HP - COMPUTER BIOS BEEP CODES
What to do when beep codes occur
Listen to the beeping sound and write down the number of beeps before each pause, if the beeps are long or short, or if the beeps high or low in tone. Once a pattern is determined, use the following beep code table to identify which component might be causing the problem: Use these codes to help troubleshoot problems related to system start-up or flashing BIOS memory (such as in BIOS upgrades). When troubleshooting further, refer to the section What to do when beep codes occur .
Four series of beeps indicate a fatal error; that is, a problem exists which prevents the computer from starting. For example, there might be two beeps, a short pause, one beep, a short pause, one beep, a short pause, and then three beeps; this is represented as:
Four series of beeps indicate a fatal error; that is, a problem exists which prevents the computer from starting. For example, there might be two beeps, a short pause, one beep, a short pause, one beep, a short pause, and then three beeps; this is represented as:
1 short beep and 1 long beep : Memory problem
2 short beeps and 1 long beep (repeats 5 times) : Unable to initialize video or video card required but not installed
3 short beeps and 1 long beep : CPU configuration error or CPU type is not compatible
The following beep codes can occur while restoring, flashing or updating the BIOS:
1short beep : Legacy floppy drive or CD/DVD drive not detected
2short beeps : Floppy diskette or compact disc not detected
3short beeps : Unable to start flashing (such as when missing a utility or BIOS image)
4short beeps : Flashing failed (checksum error, corrupted image, etc.)
5short beeps : BIOS recovery successful
Perform the following steps to resolve beeping issues. Before starting a task, turn off the computer, and then remove the power cord. After completing a task, replace any covers, reconnect the power cord, turn on the computer, and then listen for a beep code.
* Remove any media from the floppy drives, CD/DVD drives, USB ports, and memory card reader slots, and disconnect all non-essential devices (printers, scanners, external hard drives, and similar).
* Disconnect the mouse and keyboard, and then restart the computer. If the beeping sound stops, repair or replace those devices.
* Hot air can damage internal components! Remove any obstructions that block vents. Clean the cooling vents on the case to remove dust. If cooling fans stop spinning or make strange noises, service the computer.
* Remove the memory cover, and then re-seat all memory modules. If the computer stops beeping, a memory module might not have been fully seated or connected.
If the computer has multiple memory modules, turn on the computer with only one memory module installed. If the computer stops beeping, the memory module might be defective, or might be the wrong type of memory for the motherboard. Reinsert the memory into the socket to see if a connection was the problem; otherwise replace the module. Repeat this process for all memory modules installed in the computer If all of the above steps have been tried and the beeping sound still exists, refer to beep code table specific to the motherboard of the computer
Beep codes for American Megatrends, Inc (AMI) bios.
The following AMI beep codes can occur when there is a problem during the attempt of a normal system start-up. Use these codes to help troubleshoot problems related to system start-up. When troubleshooting further.

PLASMA TV - SAMSUNG PS42E7SX/XEC PDP-TELEVISION (P_Europe_42SD) TROUBLESHOOTING
* A fixed screen can cause permanent damage to the TV Braun tube: Braun, PDP and LCD TVs can all be damaged. When a still image is displayed in a sequence, this can leave stains or after-images due to the characteristics of the panel. However, the DLP TV has the advantage that no stains or after-images are left on the screen. The DLP TV has mirror pixels on the DMD panel that project the beam onto the screen, in which the mirror is a digital representation of 0s and 1s, leaving no trace of light. The mirror returns to a blank state so that no stains or after-images are left.
* Length of DVI Cable / PC RGB Cable: A too long DVI cable may cause a malfunction or degradation of the visual quality due to an attenuation of the signal. There is no recommendation for the cable length at present. In general, although a cable length of up to 5 meters should work, please check if video is
* properly displayed on the screen after connecting. If you think the length of the cable is longer than for normal use, check the visual quality of the video on the screen and shorten the length, if necessary. This also applies to the PC RGB (D-Sub) cable. When the length of the cable is longer than for normal use, video may not be displayed on the screen. In this case, shorten the cable length.
* When a digitally distributed TV user receives HD-rated broadcasts: The digital distributed TV (Ready Technique) can render HD sources as HD-rated.
* However, you need to install a set-top box for this purpose. The digital TV alone cannot render HD broadcasting as HD-rated. Install the formal set-top box for HD broadcasts.
* When a digital distributed TV user selects normal size (4:3) to receive SD-rated digital broadcasts: The digitally distributed TV (Ready Technique) renders any broadcasting service as SD-rated. However, when connected to a set-top box, the digital TV renders HD broadcasts as HD-rated and renders SD as SD-rated. The screen size is scaled to 4:3.
* When a digitally built-in TV user receives SD (air) broadcasting: The digitally integrated TV ("built-in" type) renders SD broadcasting as SD-rated. This can be understood easily. Even a high-resolution TV cannot improve a low resolution picture into high quality. In contrast, an SD-rated TV cannot represent HD broadcasting as HD because the resolution of the TV is lower than the original.
* When selecting a picture size of 4:3 in connection with a computer or a multimedia device: The representation capability of SD or HD-rated depend entirely on the TV set. The HD TV can render HD broadcasting as HD-rated only when it receives HD sources. In the meantime, the HD TV renders SD as SD-rated when it receives SD sources. The picture size has nothing to do with the resolution; TV models like SVP-XXL3HD or SVP-XXL6HD have a size adjustment feature to 16:9, 4:3, Panorama, Zoom1, Zoom2 and Auto Wide. This is about the aspect ratio of the top and bottom boundaries to the overall screen and users can select their preference.SD/HD broadcasts and the TV's display capability are related.
1. A digital broadcast should be transmitted in wide screen (an aspect ratio of 16:9) HD. If the broadcasting station converts a conventional program created in normal screen (aspect ratio of 4:3) into a digital signal and broadcasts the signal, the left and right of the picture will not be displayed. This symptom also appears in other manufacturer's TV's. The three appliance companies are trying to resolve the problem through the Ministry of Information and Communication.
> When watching an SD (normal) broadcast through a Digital (Wide) TV (480P normal broadcast)
> When watching an SD (normal) broadcast through a Digital Ready (Wide) TV (Using a set-top-box)
> When watching an analog (normal) broadcast through a wide TV. (When watching a broadcast after changing the aspect ratio of the TV from 16:9 (wide screen) to 4:3)
2. When watching a DVD title or video tape in wide screen (21:9) through a wide (16:9) TV, watching video from a computer or game console by selecting the aspect ratio to 4:3, or watching video from a DVD, VCR, computer or game console through a wide TV by selecting the aspect ratio to normal (4:3) or wide (21:9), the left and right, or top and bottom of the picture will not be displayed. This symptom appears in other manufacturer's TV's. The three appliance companies are trying to resolve the problem through the Ministry of Information and Communication.
Changing the Order of the Picture Size for 16:9 Display Devices.
1. When you want to change the picture size in PIP 'ON', you must turn the PIP off before changing the size. However, you can change the main picture size even in PIP ON for products with no restrictions.
2. When the picture size is not Normal (4:3 for 4:3 display devices, 16:9 for 16:9 display devices) and you turn PIP on, the picture size is changed to Normal. However, you can turn PIP on without changing the picture size for products with no restrictions.
3. In the OSD notation for the picture size, 16:9 is represented as "Wide" instead of "16:9" for devices other than with 16:9 displays. Ex: For LCD 15:9 devices, "Wide" is displayed on the OSD instead of "16:9".
4. The picture size can be changed even in the blue screen. However, the picture size should be controlled by the product specifications if the change is impossible due to hardware restrictions.

Symptom:
* The LEDs on the front panel do not work when connecting the power cord.
**The SMPS relay does not work when connecting the power cord.
*** The power of the unit seems to be out of order.
Major Checklist
The SMPS relay or the LEDs on the front panel do not work when connecting the power cord if the cables are improperly connected or the Main Board or SMPS is out of order. In this case, check the following:
* Check the internal cable connection status inside the unit.
** Check the fuses of each part.
*** Check the output voltage of SMPS.
**** Replace the Main Board.
When the unit is repeatedly turned on and off
In general, the SMPS relay repeatedly turns on and off by the protection function due to a defect on a board connected to the SMPS.
* Disconnect all cables from the SMPS, operate the SMPS alone and check if the SMPS works properly and if each voltage output is correct.
** If the symptom continues even when SMPS is operated alone, replace the SMPS.
If the symptom is not observed when operating the SMPS alone, find any defective ASSYs by connecting the cables one by one.
When separating and connecting the cables such as CN809 of the Main SMPS, CN1, CN2, CN3, CN4 and CN5 of DC-DC SMPS, CN of the X Main Board, and CN of the Y Main Board, a spark may be generated by the electric charge of the high capacity capacitor. Therefore, wait some time after separating the power cord from the unit.
