Top 20 Polaroid FLM-3732 Television - Page 2 Questions & Answers

Check your fuses for starters. If they are blown, replace them. If they blow again, you have a problem in your power supply.

Hello,

This model is know for having power supply issues. We have a step by step repair guide posted on our web site at http://www.ccl-la.com/blog/index.php/visco-vsc-37v1-no-picture-lets-repair-it/ If you can solder then you can repair your TV, if you don't want to do the repair yourself we do offer a repair service.

That set is on youtube and they show how to fix just search

The humming/whinning sound is from the power supply module and it will get worst (bad caps).
The lines on the screen can be caused by poor DC from power supply, or failing T-CON board, main baord, or worst case the LCD panel.
As you can see you have multiple problems so it may not be practical to put a lot of money into it.
See the pictures of the boards and prices.

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Capacitor kits: http://lcdalternatives.auctivacommerce.com/ he can make you a set of caps for you. Or www.digikey.com just make sure to use caps with low ESR, 105c rating such as PANASONIC FM or FC series. Parts: www.shopjimmy.com Please post back what you find. Please leave rating if it helps.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

Always get your drivers and specific software from the manufacturer of your Laptop, Notebook or Desktop. They are usually free of charge.

If you were to log on to the manufacturer's web site, usually one is able to download if available, by model number, All available Driver downloads as required.

If the driver is not available, perhaps your manufacturer does not support the OS you are installing.

This is the best way of ensuring up to date drivers for your system and they are free of charge!

I hope this helps.

This can be due to two reasons
1. it can be a failure of any filter capacitors on the audio section and is not stabilizing the output or the preamp stages.
2. The SIF- sound intermediate frequency is shifted and so does not coincide or align with the video signal. This can be mismatch/mistuning within the circuit or a failure of the processing IC/coils.

Hi

Most GE ovens require that you pull out the inner oven liner in order to fit the new seal.

See also this manual with pictures.

R0804-0901 Part number for power supply. Most likely your problem. this is 74.95 from DM Discount merchants. ALSO you may look for swollen capacitors on board and replace as needed. This requires soldering.

Have you tried the capacitor replacement trick here: http://www.fixya.com/TipsAndTricks/ThreadView.aspx?thid=741402 ? Use the method described (two places - look at both) to open the back of your TV. Look on the upper board (the power supply - where the 110 vac goes) for damaged capacitors as witnessed by their bulging tops. If they look ok and nothing else on the board is obviously damaged, I would go ahead and replace the three capacitors there. Two located near the center top of the board are 1000 micro farad 10 vdc electrolytic and the other right below the first two near the center of the board (a bit larger) is 1000 micro farad 35 vdc. Replace them all with 1000 micro farad 35 vdc (or wvdc) electrolytic caps - you can buy them from Radio Shack for $1.50 or so each. This assumes that your FLM-3732 is similar to the FLM-373B that I have. Good Luck!

PS the Main board etc depends on how it actually looks

That can be the T-CON board, main board that send the LVDS to the T-CON, worst case will be the screen itself. You can try reseating the ribbon cables between the LCD panel and the T-CON board to see if it help first. Post back what you find.
See example of bad T-CON/LCD screen in my guide.

Check youtube they have videos on this tv just search

yes in most polaroid its in the plug area where you plug 120v cord to the tv there is a black piece that has a fuse on it and you pull it up and the fuse is in it. also on the power board

That situation clearly indicates that no signal is coming to the set in its present setting. Have you checked to make sure that the tv's input is set on the right input setting. Mine always defaults to "Antenna" which drives me nuts cause I get that big blue screen with "no signal". It seems to do that at the slightest provocation, too. After 5 years, I still have to think twice before checking it. If that is not it, make sure that the cables are plugged in. If that doesn't fix it try another type of input such as HDMI or S video, composite, etc - one that you are not using. Don't forget to switch the input to it. Good luck!

You have bad filters in the Main Logic area

Please refer to the link below for the manual and schematic diagram of Polaroid FLM-3732

Hi,

Welcome to FixYa.

Please elaborate your problem providing us with more details.

Thanks for using FixYa.

Your speaker might have bit the dust, but it is more likely that the TV thinks that you are using another sound system. Do you have something else hooked up to it as well? I would try to disconnect everything but the tv input to see. If you get no sound with everything else disconnected, the tv's speakers are probably disconnected somehow. Is there one of your menu settings that shuts off the set's speakers?

If you still are having problems with your TV after trying the following repair page: electrolytic capacitors in the power supply are probably failing: http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen Then you should just write the TV off because another 37" Toshiba or Panasonic is less than $600 and that part is expensive! The part number might be down in the posts for this problem as well.
