My friend recently gave me 2 Absolute HM65 headrest monitors and i tried testing them b4 installing them and i hooled up the red wire to my inline fuse holder that i have on the battery and the ground directly to the negative batter terminal, the unit turns on and it displays the picture but the back light of either two monitors wont turn on. Idk what it could be i was starting to think that maybe it wasnt getting enough power but i dont know... If anybody knows please help or point me into the right direction. thanks

yes the led backlight for whatever reason is not functioning and that is the root cause of your problem. Unfortunately to find a replacement led backlight is tough as the backlight is normally fixed with the lcd panel and has to match the voltage and all that stuff with motherboard. and if that doesn't match you might short the tv itself. this case is as good as getting a replacement lcd panel.
Those cables can go bad easily. If you have a meter and know how to use it, try to test continuity on each pin. If that isnt the answer, then either the input of second monitor is faulty, or output of main screen.
you can try to use a y splitter. the problem with that is the receiver will not give you enough "power" to power up the headrest. You will probably lose picture quality. There are amplifiers that can be purchased that will have extra outputs for video, this would be your best bet. It will give you great picture quality.
Ur LCD inverter backlight board is dead.Replaced this LCD inverter backlight board will solved this problems.Tries Websites Shopjimmy.com,Ebay.com to buy a refurbish LCD inverter backlight board for the replacement.The board is a long in shape.
Let me guess, you have a pioneerr dvd headunit a video amplifier and 2 headrest correct.
Now connect from V/A in at the headunit to V/A out at the video amp. Connect V/A out put from #1 headrest to #1 V/A in put at the amp. And V/A out put from #2 headrest to #2 V/A in put at the amp.
Try plugging the external VGA adapter to an external monitor. If you see your desktop or post boot on the external then most likely the lcd screen is bad or you may get lucky and it just be the "backlight tude" Either way I would replace the lcd screen with a new one if the backlight is already shot. You can buy a new screen for around $99 and they are fairly easy to install. Again confirm you have picture to an external monitor b4 you buy a new screen.
When you include addresses like A2, C10, F15 they are relative addresses .eg: If you have entries like: in B4 you have saturday in C6 you have the formula =FIND("a",B4) .....the answer is 2 B4 is a relative cell address, because if you copy the formula across the row, OR up/down the column, the formula changes and the answer changes To make it an absolute address you have to type a $ in the cell address. If you type the cell address formula as $B4, it means wherever you move to or copy the formula the B will not change If you type B$4 the row no 4 is ABSOLUTE or fixed. $B$4, both column B and row 4 are fixed. If you move the formula anywhere the cell reference will not change. Summary B4 is a relative cell address $B4 is absolute address (B is fixed) B$4 is absolute address (4 is fixed) $B$4 is abso;lute address (Bis fixed, 4 is also fixed) Hope this answers your question luciana44
