When it have this kind of error is a problem of the powerboard.
Anyway you must open it and look at the all capacitors and if are them inflated, if them are inflated must change them.

But can be a problem with inverters... control the transistors - MOSFET on the powerboard.

Good luck!

This does not seem to be a power supply issue but rather an issue with the backlight inverter board. When the screen goes black, take a flash light and focus it on the screen from a close distance and several angles. See if you notice a very faint image. Try changing the channels to make it more noticeable. Try it and let me know

When my computer boots up sometimes the screen is ok, but more often the screen fades and goes black. If I switch the monitor off and then on again the screen shows the icons etc for about 2 seconds and...


This could be that the screen topback light or bottom back light is bad or the inverter.
the topback or bottom back light could also be seing as the flouricent of the screen that light up the screen to enable display visible.This top back light or botom back light as the name implies is positioned at the top and bottom side of the screen.It takes an expertize knowledge for one to be able to change the flouricent when comfirms bad.The same is applicable with Inverter.

Polaroid 4241-TLXB wont stay on


I think I may have just solved this issue. Remove the back covers and turn the tv on until it the screen goes black. There will be a little red led that will light up when the screen goes black. right above that light there is 4 little swiches, the bottom one is labled BURN. Switch that one to the opposite direction. I don't know how but mine has been working for a couple days now with no issues. GOOD LUCK!

I Think NO expert can help this problem because it free answer


I think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know
