Question about Sanyo DP42849 42 in. HDTV

1 Answer

Sanyo dp42848 turns on, picture comes on then goes off after a few seconds, sound still works. Ok, here's the weird thing, I used my old tv for a month, after 2 weeks of not being plugged in I tried turning on the sanyo and it still didn't work. Now it has been probably a month and yesterday it started working hasn't even been 24 hours and the screen went out while watching tv and turning it on and off the picture is back to coming on then going off. What could be wrong that it started working after a month and now stopped working once again?

Sounds like a loose connection to the display panel. Did you physicaly move it from the time it didnt work to the time it started working..

    i'm very electronically challenged...what connection could be loose? We physically moved the tv when it wasn't working to bring my old tv in but after moving it back into the room it was working and I haven't touched anything on the tv since, it just stopped working out of nowhere again..people keep talking about bad backlights and inverters and things I have no idea about but the fact it started working again means what?

Picture for only a few seconds then goes dark

Hold a flashlight to the screen after it goes blank, if you can still see anything on the screen, then it is time to replace the inverter boards (there are 2 of them, VIT71043.50 and VIT71043.51).

I had the same thing happen to a DP42848 I'm repairing but I could smell ozone on the left side so I didn't replace anything. I just disassembled the screen and found four flouresent tubes not working! I exchanged them to be sure it was the tubes and it was.New screen is out of the question. I am trying to find a broken used LCD screen somewhere and rob the tubes from it as they just snap in and that might not happen so goodbye tv!

It only tells us that the inverter cable needs to be reseated or replaced. It's not an expensive repair so fortunately you can consult any local certified technician and have them work on this.

I have a sanyo model #dp42848 and when i turn it on the picture comes on for a few seconds then you hear a noise the the picture goes out. The sounds still works. What could this be and how much will it...

Hi art_davis,
Power on the unit in the dark room then shine with the flashlight directly in the screen, you will barely see the images. This is because your backlight is not functioning. The following reason was the caused.
1. Power supply - missing B+(supply voltage) coming from this board feeding the inverter board. This is caused by faulty transistor, dried/leaky electrolytic capacitor, open fusible resistor.
2. Inverter board - even the B+ is good from the power supply, if the fuse, driver transistor, driver transformer is faulty no output to the backlight resulting to black picture.
3. Busted backlight - even inverter board is good but if this is busted resulting to black picture also.

Check the parts here.
Diagnosing the fault is technical and if you don't have necessary tools and test instrument and can't fix it yourself, I would advice you to look for an experienced technician to isolate the problem.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
