20 Most Recent Polaroid FLM-3734B 37 in. LCD HDTV - Page 3 Questions & Answers

You didn't state whether or not Polaroid sent you the disassembly instructions. IF they did, I apologize for repeating them to you, but what you can do is go to the following link to download a copy of the manual:

http://mikecampagna.com/Polaroid/

The second to the last sentence has a link to the manual. The sentence reads "... found in Polaroid's service manual which you can download HERE." If you right-click on the HERE word, then choose "Save As", you can save a copy of the manual to your computer. If you look on page 21, they describe how to take the panel off. This was always a bit tricky when we worked on this TV. You have to line up the cover with the runners on either side and then slide it up. The final step you do is to re-attach the 3 screws.

Inspect the power supply for bad caps with domed tops, it will get worst and may cause more damages if not fixed.

The whining sound that you have could possibly be due to a bad power supply capacitor.

I found this article to be very helpful in diagnosing the issue.
It is possible that the televison doesn't have those exact issues as described in the article, but it's a good starting point.

Power supply board is dead.Have dead capacitors that bulges up on it top,or puff up on it top.U know basic electronic's and soldering.Replaced these bulges and puff up on it top.Or tries wesite like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.After the power supply board is fix or replaced,the power LED indicator light on the LCD panel will not flikers anymore and u will have a solid green light all the times and get the power back to normal.

This tv have 1 or 2 long boards call a LCD inverter boards.These 1 or 2 long LCD inverter boards are dead.These 1 or 2 long LCD inverter boards help the LCD screen picture panel to have a backlight to produced a picture.Tries websites like Shopjimmy.com,Ebay.com to buy those refurbishes 1 or 2 long LCD inverter boards for the replacement.

Your TV is suffering from weak capacitors in the power supply and in the signal board. You will need an ESR meter to find the bad capacitors. Always use the same values of capacitors when replacing them.This is a common problem on the Polaroid TV. Thanks for asking and show a few hands of support!

Hi,
You have a standby power supply but you're unit will not power up because of the following reasons:
1. Make sure that the remote control is good, if so the trouble is internal.
2. Check the power switch button for open contact, bad solder joints.
3. You have a missing supply from the regulator section of the power supply.
4. The power supply has out-of regulation due to leaky capacitor.
5. Faulty EEPROM from the main board, faulty microcontroller.
The symptom is quite technical, I would advice you to measure each voltage output from the power supply to narrow the job. If you don't want to troubleshoot it because you haven't tools and test measurement, I would advice you to look for a proffesional to do the job for you.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

No,Tries tv unplug,replug it back like about an hour later.For the whole tv to do resetting back to the factory setting,now the tv should be working again.

Hi,

If you go to the Video Settings again where you altered the hue and saturation, there is an option for "Picture Mode". It probaby says "User" at the moment, but if you highlight this option and then use the RIGHT arrow key to change it to "Vivid" or "Hi-Bright", this should undo all of the changes you previously made and give you a good base to work from when re-adjusting.

There are no "correct" numbers as it's down to your own preference and varies according to the lighting conditons in the room where you use the TV. You should only ever make very minor adjustments to any of these settings and check the picture on the screen after making each adjustment and before making any others.

Hope this helps - please let me know if you need further assistance.

I have polaroid flu 3232. There is no power

Check the power supply for busted/expanded/bulged capacitors is the first thing I would do. If you dont have experience with electronics you may want to take it to a tech shop as the voltages/amperage can kill you if you dont know what you are doing....

Thanks,
Michael

The T-Con board needs to be replaced. It set at the top/center of the set. I've enclosed a picture of what they look like.

either inverter board or t-conn board this is the small board at the top middle of set.

check youtube.com they have videos on how to fix just search for your model

Probably due to a bad solder connection on one of the inverter board transformers. If the problem persists it will burn a hole through the board. An open transformer will cause the set to shut off. This should be repaired by a qualified technician.
