    Then why did the set start changing channels and volume movement with board unplugged ? IR remote sensors have been known to go bad and spit out bad data. Ok I have to get back to the set and try new switches Thanks but while on the jobsite I thoroughly checked the switches but not to the point of removing them

Techwolf, you nailed it, control board is bad, I have personally checked the tact switches and they checked good with Ohm meter but the meter lies, problem is module/board is kinda pricey and individual tact switches are not listed individually on parts list, you also have to be carefull that you get the correct one, there are 3 versions of your posted model #, AV48WP30, AV48WP30A, AV48WP30ME, be sure to check which one you have, should be able to order module here; I have tried cleaning tact switches with "blue shower" but fix doesn`t last, have to change module out, good luck, BMW Rider

If you are having problems playing a blu-ray disc is your blu-ray player, try the following.
1) Check the firmware-make sure you have the latest version. If your BD player uses the Xross media bar, following these steps:
Press the Home button.
Select setup
Select System Settings
Press the Enter button on the remote.
Scroll down and select System Information and press enter.
The Firmware version will appear on the screen. Write this number down and go to to see if you have the latest version. Just follow the instruction to perform the update. Check out this will walk you thru the steps I just described.
2) If your BD player doesn't have internet connection, you can check the firmware version by:
Press the System Menu button.
Highlight Setup and press the ENTER button.
Highlight Video Setup press the ENTER button
Highlight TV Type and press the ENTER button
On the remote, press the Blue button
The current firmware version of the player will display. Write this number down and go to to see if you have the latest version. Just follow the instruction to perform the update. Check out this will walk you thru the steps I just described.
3) Some BD players requre that a USB memory device is inserted in the EXT slot of the player prior to playing the movie. It's recommended to use at least 1GB. If you already are using one and run into a disc not playing, try removing the USB device and plugging it back in.
Here's a few more things you can try.
1. Reset the BD Player:
  • Remove the disc from the BD player.
  • Turn off the BD player.
  • Unplug the power cord of the BD player from the electrical outlet.
  • Let the player remain without power for one minute.
  • Plug the power cord back into the electrical outlet.
  • Turn on the BD player.
  • Insert the disc into the BD player
2. Make sure that the Parental Control settings are not set to "On".
3. If the BD player supports the BD-Live feature, set the BD Internet Connection setting to "Do Not Allow" and delete any conflicting BD-Live date from the BD/DVD Viewing Settings menu.

I have a 2000 chevy s10 2wd. Where is the relay switch to my drivers side window. The window switch is and the motor is good. But cant find the relay switch to check it and see if it's bad.

Sorry but there is no relay switch ! Go to free wiring diagrams .Check it out ! Your regulator is probably bad ! Is there B+ voltage at the switch , at the motor ?
Left Front Window Switch Operation
Place the ignition switch in the RUN position in order to supply battery voltage to the left front door lock and side window switch through the POWER WINDOW circuit breaker and the CKT 1001 (DK GRN). Press the left front window UP switch in order to supply battery voltage to the left front side window regulator motor through CKT 164 (DK BLU). The window motor is grounded through CKT 165 (BRN) and the window switch DOWN contact.
The regulator motor runs to drive the window to the UP position. Press the DOWN window switch in order to provide battery voltage to the window regulator motor in the opposite direction through CKT 165 (BRN). The window regulator motor is grounded through the CKT 164 (DK BLU) and the window switch UP contact. The motor runs in order to drive the window down.

Refrigerator has a clicking sound and does not run

Replace the motherboard (part # WR55X10942) but be careful to check that the evaporator fan (inside the freezer) turns on when you power up the refrig again. A bad evaporator fan motor can take out the motherboard. If compressor starts with new board but not evap fan, unplug immeadiatelly and replace the evap fan motor to save new board.

Samsung tv model no LE40R74BDXIXEU TV IS USUALLY

First the main bd controls the "Turn on" sequences". When you press the Power on button the Main bd sends a "Turn on" signal to the Power supply. The clicking you hear is the Power on relay ativating. If the tv does not turn on and the relay keeps clicking then you might have a bad Main bd or there is s shorted board somewhere else in the set. The Power supply can also be bad. Have a trained Samsung tech troubleshoot the set.

Multiple causes here. The Main bd controls the Power supply. The Main bd receives the "Power on " signal from the IR sensor and the Power Button the tv. Seems that the Main bd is not sending the Power on signal to the Power supply. So the first place to start is with the Main bd. Second being the Power supply. have a trained Samsung tech troubleshoot the set.
