I changed the capacitors on my polaroid lcd tv. It fixed the problem with it not coming on, now I get a picture and sound, but the screen is blue or in black and white tone. If I change the setting to warm, it goes orange, natural is blue, etc. Could I have done something wrong when changing the capacitor? Or is this a different issue? It wasnt doing this before it went out.

I would first check the power supply. Check the main fuse, if is blown and there was no power surge from an external source, the supply board has some serious problem. If the fuse is fine measure the output voltage of the power supply board. Check for any swollen electrolytic capacitors, they are the number one cause of every LCD failure I have come across. I just fixed a Polaroid FLM1514 which has a 2956C Ver 2.0 power board driven by a Fairchild CM0765. Turns out the VCC capacitor was bad and not even swollen, sowpped it for a 47uF 50V and presto.
You have a bad capacitor or two in the lighting of your LCD screen. I have not worked on this particular unit. I have had a smaller version of this TV. On the smaller version there were two capacitors in the power supply. The transformer that lights the LCD panel ,yes, is in the power supply.There were two of them and I think the values were 35 volts at 1000Mfs. I hope this will clue you into a fix. Yes, I really think you have a couple of bad capacitors. If you pull this TV apart, by all means inspect all the capacitors in the signal board (has the RF connections and all your RCA connections). You will find several bad capacitors by now. I do repair TVs, so this is good advice for repair. Thanks for asking and show all hands of support!l
You have weak capacitors in the power supply and the signal board. I have not repaired this particular unit, but have experienced this with other Polaroid TVs. You will need a TV tech to replace those capacitors. It is a very time consuming task and requires patience and much care to remove the capacitors. Tell a tech that they must be very careful when they remove a cap in the signal board, as they can peel off a pcb trace. In most cases they replace the signal board, but the capacitors can be replaced! Thanks for asking and show a few hands of support!
It has 2 blown capacitors in it. Mine had the same problem. The capacitors are located at EC17 & EC18 on the top circuit board inside the tv. They cost about 1.00 a piece. You can get them at DigiKey.com. It is very easy to take the board out and have someone soldier the new ones in and then put it back together. You can fix it for about 40.00. Hope this helps. Do a search on line of what the capacitors look like........
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...........
I fixed my problem for $3.44 at Radio Shack.
This is a common problem with this model.. go to you tube and search for polaroid 37 lcd repair, there is a video showing which Capacitors to replace. there are two, i bought 2 1000uF 35 watt/volt capacitors. you have to take the back panel of the TV off, remove the power supply board, and de-solder the two CAPS. install the two new CAPS, re-solder them, put the TV back together and enjoy. Radio Shack part #'s i used 272-1032.
I suspect you have a bad set of capacitors in the control module. This problem usually starts out as a high pitched noise but can lead to the TV not turning on. Please see the link below, posted by StivO. It gives step by step instructions on how to replace the capacitors. This is a very inexpensive fix.
I had the same problem with mine. Replaced the capacitors and now it works. When you open the back of the tv up, the problem is with the 2 capacitors on the upper left of the top card. Mine didn't look damaged except for a very, very slight bulge on the top. If you've never soldered anything, you might want to take it to someone who has, otherwise, it's a pretty simple fix. I was surprised I could do it so easily.
If the warranty is still good, make Polaroid replace it. They make shoddy products and should pay for it. And never buy another Polaroid again.
