    same problem but the picture does flash on for asplit second when the on off button on the front is switched on.

    this indicates the backlight is working but perhaps the power supply may be faulty. I have dismantled the whole thing and checked and moved all connections, but after re-assembly the same problem exists.

  • karlzinn Mar 04, 2008

    for all inputs no picture, only vertical grey bars (which don't change when I change inputs), almost like a "test pattern" but sometimes shifting in shade of grey.   sound is ok.  I have turned power off and back on several times.  I have left set on for an hour.

  • allenc5782 Mar 13, 2008

    Mine is white too. if i let it warm up a while it will turn on but then goes off. a piece on the power supply is buzzing. I took it apart and found no noticeable flaws. If its cheap enough try the power supply, I have a polaroid and its easy to remove. but theyre also cheap tv's.

  • inc1872 Oct 20, 2008

    same problem here . I bang on it any were and the screen flashes .
    I bet since I've had this TV for 18 months now that there is no warranty , that you can expect to pay $550 for a TV to work for only 18 months,
    So I'll wager that something inside wiggled loose and with no warranty I think I will pull it apart. I'll let you know

  • Anonymous Nov 05, 2008

    sane problem - replace backlight? although it woks when you first turn the TV on (for a few minutes) - replace ballast or the like?

  • missy trapp Nov 05, 2008

    I have the 26" LCD with the DVD combo and I just literally bought it yesterday and we set it up and starting watching a dvd. As soon as I paused the dvd to get something, the screen went white and you still got audio. We've since then had it happen 3-4 times in the middle of the movie. What would cause this? This Tv is brand new!

Check the capacitors on the main powerboard. They are cylindrical and the tops look like they are a perforated X. If the X has popped up or broken than those capacitors need to be replaced. Also, compare your powerboard with one for sale on E-bay and note which capacitors have been changed (usually a different color; factory black; changed blue or orange)

I did this for my Akai 27" LCD TV and it works now. I changed 3 capacitors that were rated at 16v/1000uf to 24v/1000uf. Cudos actually belong to a Mr. Brown who I read about in a forum somewhere. Thanks, Mr. cost me $5 to repair my TV rather than $135 for a refurbished powerboard.

This might be a possible solution instead of a complaint. First for those who has black screen and sound. Go to website:, you may have to sign up. In here it will tell you that with this symptom you may very well have a defective inverter. It even tells you that you can change it yourself and doesn't require a very skilled individual to tackle it. The only problem is the backlight inverter module costs 179.00 bucks and thats the problem for me; just waiting to gather the cash so had not tried this fix myself. Good luck for those of you who are going to jump into this one.
ps. If this is a solution for you, please email me to let me know, it may or maynot save me some cash or headaches.

Sound but no picture

The first thing that comes to mind is that the brightness and contrast or turned all the way down. See if you can't turn them up. Otherwise it may be the backlight inverter or backlight itself. Most likely the inverter, sometimes you can tell by looking really close to the screen, if you can still see a faint image then the inverter needs to be replaced. Probably a job for a technician but that depends how comfortable you feel opening up the TV and ordering parts online.

Good Luck!

Audiovox model FPE3000, has sound and picture but

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.

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
