Audiovox FPE3000 - no pix, has sound.
Either the back light (a fluorescent) has failed or the inverter that furnishes high voltage for the tube.
I'm pasting my suggested procedure below-
If it is affecting video only, the display's fluorescent
back light or the power supply for it (inverter) is probably at fault and without some
technical background and a couple of test instruments, you will not be able to
do the repair yourself.
What you can do though is; unplug the set, let it
stand overnight or at least several hours, remove the back panel and look for a
smaller separate board with some larger components on it; it will have ferrite
core transformer(s) on it and some medium-size capacitors which are cylindrical
and mounted vertically to the board.
Before touching anything inside, especially on either
board, allow several hours to be safe since the larger capacitors in the main
power supply can hold a painful voltage charge for some hours.
section most likely to fail and cause your problem will be one that you see
associated more with the display than the incoming AC line; the latter is the
main power supply and its failure would result in no sound or video.
If you see signs of overheating such as discoloration of
the board material, it may not be repairable but if you can find a part number
on the board, you might be able to buy the power supply from the manufacturer
and install it yourself.
typically connected with non-interchangeable connectors.
If there are no signs of heat damage to the board, there
may be companies offering to repair it as a subassembly instead of repairing
the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since a
failure of the fluorescent, while likely to be less common, is the second

27 inch lcd tv/mointer
Did you replace the fuse with the same rating? some other component- possibly a capacitor may have caused your problem-either way your 5v stnby light now goes off and still no power to the tv its your power supply- was the tv still plugged into the wall when you replaced the fuse?

if it was manufactured before 2007/8 then probably not- good way to check is to run an auto scan in the set up mode- if the tuner is digital it will find the 7-1 7-2 etc digital channels that have been placed in between the analog stations

Have audiovox fpe3000 no pic or sound.
First check to see if you have your 5v standy - a red or other color light should be lit on the front of the tv- also check to see if you can hear a clicking noise -comes from the relay on the main powersupply- listen as you press the power on button-if its totally dead- check your power supply fuse 1- usually a 3.2 a 125v- depends on power supply if its no good- some other component on the board may have caused it- either way need another power board

Plv16081 same problem
I would say backlight inverter board or power supply. When it goes off, shine a light at the lcd and check if you can still see the image. If you can then it's the backlight, if you can't then it's something else like the power supply.
