It may have power supply, T-CON, backlights inverter, or main board failure. In any case, it will require parts.
Please read below first.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having. If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on: Basic LCD monitor and TV troubleshooting guide: http://www.fixya.com/support/r5093881-lcd_flat_panel_tv_troubleshooting_guide http://www.fixya.com/support/r6150077-basic_lcd_monitors_troubleshooting http://www.fixya.com/support/r7406380-tv_training_manuals Failed TV and Monitors: http://s807.photobucket.com/albums/yy352/budm Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague Parts: www.shopjimmy.com Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps. Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series. Please post back what you find. Please leave rating if it helps.

First place to start will be the power supply module, right now the standby 5vdc is working but not the rest.
Please read my guides so you will at least know what to look for inside.

you seem to have the incorrect code to the tv this is not allowing you to turn the unit on try the main override switch at the side. appart from this you will need to keep scanning until you get the correct code

let me know if you need further help

Could be the input selector board not changing inputs. Presumably you have pressed the input button on the remote? What happens? Power down completely, remove mains plug wait 15 mins power up and try again. Also try a reset in the menu.

First turn on and check with flashlight 2 in. from screen and see if there is a picture. If no picture then open back panel door by taking big black screw out of middle and 2 screw at bottom of panel and slide panel downward, pull off and unscrew metal plate and you should see bad caps in this set, this is what have to be replaced.

First place to look will be the power supply module, look for bad caps, fuse, burnt out parts.

do you have the red light or blue, if red and don't come on then the problem is in your power supply, sometimes you can take back plate off and see the bulging caps and change and get set back running.

Check your remote control battery - also, test the remote control by using my Tips I wrote.

The first thing I would do is check that the capacitors are not bulging on any of the boards in the machine. For reference look at: http://www.fixya.com/support/r741402-polaroid_flm_373b_lcd_tv_black_screen If you don't see any bulging or otherwise clearly failed capacitors, then I have no idea why a portion of the screen would be failing like that. Sorry.

Hello

This is a decent price on ebay

at least I think its a decent price...

best of luck

Looks like you have accidentally spilled some liquid on the screen, however now the screen itself would have to be replaced and that is not usually cost effective.

check supply bored and or change capacitor in it

Controller IC3 in power supply board. best to have a professional tech. look at it.

Call your homeowners' insurance agent. Seriously, if the set is worth more than your insurance deductible, you will want an expert evaluation on whether the set can be profitably repaired so you can make a claim if necessary.

Was the first fuse blown? Did the second fuse blow? If the answer to both questions is yes, then you have a fried power supply switching transistor - at a minimum. You might even see cracked or burned parts on the board that has the fuse on it (look at the parts on or near the finned metal radiators). Lightning typically damages a number of parts. You may find it cheaper to replace the entire power supply board, and hope the rest of the set isn't damaged.

If both fuses are good, that could be worse news, because that implies lightning got in through the antenna/cable input and zapped the main circuit board. This is the second-most expensive part of the set after the LCD panel.

A suggestion for "next time": if a TV set blows a fuse, get the problem fixed first before risking a new fuse on it. It's rare that a power surge blows the fuse without also breaking something else. The fuse is intended to minimize damage and prevent fire in case something in the TV shorts out or the surge protection components are unable to handle a high energy pulse on the power line. It's not guaranteed to protect the set from damage.

First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board. if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that.

Power supply board have problems,not giving the tv the wright voltage anymore.That the board,where the power a/c cord plug into it.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

I have not repaired this particular model. But I have repaired another polaroid flat screen TV. I can tell you for sure, the biggest problem here are bad capacitors in the signal board. You may find 15 or 20 bad caps. On the power supply there may be a two or three caps that need replaced as they will be weak but not real bad. Yes,the majority of the caps will be found in the signal board. You will need a good capacitor checker to locate these. It will require patience and skill to remove and replace these caps. I cannot say enough of bad capacitors in this TV. Find a TV tech to help you! Thanks for asking, show me a few hands of appreciation. This answer is your best effort for repair!
