Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: KDF E60A20 screen goes blank loses sound for 10 60 seconds

I've had this same problem ongoing for a couple weeks. Finally, tonight it would shut off every 20-30 seconds, stay off for another 20-30 seconds then come back on. It turned out to be my bulb. I blew the TV out with compressed air, removed the bulb and disassembled it. Taking the bulb out of the plastic cage I then remove one of the metal screens at the top of the bulb, it just has little clips holding it in. I took a bottle of rubbing alcohol, some Q-tips and proceeded to clean the inside of the bulb through the screen hole. After cleaning the inside I put the screen back in, cleaned the outside of the bulb with a rag and alcohol, then reassembled everything. The TV is much brighter, I had to turn down the brightness setting and has been running the last few hours without an issue. You can avoid all this by buying a new bulb but I don't have the money right now to replace it and I'm cheap so I'll milk this bulb for everything it has. Heat kills bulbs so if you clean the screens and blow out the TV once every couple months you'll get a lot of life out of it..... I'm almost to 4 years on my original bulb and my TV is on constantly!! Good luck to all!!

You need a lamp. This is a common symptom. I hope this helps. I have a tutorial on the function and failure of lamps, check it out if you like. It explains why your TV is doing this. I hope this was helpful.

When I turn the power on my Sanyo DP32648 the picture goes on for a few seconds then the screen turns black but there's still sound.What's wrong with it.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electro-medical.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board....

Hi,
I should say, it's either the inverter cable needs to be re-seated/replaced or the LCD screen needs replacement.

TV powers on but there is no picture


0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.

Thanks!

My Sanyo DP32648 was plugged into a surge suppressor and during a lightning storm the TV turned off. The DVD player, stereo and the clock are all working fine, and were still plugged into the same surge...


If you look at the power supply board as shown in the picture: http://assets.shopjimmy.com/media/catalog/product/cache/1/image/5e06319eda06f020e43594a9c230972d/s/j/sjdps153ap1a.jpg

There is a main fuse on the top left of the board covered by black shrink tubing, SLO-BLO 4A 250V. Check it out to see if it is blown.

I have a Sanyo DP32648 that keeps losing only one channel in the program. When the TV is turned off, that channel disappears from the program. I have to manually reboot the entire list. How can I solve...


It sounds like there is some electrical noise interference that would not be "fixable". If though, we reconfigure the way that they are connected together, we may be able to avoid the noise.

Instead of allowing the antenna signal to "pass through" the 625 we will skip it.

After following the directions, switching between satellite and antenna will be done by selecting on the SANYO "Input 1" for satellite, and selecting "Ant" for antenna. K?

Try this:

From the 625 Tuner 1- using RCA cables (a.k.a. composite cables, or red, white, yellow cable), connect to "Input 1" on the Sanyo TV. To see composite cables go to http://www.wowvision.tv/settingsandconnections.htm

Next, remove the coaxial cable between the Sat box and TV. (Sanyo "Ant. In" port and 625 "Out to TV" port) Set that cable aside.

Now, remove the incoming antenna cable from the 625 "Ant. In" port, and connect it to the Sanyo's "Antenna In" port.

Finally, scan for channels and check for the presence of CBS.

Once verified, test the TV by turning off and on.

Turn on the satellite receiver and switch Sanyo to "Input 1" to verify sat picture.

I believe this solution will satisfy your needs. Please let me know if it doesn't work, and I will need to talk to you about signal strengths, again.

God bless,
Highdefjeff

Tv worked well last night...turned on this am.. sound but no picture


beachbabyfou, Use Sanyo warranty first, if covered. If not , then you or a electronics technician will need to troubleshoot and repair the unit's "switch-mode-power-supply" board. Partial power supply failure and unit can't "light-up" the cold cathode fluorescent lamps anymore. Is unit CCFL or plasma? If CCFL then possible same type problem as computer ccfl back-lit lcd monitors. Read some of the stuff in my fixya profile (older, higher pages) for more info. How old is unit? What is DOM? post back info you find. Yes, it could be failed capacitors on printed circuit board. Only rate this response if it helps you. 12fixlouie

Picture & sound go on & off every sec, red light blinks 5 times


helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.
