Question about Sanyo Televison & Video

Open Question

This condition happens more frequently the longer the TV is powered on. At the same time the audio goes out and comes back when the picture returns after a few seconds.

I have a Sanyo DP46840 that has picture and audio. The picture has horizontal lines from top to bottom that come and go in intensity. after a about 30-45 seconds the picture goes black, sometimes black then green, then black again.

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

SOURCE: TV Picture Goes Black

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

Your model has a maximum resolution of 720p. What you might want to do is make sure that both your cable/sat box and game stations are outputting at no more than 720 resolution. It's easy to assume that all HDTVs may accept a higher signal, and while they might, some of the scene changes or handshakes may make that operation cause the symptoms you describe.

SOURCE: ACER AL1914 LCD Monitor goes black but green light stays on

The monitor is doing a self test a finding an error.
The lcd has three parts, the screen plate(windows)/the logic(vga)/the inverter(power plug). Parts that go are the backlight ccfl's, behind the plate, and parts of the inverter, ie capacitors, all three take a bit of power from the inverter. The self test check that all the lights are ok and the inverter is ok, else it switchs off, ie if 3/4 light work it will switch off(my own case), hence the on chech error then off, However sometime there are stages of on/off ie on/ but no screen display, if that is the case the following may be of help...if you put bright light at an angle close to lcd can you see a windows shadow, text icons etc, ie still logic power passing,then .... (from a.n. other) after two weeks searching I finally find doctor living stone http://www.aplusperfect.com/articles/lcd_capacitor_repair more fun with paulbtorrent
the takening the case bit off is like opening your wallet a second time after buying a new LCD, but you must! smallest two screw driver's flat headed, practice using two pennies stuck together()with your fingers after, one little () move and inch and {} again, with the case , it does not break, just need to lever open
[once open you realize they somehow put that old briefcase clip inside!] also note the bright light test to do first to see if can see a windows screen , and that capacitors are one for a number of things that a make a inverter work! there a transistors as well, given that however, to replace all the capacitors on my inverter, was 11 capacitors, cost me $11 (uk ebay) and already had the iron and solder. So only cost me me $11 to try and see but no luck , still fun and I still can see the screen for 2 sec' at a time plus I have a spare set of caps now in the event that the new one do go burst! you have to laugh really, what next , a new on/off button, as you work though the whole inverter mmmMMMMmmmMMMMmmmMMMMTim Berners-leeMMMMMmmmmMMMMMmmmmcome back all is not wellMMMMMMMMMMnnnnnnweek later land sight mmmmmMMMMMMMMMmmmmgggggggg(from
another a.n other)Generally, if the screen went out quickly, it was the inverter. If it went out over a slow period of time (flickering etc..) I would bet it is the lamp.replaceing the lamp should be pretty challenging. as that requires complete breakdown of your LCD, extraction of your dead lamp, and soldering in your new lamp... but I would like to say that I it did this after realizing it's 2 x kitchen strips inside [========] with wires that can connect back to the inverter with out any desoldering(ie kit assembly/dis) with the outter case remove (glass plate safe away) I could reconnect and see that 3/4 were working (i!i hardcard ) cause the inverter to switch off after a secound ! order bult and replace and going
to cheap and see if I can get away with fitting a 15" in my 19' as it a 1/3 of the price ! the market as drop out there, hope the inverter does not miss the length, or the screen out put.http://www.lcdparts.net/howto/troubleshooting/LaptopCCFL1.aspx OR MONITOR

Audio Issue


Hi Sharon,

I have the same exact TV and the same exact problem....except today the screen went black and I no longer get a picture from any source. I've had the TV for exactly 13 months. IF you've had your TV for less time, I'd return it.

Hi,
Replace Lamp in TV and lamp replacement procedure would be written in Instruction Manual of TV.

Always buy Sony Original Lamp for smooth picture result and avoid aftermarket/ cheap lamps.

Let me know exact model number of TV if you need more help.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.
