    The set has a bad board in it but to determine which board is bad has to troubleshooted by taking voltages on the set. You may need a tech to look at it, or are you able to do it?

I have a Emersom EWL3706 37in led tv. You have to turn it on 3 or 4 times before it stays on. After about 10mins it shuts it's self off. Turn it right back on and it stays on for about 1min and shuts it's...


Start voltage problem. In some cases, it can be repaired. In most cases not. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. 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 power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

I have an element 37in. flx-3710 tv. lately whwn i turn it on the screen stays blacks and flickers for a few minutes untileventually the picture appears.however the picture is either washed out or so dark,...


ldq781, I think you or electronics technician should investigate the units internal "switch-mode-power-supply/cold cathode-fluorescent lamp electronic ballast circuit(inverter) for "failed" "swollen" electrolytic filter capacitors and or "poor quality" soldering of the electronic components to the copper foil traces of the printed circuit board(power supply board) The first thing to do is visit YOUTUBE for video clips of lcd monitors being repaired for these typical types of "failures" which are most common to both types (monitors and lcd tv's) After you do your research then return here and leave additional reply if you still need help. 12fixlouie

Ok.... I got a new power supply board and the tv is still doing the same thing. (Sharp Aquos 37in LC-40C37U) So if it is not the power board then what could be wrong with it. I'm getting no power and only...


The pattern of the blinking is a code. If the power light is blinking by itself once per second or thereabouts it could be loose connection to Inverters, reload firmware, Inverter Unit or LCD Panel.

If my Sharp Aquos 37in LC-40C37U tv needs to be reset how would I do that? Not getting any power, only a green blinking light. The power supply board checked out ok.


Blinking light is an error code. Count the blinks before they repeat. Check your manual in the troubleshooting section. If you can't find it, contact a Sharp service center or try and get a service manual. Reset info is also in the user manual but you can't do it if your set doesn't power up. Are you sure about the power board?
