SOURCE: Have an Element LCD model

Hi Jeramy.

These TVs are indeed re-branded Polaroid. You will not find the service manual under Element. You must find the equivalent Polaroid TV.

The Polaroid Flx-3202 is the same as element flx 3202 and 3212 the FLM-3237 is slightly different. Element were re-branded for Circuit City.
Polaroid service manuals won't be a great help, they are written to do board swapping. This TVs are cheap, and board swapping is all the repair that Polaroid ask the technician to do.
The service manual for 3237 is available on the Internet, but it is quite different, check if the two units have the same 37 pins sub, that is the part to be tested if PSU is OK, and there is no power to display (user upload Here Polaroid Service Manual-no t a great help). The other two are not available. Service manuals and bulletins can be ordered through Polaroid service contact.

When inverter and PSU are integrated, you check PSU voltages. There should be a control line from main board (or circuit). It may be passing through a sub board. If you have sound and LED on the AC main and DC-DC sections of the PSU should be OK, in DC-DC, check if there is power to the section going to the backlight (it is not a proper inverter). If that section has power in and no output, then the fault is likely in there.

If PSU is OK, a main failure is possible, but uncommon, the faulty part when PSU works well is the LCD panel.

Hope this will help.

Bye .

Ginko.

My element tv has no picture. (it can be seen with flashlight test) will a power supply repair kit fix this issue?


This is usually not the power board. the LED strips fail and you have 55 LED bulbs in the back light. It is not an easy fix because the display is glued to the bezel and if you don't take extreme care when working on it, you crack the LCD display.

My Element 46" tv ELEFT466 has sound, but no picture. The flashlight test shows a picture. I'm told this model doesn't have an LED Driver. Is it part of the Main Board? What should I replace? Thanks!


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

I have a Vizio E550i-b2 55 LED TV. I have no LED backlight. When I hold a flashlight to the screen I can see the images and I have sound. I was going to replace the LED driver? Thoughts??


U are on the right track - problem is caused by the board that drives the backlighting - the inverter board.

If you can get the number for the board it may be available on the cheap on ebay.

I have a sharp 37" lcd tv,model # lc37sb24u. no pix or sound, power lite comes on about 10 seconds then power and opc lites alternate on and off. thanks RON


This problems very common in Sharp LCD tvs.The Tuner signal board have problems,every times the power LED,OPC LED lites up,just push the power button on again,wait see if the LCD backlight lite up and works,not the Power lite and the OPC lite LEDS flashes again.You,just have to push the power button again,sometimes u have to push the power button at least 6 or 7 times to get the Power LED stable,and then LCD backlight,come on than the tv work.Not sure,but if the Power and OPC lites keep flashing,after u pushes the power button at lest 10 or 12 times,and the LCD backlight dosen't come on and the tv don't work.I think,it time to change the Tuner board is completely dead.I have a Sharp LCD tv, I do this everytimes pushing the power button at least 3 or 4 than the power LED stable,and the LCD backlight come on than the tv work.Not a plaw in the power supply like those capacitors in many LCD models tvs,but some included Sharp Tvs is the Tuner signal board is not very good in design,use the tv awhile the Tuner signal board have problems recieving the power to it Tuner board components.
