What you need is called a control box assembly. Let me see if I can find one for you....

    And it's not a $20 part. I service these things all the time under Polaroid's warranty. Here is where you can order them though.

    I know what you're saying. The CBA is pretty much the entire workings of the TV and it's a shame that they are so much. Honestly, I didn't think they'd be that much since a new TV costs about the same. This is the first time I'd ever priced one since all the ones I work on are covered by their warranty. However I am researching your issue a bit further...inside the control box assembly are two boards; one is the power board, and the other is the one that you would need to replace. Surely if I can find just this board, it should be cheaper than the full CBA.

    NP...can you verify model number for me? 3734b or 373b?

  • Kevin Shafer

    Okay, no problem. I've located the service manual for this TV, and it's the same for both models. Unfortunately, according to the parts list, it's only available in the assembly and that is what needs to be replaced. You may download the service manual which includes the schematics here.

    Inside the control box assembly (the piece that has all the inputs/outputs), is a power board on one side and the board next to it is the one that would need to be replaced (I'm thinking that there are only two boards in the CBA if my memory serves me correctly). Most of the time (i.e., all but once) Poloaroid just replaces the CBA which fixes most problems rather than swapping the boards out inside the CBA and now I know why...they aren't mentioned anywhere lol. But, since you are handy at replacing circuitry on the power board, perhaps the schematics in the SM will help you determine the faulty component on that board :c) Good luck!

My screeen has gone white on my tv how do i fix it on my element flx-2210 tv


Hello,

White screen only / no picture is a sure sign of a failure in the power supply board. Your TV is getting power to the back lights but the control board voltages are not getting through so it is not displaying the picture right. This is an easy repair to do, you will just need to replace the filter capacitors on the power supply board. This Element model is actually made by Funai and is the same as the Polaroid FLX-01911c TV. Here is a repair guide for that model that will show you what needs to be replaced to get your TV back up and running again.

I have a polaroid 32 inch lcd tv and im having this problem where i turn on the tv and the polaroid logo appears and after about 20 seconds the screen turns black. I can still hear sound but nothing will...


There are 2 capacitors located on a circuit board that have gone bad. They are located inside the TV. It is very easy to take apart and inexpensive to fix. If you know how to soldier you can do it or sent it away like I did to fix mine. On the back of the TV there are 3 screws holding on the cover. One is big in the middle and the other 2 are small on the ends. Remove them and slide the cover off. Remove the screws holding the metal cover and take it off.
The top circuit board has the blown capacitors. Located on the left top 2 small round tubes located at E17 & E18. Unplug the 3 or 4 connections carefully on the board and remove the 6 screw holding it in place. Take out the board and replace with new capacitors. I sent mine to JD Electronics in Poland Me. and he fixed it. I put it back in and it is fine now. I ordered the capacitors from DigiKey.com Part # 493-2069-ND. They were $1.09 a piece.
Hope this helps...........

Polaroid lcd-2000 tv won't turn on is this the power cord or tv


If you do not get ANY indicator light , then you need to look at the power supply for the 5vdc standby voltage first whic will be in the power supply module, this 5vdc is needed by the main board to turn on the rest of the circuit. If you do have even one light, the n the problem can be in the controller board not sending the signal to turn on the main power supply section. Look at the power supply first since it is one of the part that fails most, next to the backlight board.

TV won't turn on


I have fixed many polaroids, the problems is most of the parts are contained in one self contained control box. it sounds like your power board is not funtioning. contact polaroid and let them know about your problem and see if you can get a new control panel. the contol panel only has one connection and 3 screws to replace. hope this helps.
