You can always go on e-bay to look for a replacement motherboard.
Sometimes you can get a non-working board that is being sold for parts.

Im looking for a dixon tms8 circuit diagram


Are you trying to repair it? If so you dont need one. Test the mosfet to see if they are shorted. Replace all needed, look on board for bad components, such as bad or leaky caps, burned diodes, check other parts around each one. Check in transistors for short or opens, replace as needed. Look for input caps swollen etc, etc. they are all built almost the same way, some with better parts cheaper ones with lesser an weaker parts.

Sony TV Error Code - Nine Blinks Solution.


Nine blinks of the standby light on any Sony TV indicates a problem on the "G" board. It is located on the left side of the unit looking from the rear. I seems that Sony sent out some sets with faulty diodes in them which fail at some point. They have corrected this and changed the part numbers on newer units. I listed that information below. You must have one of the older units. Do not resolder the diodes as the problem will return in short order.

Here is the error code explanation along with the repair procedure:

" Nine blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will only fix the problem temporarily. This could also be a Panel Module Error or Thermal Error but most likely the diodes. If it is an intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 vdc(negative)."

The G board part number is A-1054-157-A. This board is no longer available from Sony. Rebuilt boards are available at http://www.moduslink/pts.com . The phone number is 1-800-844-7871 or you can go to their easy to use website and order a board. I have used them for years and have never had a bad board in fact their boards are probably better than factory. Certainly their warranty is (6 months).

Here are the diode part numbers and generic part numbers, and they can be purchased at www.partstore.com or www.encompass.com .

REF. NO. -SONY PART NO. - DESCP - GENERIC PART #
D6116 ----- 8-719-081-97----------DIODE --------MMDL914T1
------------------------------------------------------------No longer available

New part numbers:

D6116------ 8-719-074-43 -------- DIODE -------- BAS316-115
D6301------ 6-500-567-21--------- DIODE ------- 10ERB20-TB5

Remember, do not get cheap and only replace one diode at a time as you will still have the potential for failure. Also as I mentioned previously, resoldering will give you a temporary fix with the problem reappearing in a week or two.

This should solve your problem but I do know of one instance where a CRT (blue) was shorted out and caused this same problem, and the problem was not the G board.

To eliminate that issue remove the CRT boards one at a time (Blue, Green, Red) and turn the unit on with that color board removed. Of course remove power when unhooking the CRT board.

Continue doing this until all the boards are removed. If the set runs after removing any board, that CRT is bad and needs replaced. I have a tip at http://www.fixya.com/support/r4573850-change_crt_in_projection_tv which explains how to successfully change the CRT and where to get the parts. If the set never starts up the G board is most likely your problem and will need the diodes replaced.

This is all the info you will need to successfully repair your TV set. Good Luck and be very careful as there are lethal voltages inside the set.

Thanks for using FixYa.

Power supply fault [d212 short]


sounds like a bridge rectifier diode has shorted replace the bridge or make your own use 4 1000 piv diodes. can be purchased at radio shack. be sure to connect the diodes annode to cathode when making the bridge. also when a component shorts it generally opens the next component in series.in youre case i would definatley check the filter caps.sometimes if overloaded they will actually be swelled otherwise you will have to take them out of the circuit and read them with a cap checker on a quality multimeter. if bad be sure to mind polarity when replacing! electrolytic caps have a positive and neg. leg the board will be marked

We hooked up the cb radio and the meter light lit up.... my buddy tiltted the radio back and it started to smoke, i took the cap off and the smoke was comming from under the echo board, we fixed one...


If there was a direct short to ground.....which it sounds like there was....it would've blown the protecton diode. The protectio diode is located near the power plug on the inside of the radio (component side). It will be black with a white stripe at one end, It looks like a little can/cylinder with wires coming out of each end. Kinda like a resistor.....but smooth.
The problem lies HERE.....
If it did burn the diode, it will not look like that, It will be a crispy little black thing that falls apart when you touch it.
Just look around near the power plug for a burnt component. If you see one...well...thats probably it.
FYI: the diode will be directly between the pos and neg leads in the circuit near the plug.
Also...CHECK THE FUSE!!!!

One more thing. If the radio started smoking when you tilted it....that means that there is something metal rolling around in there loose. Thats the only reason it should've shorted like that.
Good luck!!

Bought Memorex MVD2059D 20" tv w/built in DVD player 7-21-09. Did not take out box until I drove my son 4 hours away to college on 8/22/09. TV worked 8/22/09 and on 8/23/09 the power went out and tv never...


IF the Standby Red Light does not come on when you plug in the TV:


1) Check fuse on back panel next to power cord. Pull out cord and pop fuse holder out. On an ohmmeter, it should read 0(short)-that is a good fuse.

2) Check the fuse on power supply board next to power connector. It is soldered onto board.

3) Be careful with this step: With all boards screwed in place, plug in TV and then unplug it. Next take a Voltmeter set on 200 Volts and test large electrolytic cap in middle of board-should have @100-200 volts on it. Do not short the capacitor-big fireball flash explosion if you do!

If 1-3 test OK, then:

D10 is shorted. HER304 in middle of Power supply board near large electrolytic cap. Replace with same diode or Radio Shack 276-1144 3A 400PIV Diode. PLEASE BE CAREFUL WITH HIGH VOLTAGE PRESENT ON POWER SUPPLY BOARD. UNPLUG POWER CORD!!! OBSERVE PROPER POLARITY WHEN REPLACING DIODE-LOOK WHERE THE BAND IS.

VCR POWER ON PROBLEM


On vcr power supplies usually first component to go is a capacitor, check if its blown, or test it if you have a meter capable, next check diodes and resistors, also check the resistors and diodes on all the boards( they may have blown if a cap has blown) If there was smoke or a smell its usually a resistor to look for. When you replace them replace them with a higher votage cap.. Example 15v 1000uF cap with a 25v -35v 1000uF cap( this is just to avoid the problem from happening again.

What you saw smoke was the protection diode. I do not have one of these radios and have not worked on one yet, but most radios are the same where the protection diode is located on the pc board, one the components side, close to where the wire from the main power positive pin is soldered into the pc board.

I will have to do a little research to see if I can come up with the number of the diode. I have a couple of diagrams and a schematic from cbtricks.com. If I can not located it from their informaiton, I can contact my supplier Monday to see if he can tell me the number. If you happen to located the burnt diode before I come up with the information, please respond so I will know.

GE spacemaker xl1800 and Pop tarts bad mix


it sound to me as if the high voltage diode is shorted. It could be inside the capacitor or out board the cap. The capactor could also be short but this is a rarity. Diodes are a cheep item . repace it and if it don't work its probably the magnatro. good luck.

remove pwr board--inspect and you will find a heavy current diode which has eatin its solder pad area--if diode checks ok,repair it's connection.Install board and hook back up.Check for shorts in circuit.Cross fingers and plug her up------good luck

Hi there! I think it's not possible to replace the diode as these components are machine soldered to the board. If a machine soldering facility is available to you, you could possibly replace the diode (choose the same diode model adjacent to the one which is damaged. All the best to u.
