Windows 2000 (Service Pack 4.0 and up are recommended to be installed )
- GP2X supports Windows XP
나) Please check whether the SD card inserted before booting GP2X or not.
다) Please insert USB cable. Rarely USB cable may have problem. If any problem, Check if USB cable is detected by other system or not.
라) Please select Setting USB from the Menu after booting.
2) When PC does not detect USB
가) If ! mark appears, please click GP2X homepage->Library->recommended article, and get USB monitor program downloaded and installed. After that, please repeat above-mentioned USB detection process.
나) If USB detection problem persists even after installing USB monitor program, it needs A/S.
3. Caution during Firmware upgrade process:
1) Please make sure to format SD card in FAT32 method when upgrading firmware.
2) Though both FAT16 and FAT32 methods are applicable when not upgrading firmware, FAT32 method is rather desirable.
4. LCD Screen
1) White vertical line appearing on left end side: Please get the firmware upgraded after downloading file by clicking GP2X homepage->Library->Newest Firmware #2.
2) Different brightness between left and right half of the LCD screen:
Please upgrade with the above-mentioned firmware.
3) Inadequate brightness, diagonal waving, blinking: They are phenomena occurring after patching new firmware. We will upgrade the firmware soon after solving all the bugs related with the new LCD.
4) Taking off LCD protection film and protection panel vinyl:
Currently GP2X has vinyl put on its LCD and protection panel. Make sure to take off each vinyl before putting on protection panel on LCD.
5. Earphone jack:
1) Incomplete contact of earphone jack is primarily not hardware problem but due to incomplete insertion. You’ll only have to push earphone into the jack completely until you hear clicking sound. Please make sure the metal plug of the earphone not show at all if seen from rear side.
2) If both speaker and earphone sounds at the same time, the plug of earphone is not inserted completely. Carefully insert it till the end.
3) When both left and right earphone does not sound right even after being completely inserted, it needs A/S.
6. Assembly:
1) Very rare detection problem of the left key of Joystick
Very simple solution. No need to disassemble.
1. Hold stick just like you are going to fasten bolt.
2. Turn reverse-clockwise about three rounds softly pushing from time to time.
(Caution: Do not force abruptly. The key is turning around slowly!!)
3. Go to test mode and check again.
4. After checking, turn it around reverse-clockwise if necessary.
5. How to check the optimum state of the joystick.
- With the stick being pushed vertically, turn the stick one round. If it works all the way around, it is in optimum state !
* Expert in mechanical engineering recommended this method. He also experienced such a trouble when he over-fastened the bolt. ^.^;
The cause is over-fastening of the bolt.
2) Very rare USB cable problem
3) Very rare power switch problem
4) When red LED does not turn on, it needs A/S.
Above-mentioned 1)~4) are related with assembly. Send the unit back to us for A/S.
5) Battery case
7. Battery life
1) Movie test condition
가) Movie format: Movie(DviX 4, 320*240, 30Frames, 800Kbps), Sound(MP3, 2CH, 128Kbps, 44KHz)
나) Battery: Sanyo Ni-MH 2500mA, 1.2V
다) Current actual battery life: 3 hr 10 min.
라) Cause and Remedy: Electricity is draining to TV-out module. This drainage shall be solved by firmware upgrade and be improved to 4 hours.
2) MP3 test condition
가) Battery: Sanyo Ni-MH 2500mA, 1.2V
나) Current actual battery life: 5 hrs
* Current actual battery life shall be increased by firmware upgrade soon.
8. Others subject to firmware upgrade
1) Loading screen: To be upgraded for loading screen to appear automatically on turning on power switch.
2) Loading speed: currently 28sec 20sec under
3) Red LED bug: firmware upgrade
9. Application bug
