The Polaroid FLM-3710 is notorious for bad capacitors on the power supply board. There are six 680 uF 35 volt caps and three 680 uF 25 volt caps. When they go bad, they swell and the tops bulge upward. Also, there are three 22 uF 50 volt caps that go bad, but they do not swell. So you can not tell just by looking at them. If you see any bad caps, I would suggest replacing all twelve of these caps.
If there was a power surge, it could blow out anything. Check the fuses and the full wave rectifier.

The power supply fuse should be next the the ac input plug on the power supply. It should be a long cylinder type fuse, probably a T6.3AH/250V. You will want to replace those caps ASAP

It looks like your power supply might not be providing enough current to get the LCD to power up. This LCD needs about 3 to 4 amps to work properly.

It sounds like you have tried everything I have been able to find on the web......Have you Registered your TV with Polaroid yet? Because if you haven?t you can make up the few months your past on the warrantee.....I would go and Register and then call on the a bit fishy but it works...In my opinion they should just warrantee it for you. (being so close to the end an all) ....I have had great success when I have call the manufactory directly to see what they can do for me......don?t talk to just any one ask for the manager of customer service or the manager in the warrantee the very begging of your call.... here is there information if you didn?t have it already Regional Headquarters: Polaroid Corporation Corporate Headquarters 300 Baker Avenue Concord, MA 01742-2131 Phone: +1 781-386-2000 Good Luck and be assertive but not an *** on the phone.......I find that when I?m just strait up honest with them it all works out....If it doesn?t try the Registration thing?Let me know if this helped cbinny1

SOURCE: I need help fixing a Polaroid FLM-3232 w/o power

I do not know what your problem is as you do not even describe a problem, but I dare say capacitors do not need to be bulged to be deffective.

Usually the ones closest to heat source are the ones to dry first; bulging can be result of a too strong current running through them too and not neccessarily related to heat.

Usually they are large and close to the connectors that carry power from the power board to other internal boards.

Other capacitors may also be affected, of course.

You can try your luck replacing them in order, bring the TV to a specialist or start reading the theory of repairing SMPS - you can find it online, an excellent read if you really want to get into it.

Diagram where fuse is in the polaroid flm-3701

There is a fuse on the power supply board. It is labelled F1. It is a small cylinder near the AC connector. The F1 fuse is 5A 250V. How ever, capacitors are more likely to fail on this television.
The Polaroid FLM3701 has a problem with capacitors failing on the power supply board. If enough caps go bad, you will get no power. Not even a power light. Any capacitor that is swollen is bad.

I've got a Polaroid FLM-3701 LCD TV. I have had the TV over 4 years and it's worked great. Recently it's starting to shut itself off. I say "shut off", actually the picture goes off, the power...

It may have dying power supply due to bad caps, this is common problem with 3+years TV and monitors.
Please see my basic troubleshooting guide here:

Capacitors kit: he can make you a set of caps.
Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

37" LCD Monitor FLM-3701 While I was watching it went out as if the power went out, but the cable box was still on. There is no indicator light on the monitor. I have unplugged and plugged using...

Hi and welcome to FixYa

Initially, the described problem with the Polaroid FLM-3701would indicate a power supply problem. While this could be nothing but a fuse that blew, a faulty cord / plug or even no power to the outlet, it could also be caused by failure of the power supply to fully turn on either:
  • auto-protect has kicked in to prevent further damage;
  • the power supply itself has faulted and could not produce sufficient voltage to operate the unit.

This is then a hardware fault and would require that the unit be opened up to effect repairs.

Options then are:
  • consider a DIY (do-it-yourself) repair if and only if comfortable working with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe practices with electrically powered devices. Access to a Service Manual or at the very least, a schematic diagram would be a necessity;
  • should you be uncomfortable with a DIY, perhaps your best bet would then be to consult with and/or seek the services of an authorized Service Center or a qualified professional.

Offhand, while test points, voltage checks and repair steps could be provided, it is necessary to use a multimeter to determine voltages at certain pins while the Polaroid is live. Is a DIY being considered?

Good luck and thank you for asking FixYa.

Where is the fuse in a 3701 LCD Polaroid TV/Monitor

In the Polaroid FLH-3701, the fuse is located on the power supply board, next to the AC power connector. It is a small black cylinder. It is labelled F1. Value is 5 amp, 250 volts.
A fuse does not blow for no reason. Most commonly a fuse will fail because of a short someplace on the board. I have this same TV. The fuse blew. The reason was transistor Q6 had shorted. There are two identical paired transistors on the output side. Q6 and Q7. They are both Infineon 11N60C3 MOSFET transistors. Check those for a short. There may be a burnt smell.
More commonly, this TV will fail because of bad capacitors on the power supply board.

Connect from wall cable to tv.

you are trying to use a monitor as a tv, you will need a tuner to get a pic, use a cable box or digital to analog tuner to get something

Element FLX 3202 no power

This was the same thing that happened to me. When I took it apart and checked the power supply the capacitor (largest on the board) was blown. I called Element Electronics, which turned out to be Polaroid, and they sold me the entire control box assembly for appx $115 with a $100 core deposit to ship my old assembly back. My core deposit was credited back to my account within 2-weeks. BTW, when mine went out I had no power light on at all. Lastly, If you have questions about doing this yourself let me know, while I'm no electrical engineer, I did a ton of research trying to solve the problem.
