Question about JVC FS-7000 CD Shelf System

1 Answer

Failure Of Main Chip

Refuses to recognise CDs and told by repairer that the main chip is faulty. Replacement could be expensive because apparently there are a number of versions of this chip. My contact 'Snakehead' suggested 'shocking' this chip. Is this something i could do for myself?

Many thanks

My compaq nc6000 laptop when i turn it on the fan fan turns for some secong after that it shuts dawn also it had bo ant display whta can i do?


Hi tadzfuture

HP COMPAQ NC6000 NOTEBOOK POWER UP FAILURE

This sounds like Graphics Chip failure or Motherboard Power Management Fault. However some other potential, less serious causes of the symptoms you describe must be eliminated first.

First, remove the battery, then connect the laptop, in a battery-less condition, directly to the mains electricity and power it up to test the boot process again. If no image appears but the computer seems to boot normally and the Hard Drive activity light flashes, there might be a faulty or failing:

LCD Panel Power Inverter (LCD Screens only)
Cold Cathode Backlight (LCD Screens only)
LCD or LED Panel

All these items are testable and replaceable. To be certain, send the image from the laptop to an external desktop monitor of LCD TV by pressing and holding the Fn key and then pressing the Function Key with the image of 2 monitors on it (often the F4, F5, F6 or F7 key).

If no illuminated LEDs are visible, particularly a Hard Drive Activity LED, then the DC Jack's connection to the Motherboard might have worked loose or failed or the Motherboard's Power Management System might have failed.

If when you power on the laptop you see a Power LED but no Hard Drive activity LED and nothing on the screen, the Graphics Chip might be faulty. Faulty Graphics Chips can are indicated by a regular flashing or permanent "on" state of the Power LED at the front of the notebook when you try to power it up and can be repaired by Ball Graphics Array Reflow or BGA Reballing. These repairs have an average success rate but can be expensive and must be done by an experienced specialist with specialist equipment such as an Infra Red Workstation, an Oscilloscope and a Micro soldering Station. The fault can come back. BGA Reballing generally achieves better, longer-lasting results than BGA Reflow but can be more expensive. A reputable, specialist motherboard component level repair centre should be able to offer you a No-Fix-No-Fee Graphics Chip, Motherboard Power Management System or Loose DC Jack repair service and a 3-6 Month Re-repair or Full Refund Post Repair Same Fault Warranty. Sometimes the surface of the graphics chip is too damaged to repair.

If the Graphics Chip or Motherboard is irreparable or the cost of Graphics Chip or Motherboard Component repair seems expensive to you compared to the current market value of the laptop, then consider buying a new laptop, having any important data transferred to the new laptop, formatting the old laptop's hard drive, offering the working components (LCD Panel, Power Inverter, Hard Drive, RAM Memory Modules, Battery, AC/DC Adapter, Wireless LAN Card, Keyboard, CPU, CPU Heatsink, CMOS Battery, Lid Frame, Chassis) of the old laptop for sale on eBay or some similar website to recoup some cash. Dismantled, functioning, 2nd User Laptop Components have far more cumulative value than an assembled, non-functioning laptop, which only has low scrap, value.

Also, always use a surge protector for computer equipment, never directly to the mains.

If the battery cells are dead, you may also require a replacement battery.


I suggest you take the laptop to a repair shop for testing of the components listed above and/or a quotation for graphics chip repair.


I hope this helps.

I have a hpg61 laptop when i turn it on i get a blank screen and a beeping sound


Hi drl9390854

HP G61 BEEPING AND BLANK BOOT SCREEN

Beeping during boot usually indicates a problem with the RAM Memory or a Cooling Fan Failure fault.

Check that the installed RAM is compatible and properly installed or, if faulty, try alternative RAM.

A failed Cooling Fan will prevent the computer from booting to protect the CPU. If the fan has failed, the laptop must be disassembled for a replacement fan to be installed.

If when you power on the laptop you see a Power LED but no Hard Drive activity LED AND nothing on the screen, the Graphics Chip might be faulty. Faulty Graphics Chips can are indicated by a regular flashing or permanent "on" state of the Power LED at the front of the notebook when you try to power it up and can be repaired by Ball Graphics Array Reflow or BGA Reballing. These repairs have an average success rate but can be expensive and must be done by an experienced specialist with specialist equipment such as an Infra Red Workstation, an Oscilloscope and a Micro soldering Station.

I get a blank screen and 4 beeps what's the problem?


Hi,
This could happen when the RAM contact is not proper, may be due to dust. Remove the memory modules from DIMM slot, clean it (no moisture please) and reinsert it. This could mostly solve your issue.
Please come back and rate my solution if it turns helpful for you or also if you need more clarifications. Thnx

My printer doesn't recognise the new refill; and i can't seem to overide it to print. I tried a cheaper refill and then bought a genuine epson and it still doesn't recognise the replacement cartridge. ...


If this printer takes the Epson 69 cartridge you need to make sure the chip is replaced or reset on the refills you buy. I own a Cartridge World ink refilling store and I can't fill these cartridges yet because there are not replacement chips (that don't violate Epson patents) or a resetter for the chip. The chip communicates with the printer how much ink it thinks is left in the cartridge so you don't run it dry and ruin your printer. Once the chip says the cartridge is empty it will refuse to print until the chip is reset. It seems to me like you bought two refill sets from sellers that are scamming the consumer by not mentioning the chip problem. This is the main reason why I don't recommend internet refills is because it is really easy to take advantage of people. I would not buy refills until a reputable store like Cartridge World or Office Depot sells refills.

WHEN I TURN MY LAPTOP ON I HEAR ONE LONG BEEP FOLLOWED BY TWO SHORT BEEPS AND THE SCREEN STAYS BLANK. WOULD GREATLY APPRECIATE ANY HELP


Dear Check your ram because it is 100% RAM's fault. If you are using two RAMs, you should try with one RAM and then try to power on if it will work its mean you have found the fault and problem have solved. If the problem will remain same and then you should replace the second RAM and pull out the first RAM and then try to boot up. I assure your problem will be solved.

Good Luck

Toshiba P20 video chip broken


If your friend is REALLY REALLY good with soldering circuit boards, it is possible to replace just the chip.

As far as getting the chip, have fun. You can try to contact nvidia and explain the situation and see if they can get you the chip special ordered, but I wouldn't count on it. There may be so rare dealer out there that may have a new chip but as far as I know, you aren't going to find one. I guess the other option is that you could contact different circuit repair and computer repair shops to see if they have any ties to someone who can get you this chip.

Here's my honest opinion though. For the time, effort, and money that you would have to put into finding, ordering, and replacing the chip (which I may add, this is an extremely unrecommended process, because one little mistake could fry the motherboard for good or the whole computer) you will probably be better off just getting a new board. This would be about the only way to obtain the chip anyway and it would be pointless to take it off and stick it on another.

Basically it comes down to this. It is probable that it can work. I would recommend getting a new board.
