You cannot get a new board. The IC's need to be replaced. Possibly IC's U24 , U25 and U26.

You cannot get a replacement board. The IC has to be replaced , possibly 3. These are U24 , U25 , U26. You would need specialist tools and ability to do it yourself.

Why does innotab charging light blink when charging and will not charge?

the charge imdicator is suppose to blink when you plug the toy to the wall adaptor. if it doesnt blink then there's something wrong with either the adaptor, the adaptor port on the toy or the rechargeable power packs. now i said that the light is suppose to blink. but the frequency of the blinks shouldnt be fast. if that's the case clean the compartments and re-insert the batteries. if you are still having problems try the ff T/S:

1)remove the power packs, plug the toy to adaptor and turn it on. if it turns on that means your adaptor is working.
2)remove the adaptor and try using just the power packs.
3)try using 4aa batteries.

if the toy turns on with only one of the power sources stated above you better call vtech hotline.

Why My Inspiron mini will not start?


It is unfortunate that the computer is not turning on. Request you to try following the below steps which might help:

    (1)Turn off the computer.
    (2)Remove all the external peripherals like AC Adaptor, flash drives, battery, etc.
    (3)Press and hold the power button for 30sec which releases the static on the computer (if any)
    (4)Put back the battery and plug in the AC Adaptor.
    (5)Let the computer charge for some time.
    (6)Try turning on the computer.
    If the computer doesn't turn on then check hoe the Power LEDs on the system, battery and AC Adaptor react. Then I can check and help you further.

    Thanks and Regards.

Casio keyboard will not power on

2 possible solutions to look at.

1) Ensure that the power adaptor is the correct polarity. Ideally you should use a Casio power supply rather than a generic one. For Casio the centre pin must be - Negative. Many power supplies have + as the centre pin, this is therefore like connecting the batteries up backward - IT MAY DAMAGE YOU KEYBOARD

2) The socket on the keyboard where the adaptor plugs in is prone to breaking and coming loose from the circuit board Looks something like picture below ( maybe grey ) This can often be diagnosed by holding the power adaptor plug where you clip it into the keyboard and moving it at the same time as turning on. If you get any lights the socket is faulty and will heed to be replaced. If you post the model number I can advise on socket needed.

3) More serious internal damage possibly as a use of wrong power supply ( see note 1 )

Good luck in tracking the fault.

Compaq M2000 turns on using charged laptop battery but doesn't charge or turn on when using power adaptor, with or without the laptop battery

1) The AC adapter should ALWAYS be plugged into the laptop FIRST, then plugged into AC power. If not, this could create a voltage spike.

2) Let's look at the DC Power Jack, for the Compaq Presario M2000 series of Notebook PC's,

The DC Power Jack is mounted to a removable circuit board.
Enlarging the view of the jack, shows us there is an Inductor.

The small 'can' standing up on the power board. This chipset could have gone south. (Bad)

How to know? Replace it, or dig out your dual trace oscilloscope. See if the Inductor works.

Could also just be cracked solder joints, of the DC Power Jack, TO that small circuit board. Solution would be to resolder it/them.

[ I WOULD however, search for a BETTER price, than listed in the link above, IF available ]

DC Power Jack is in good shape, soldered tight to the motherboard, and ruled out as the problem?
(Since you know the AC adapter is good)

Then the problem would be the Inductor on that power board, or power correcting chipset.

What one is it? Dunno.
DO KNOW is has J leads on the bottom.
CAN give examples, and perhaps you can identify using them.



Service Manual, (Free), for Compaq Presario M2000 series of Notebook PC's,
(Remember, follow Anti-Static Precautions. USE an ESD wrist strap, and connect it's alligator clip to a good ground source),

Drop down to the line that begins with - Compaq Presario 1100.
(1100 in blue)
Scroll over, click on M2000. (In blue)

(Ignore if you are aware of the following;
PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name { M2000 }, it may take up to 30 seconds, before the first page comes up )

My tv just died no power on my protron pltv 3250 power is at the plug in box but tv shows nothing.

Hello Bkobert, hi, before going through the set, kindly check first the following.

1. Check your mains AC line.
2. Check your TV plug cable, they may be loose.
3. Also check if the plug has a user fuse.

If ok, then there is a problem with your TV's switching power supply, a fuse on the board may be open, or loose wiring inside.

The symptoms may go to the extreme, like a faulty switching regulator section, which include the power transistor, IC regulatorm dried up capacitors, and low value resistor.

You may also choose to replace the entire board. thats all. keep me posted

Vizio 42 hdtv mo picture,no sound


Thanks for using FixYa. Please check the following—

1. Is Power board output +5V?
2. Is J1 (#19 in the right diagram)connector good?
3. Is DC-DC OK, check the voltage at J1 using a multimeter.
4. Is U4 (3.3V) working ok, U4 is an IC, you’ll need an IC tester or an oscilloscope to check this IC.

After checking this if it still doesn’t work then check P3 D-sub Input (on the D-board). See this schematic for details--


Please do accept the solution if the issue is resolved or else revert for further assistance.

Wont turn on


you have one of 3 things wrong here.

1:) the battery is dead, and needs to be replaced ( suggest e-bay china seller for cheapest )
2:) the AC adaptor or dc socket on the motherboard is Faulty.
3:) motherboard fault, regarding charging circuit board.

Go for the most cost effective option First. New Battery. Then AC Adaptor. Finally would be motherboard replacement.

Unit dead.
Local repair shop said it's un-econimical to repair.
Admitted they had no service manual.
Said they could 'have a look' but likely repair cost would be over $300. Charged me $50 for quote. Useless Gits.

My opinion & findings.
Power supply sensative to spikes.
I Suggest a power filter in-line with unit.

Disconnected all sub-boards from main.
Hiccuping PSU (5v wobbles between 2&3V).
Replace switchmode IC & feedback IC. No change.
Eventualy identified short-cct diode as listed below.

0402-001194 Diode is a Gen-purpose 200V 2A diode. I used a 1n4007 (1A), so I expect to have to replace it in future. It's "D1S35" located very close to right rear corner of main board, part of 15V and 12V rails. Next time I'll use a 'faster', higher rated diode.
I also had no clock progression. Time could be set but would not advance. Been like that for ages - I thought it was a user clock-setting error. Identified Dead 32.768 khz crystal (XT601).

Hired manual $10 +postage
Non-faulty parts + postage $40
1 diode $1

Satisfaction, plenty.
