I've also seen fixes for the 36" Polaroid tv's for switching out the 1000uf caps. I'm not seeing these on the board. Are they hiding under the heat sinks?

Thanks again.

Hi Guys,
Your TV haves a image on screen thanks to a backlight on your LCD panel, that backlight is created by at least 7 or 8 LCD Lamps for Small Displays, to maybe 20 for big ones. Now the issue could be only in two different ways:
A) Your image is only dark side to side in a rectangular area, this means that one or more lamps in that area are not turning ON, to resolve it you need to check if that lamp is provided with voltage by the connector of the lamp on the voltage inverter board, and it haves to be the same reading that the other lamps, if it does, then that lamp is deffective.
B) There is no image on screen, most probably one of your 2 voltage inverters (there is a left one and right one) is damage, you need to change the voltage inverter.

Hey all—So I have unsuccessfully been able to locate the 1000uf Caps on the boards for my 42" tv. People think this is the fix—but it's not—it's for the 36" tv's only.

I fixed my tv by playing with the Dipswitches.

I have read everything I can find on the net about this problem for Polaroid TLX 04240b TVs (most, like mine, bought from Wal-Mart on Black Friday after Thanksgiving). I thought I was on a hot lead when I changed the 220uF 450v capacitor, but I still had the same problem. I saw a short post from somewhere on the FixYa web site (sometimes I can find it again and sometimes I have trouble locating it) that said someone flipped a tiny switch on their circuit board and the problem was gone. I did the same thing and my set has been working fine. They had said their set was on for over 8 hours two days in a row when they posted. The other night my daughter left our set on over night for 20 hours and the picture still was working great. If you look through the top of the set when the picture is on you can see some white light at several locations, when the screen goes blank the white lights go out and a red LED light can be seen. If you take off the plastic cover on the back (3 screws) and then take off the metal cover (3 screws) this red LED light is on the upper circuit board in the lower left corner. Just a little to the right of the LED light is a small switch block that has 4 tiny white switches. I turned my set off and took the bottom switch (#4 and had the letters BURN by it) to the right "ON" position, turned the set back on and, so far so good. PLEASE NOTE!!! I know almost nothing about how transistor circuits work. I have no idea what the switches do or what long term effect this might have on the set. The set was only good as a paper weight before so even if this only fixes the set for a short time it was at least worth a try for me. Does anyone know what those switches are supposed to be for?

Dude, this is a joke. Im just going to help GDP by getting a TV tech to fix it . Yes im going to get ripped off and maybe pay an extra 100 or 2 but my TV will be working instead of haveing a mess in my living room . Good luck guys on this CRAP TV. I will NEVER buy any PLOROID product again :)

^^ I completely agree with you—my wife and I were at Wal*Mart on "black friday" when we bought it. It was a spur-of-the-moment type of thing where she wanted it. I had no time to research Polaroid TVs—hell I didn't even know Polaroid made a tv—but the price was right. Whether it'd work 2 years or 10—we brought it home.

So far the tv has been working flawlessly with the DIP Switch setting fix as described above. In my situation all of my switches were set to OFF by default. I set the bottom to with setting "burn" and "WPMW" (if i remember correctly) to "ON".

Again, like the next guy I have no technical training—I'm only a designer. :) So far I'm enjoying my tv working again—if it DOES act up, it'll be the end of it.

However I will never buy a Polaroid tv again.

i too had the same problem. i changed the big black capacitor mentioned but still had the same problem. after giving up for a few months, i checked back to this post and i tried what cdmc mentioned. i switched the two bottom switches to on and it's been working fine. i still need to figure out why the picture quality is not up to par. the pix is like a blur on the bright colors. if anybody knows this problem and its fix, please let me know. thanks....

Made mine work!! Finally after 3 whole months in the repair shop, I had to go get the TV and repair it myself with no cost at all. Turns out I just did as cdmc mentioned too, switched the said switches to the on position, and problem solved! Give it a try, you have nothing to lose, and lots to gain. My TV is working great, thanks for the help everyone, especially CDMC!

This is a lot of great info for the future. I have had a Poloroid 42 inch plasma TV for 1 1/2 years now with no problems. I would encourage that anyone with a modern HDTV protect thier investment with not only a surge protector for lightning strikes, but also a voltage regulator to eliminate voltge surges/spikes ans well as brown out issues. Probably 90 of TV failures can be traced back to power surges and lightning. I bought a 600W regulator on-line of about $35 and bought the surge protector the regulator is plugged into for about $15. Cheap protection for expensive equipment.
