Question about Polaroid TDA-03211C 32 in. LCD HDTV

1 Answer

I have a Polaroid TLX-04240B It comes on and Displays the Polaroid logo, then it goes to a black screen with the HDMI1 input box on the top right hand corner. THis box eventually disappears, leaving me with a black screen. The menus seem to work. But the signal only dispalys a black screen. When no source is connected, it will display the blue screen stating no signal. Apparently it is getting the HDMI signal but unable to display it? I have taken it apart and inspected the capacitors, which all appear fine. Any ideas troubleshooting ideas? (I'm used to working on laptops, but have little experience with TVs :)

    The HDMI cable works fine on another display. I suppose it could be an incompatible cable, but that isn't very likely. There are only 2 HDMI inputs on this TV, and I think they both use the same hub, I have tried both of them, in any case.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

I have Polaroid 42" TLX-04240B


That indicates that it could have a power supply problem or a back light power problem. Some part is working when cold then failing when warm. You need to check to see if it is just the back light. With it on and after it goes dark see if you can make out a ghost like image on the screen. You will have to get quite close and near the edges to start to see any images. If you can see this and it is a moving image ie the tv i still on but just no bright display then it is your back light and most likely the back light power board. If it is actually shutting right off then it is your main power.

If it is the back light and the board is a separate piece on that model the part should be $40 to about $75 If it is the main power then you could be looking at $150 ish for a separate power module but if it is on the main board then you are talking about more money than a new tv. Both would be covered under warranty so check to see if you are covered. You can get the parts from any of several on line stores. Just do a search for Polaroid TLX repair parts. These should be cheaper than getting them from a dealer or repair depot if they are available.

Polaroid TLX-04240B going to a black screen after running for 2mins. Any ideas on how to fix this?


open the black plastic panel and the aluminum panel which has 3 screws each in the back of the tv.
look at bottom left corner of top board. to the right of the red led light,
there's these four white small switches. turn the bottom two switches to "on" and tv should be working.
It's very simple to fix the problem to everyone.
My tv capacitor was not the problem.
I hope this will help everybody.

I have a polaroid 42 inch flat screen and the screen is solid blue when i plug my cable in it is black I can here sound but no picture it is a 2007 module tlx-04240b


Make sure all the connections are correct, a "blue" screen indicates no-signal, black indicates some type of signal is getting to the tv. good luck Julio milleniumtvsvc@gmail.com
