    Same problem, same symptoms. Picture went to black suddenly, but still had sound. Hit reset on the remote and sound went too. Cable is working (using spare TV now). Sanyo TV is slightly more than a year return/exchange.

    My set is having the same problem. The set was given to me recently. The previous owner said they were watching it and it just suddenly went off and would not work after that. I have sound and there is a brief flash on the screen upon powering up, then screen is dark. I checked the main power supply board and everything seems ok, but I do not appear to have high voltage present at the CCFT tubes, although I have 24 volts present at power inputs of the CCFT driver board. The set is not that old, previous owner said it was still under warranty, but they misplaced the sales receipt.

    I am having the exact same problem. We were watching our Sanyo DP32746 one morning, then the screen went black. We still had sound, but the picture never returned. The manufacturer's warranty just ran out 2 months ago.

    I already called Sanyo for help, and they only said to try and reset the TV - no luck. We then tried unplugging the unit for a few hours - still no luck.

    Have the exact same problem with my Sanyo. I do not buy the explanation that "the screen is bad". The flash of light is the ccfl backlight bulbs coming on for an instant and going back off. I believe it is one of the circuit boards causing the problem. Probably the inverter board but I have not discovered a way to test the inverter, short of replacing it. I doubt it is the bulbs themselves since they actually come on for an instant. This tv is cheap and Sanyo ought to be ashamed of the piece of junk.

  • ANDRE365 Jul 26, 2008

    Thanks for nothing Sanyo! Same problem here as everyone else that bought this big black hunk of junk hanging on my wall!

  • badfc Aug 01, 2008

    Exactly the same problem. About half the screen flickers when I turn it on, then no picture. Does have sound though. I'm an organized person, but can't find my book or sales receipt for this purchase. I know I haven't had the tv that long.

  • Atwima Sep 04, 2008

    Please, I bought a Sanyo TV in March, 2007 but now there is sound but no pictures. When I switch it on there is a flash of light across the screen and then the scree becomes black. The tv is the CR tube type. Please , what is the ploblem?


  • SullSki7799 May 11, 2010

    I have the same exact problem on the same model no. I do feel fortunate enough that I have gotten three years out of this TV but the sound is all there and the picture is BLACK. I asked around and called Sanyo and everyone seems to think it is the replacment lamp. Sanyo stated it is not the lamp that is going to cost, that in itself is cheap ... it is the labor, well according to some other people, it is like changing a lightbulb ... pull the one out and replace it (without touchingthe bulb itself) ...

    Still researching this however ...

    Hopefully this will lead people in the right direction of where to start looking. !!

My DP32746 went black just like everyone else describes after 16 months. Walmart said to me when I tried to return it that they only work with you until 90 days and Sanyo said about the same thing excpet their number is one year. If you won oneof these tv's you are screwed to the tune of whatever you pad for it. I filed a complaint with the Better Business Bureau today ( and I urge everyone to take 30 minutes and fill out the complaint. Here is the text of mine if you want to paste it into your compliant.

Complaint Text

The product DP32746 LCD TV failed before one tenth of reasonable period for the useful service life had expired. Research indicates this model is prone to inverter failure at about one year of operation on average and that the failure is systematic in nature and is experienced by a large number of owners of the product. When the product fails it is rendered completely useless and repairs are prohibitively expensive.

Its the backlight inverter board. i just fixed my sanyo DP32746 myself in 1/2 hour. researching here, i found moniserv online store,i found the part (heres the link) they are in san francisco, and i happen to live in s.f. so i went there in person and picked up the board ,it was $179.99 + tax got home switched it out myself with a philips head screwdriver and a small nut driver .i dont have any special training or skills and it was an easy fix . sanyo were total **** about this problem i took a chance on doing the fix myself and im glad i did . good luck.

The problem is not in the panels themself, its the backlight inverter. Parts 62.70 from Sanyo.

I fall in the same boat i've had this tv a year and a half and all of a sudden the screen is black. We need to get together as a group and force a recall on these televisions. I feel I've been "taken" as a customer. If Sanyo feels any obligation to their paying customers they would take innitiative immediately. Somehow I think that won't happen. What a surprise. Thanks for a piece of garbage Sanyo, nothing like wasting hard earned money. Should've bought a Sony huh.

I would strongly suggest that people who are having problems with this tv and there appear to be many, submit a complaint to the BBB. It takes time and is a hassle but Sanyo needs to know the quality of their product stinks.

I took mine in to the Sanyo authorized repair shop and they found the screen itself was bad. Sanyo sells the new screen for $1100, almost double what I paid for it. The repair tech said they do that intentionally.

Turn tv on. green light solid display, no picture or sound

The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

My Kawasaki pvs1080 has sound but no picture, no menu, no setup.

There is a small button on top when the screen closes it turns off the display. While the movie is playing press the small button with a small pointing object and see if the display shows something on the screen for a few second and then off (you can sometime see the movie playing but very dim). then there is a problem with the switch not switching the display back to normal. Hope this helps...

No picture or sound, just blinking power light

Hi...I am sorry to say that I had this exact problem. It ended up being the upper and lower panel drives. I contacted Hitachi and even though my unit was out of warranty, they agree to pay for parts. I paid for labor myself, and it cost me $199.95.

Good luck with it...let me know how it turns out for you.
