It is simple to remove. You have to remove the back of the TV (you will also have to take the cover off the back of one of the speakers to access the screws for the power supply cover. Then there will be thin metal covers over the main controller board and the power supply (the power supply is covered by the smaller of the two). Once you have the covers off the power supply has 4 to 5 screws holding it in depending on the model and 5 plugs that connect it to the power switch on the bottom and the main controller board. All I will need is the actual Power supply if that is the only issue. You will need to pack it securly and ship it to me. Leave me your e-mail so I can send you the address. Payment can be by Cash with the board or by PayPal. You should be able to calculate the return shipping when you ship it to me. Be sure to include return shipping as well.

I have a behringer MX2804 which has 3 faulty channels, they allow a small signal to go through them but it appears to be the gain controls that do not work properly. Does anyone know what the problem could...


If the problem appears to be the faders, you can try putting a little CRC226 into the center of the slot of the faders. You can get this in the electrical dept of Home Depot. Use of Deoxit and other cleaners destroy the lube in the pots and then wear of the slider causes failure. Replacing the pots requires a lot of labor to access the pots, namely removing knobs and screws. Great care must be used in removing the pots from the circuit board as use of non-professional desoldering tools often damage the board. These have ROHS solder requiring higher temperatures for removal and use of manual desoldering plungers and solder wick usually lifts circuit traces destroying the board. If the CRC 226 doesn't fix the pots, best take it to a repair shop.

Sony KP51WS520- stand by light flashes 9 times and won't turn on. Have unpluged for 4 hours, still won't turn on.


Unplug the tv, take the back off,locate the G board, next look for D 6301,and D 6116,these are diodes,desolder them and replace them,if that didnot fix it,then change the switching regulator also,its also on G board..use a desoldering iron to remove parts, then wick wire to get the access solder off the pin holes to resolder parts.hope this helps.....

Hi does anyone know how to repair or replace a broken zoom on my fuji finefix S1000 camera?


Yes, I do.
You will have to strip the camera down and desolder the main board from the control/flash board just to remove the lens. Once this is done then the lens can be dismantled and the control ribbons desoldered etc, etc....
It's a long job.
And watch out for the springs!

Removing the hyper board


I ordered a Next HYPER Board, PD0264A (as seen in the service manual). I ordered it from Vance Baldwin Electronics (vancebladwin.com) The only part available is a substitute, PN 23148017 MODULE, SCAN CONVERTER. The cost was 219.50. It was backordered so it did not arrive for almost 3 months. Install is a little tricky. It is accessed from the back. You need to remove the input board, the video processor, and some brackets to get to the Hyper board. The hard part is putting the TV on either its front or back (much eaiser if its laying on the screen, although more dangerous) and then desoldering for tabs that go through the signal board. There is a lot of solder on these and two of them have been twisted for some pain in the **** reason. They are difficult to twist back without damaging anything. When it is desoldered and twisted back, the board should come out. Be careful not to crack the signal board when pulling this out as I did. See above for what it does. I found a slight chip in my signal board and it took some difficult board repair to get the runs connected again (please be careful, as the repair is difficult and not nearly as relaible as an unbroken board.

Anyways, install your new board, put everything back, and power it on. I'm sure you'll have to do a convergance and some other adjustments, but if your doing this fix, a convergence should be cake. My problem has been fixed and I'm thrilled to not have to trash my TV.

Pioneer DV-C36 disc tray will not stay open


Solution for Pioneer DV-C36 Multi Disk DVD player - tray door will not stay open.

My player would open the disk tray when the open button was press but when the tray was fully open it would retract
back into the unit leaving no time to change or load disks.
I found a poor connection at the ribbon cable connector was causing this problem. A seven conductor ribbon cable
connects the main unit with the travelling tray. A position switch (S21) senses when the tray is fully extended and retracted.
On my player pin 1 of the ribbon cable connector on the travelling tray was not making an electrical connection which
causes the control system to retract the tray. The fault lies in the connector - the tang was not pressing against the ribbon cable conductor.
I was able to desolder the connector and pull the contact out just far enough to reform the tang with fine needle nose pliers.
This is very tedious and required an eye loupe for magnification.
Tools required:
#1 and #2 phillips screwdrivers
Soldering and desoldering irons (or other desoldering tools)
Fine needle nose pliers.

Remove the tray ribbon cable
1. Remove the cabinet cover - 6 screws. Open the tray. To keep the tray from retracting pull the power cord when the tray is extended.
2. Remove the front bezel from the tray. Gently pry up the bezel by relesing the catches with a small screwdriver. Allow the tray to retract.
3. Remove the front panel - undo large ribbon and wire connections on right, remove screws left and right, release
two catch tangs on bottom edge using a small screwdriver on the inside of the unit.
4. Remove the white plastic cover over the laser mechanism ( 2 screws) Remove the disk carrier by removing the center screw.
5. Extend the tray again. When the tray is out the small ribbon cable is visible below the tray. Undo the ribon cable where it attaches to the main unit unit.
6. To slide the tray off the main unit use a small screwdriver to depress the stop catches (2) in the tray. They are molded into the tray.
Pull the tray out further then lift up.
7. Flip over the tray and find the small circuit board the ribbon cable goes to. Desolder the motor wires (red and black) and remove the 2 screws
holding the circuit board and position switch.

Use a multimeter to confirm there is an open or poor connection in the ribbon cable connector.

Remove the ribon cable and inspect the connector with an eye loupe or other magnification device. On my player contact #1 was not positioned properly
to press against the ribbon cable conductor. You can either replace the connector or repair it.
Warning: repairing the connector may damage it.
To repair the contact desolder the connector from the circuit board. Bend the circuit board prong straight and push it into the body of the
connector which will extend the contact out and the contact can be reformed. Be very gentle. Bending the contact may cause it to break.

Reassembly is the reverse. Don't forget to solder the motor wires with the proper polarity. Red and Black are labeled on the circuit board.
