Question about Televison & Video

Www sanyoctv com

Model DP32640 -- no picture and sound comes & goes -- had an earlier problem in that picture would not come on or wasn't right on the screen and sound off |& on but could correct by turning unit off & on 2 or 3 times and then it would work okay. However this doesn't seem to correct it -- is there a way of rebooting the TV to correct this or is it a throw away?

SOURCE: TV Black-out

The horizontal sweep circuits are at fault. There is an intermittent loose connection. It is likely a loose solder joint and it may be possible to spot if you have a magnifying glass and an eagle eye. The heavy lead that comes away from the side of the picture tube (CRT) will lead you to the Flyback Transformer area. Stay away from that wire - it'll knock the soup out of you if you don't know what it does - even with the power off. Don't try to re-solder everything in sight. You could do more harm than good. Examine the circuit board - you may be able to wiggle the cold solder joint and see it move where it shouldn't be moving. Good luck TVGUY

SOURCE: No picture when TV is turned on, sound is OK

Lets try something ,turn the set on and put you forearm in the face of the picture tube if your hair stand to static it means you have high voltage and your set is missing possible the screen or filaments volts,if the hair in your arm does not stand your set is missing the high voltage and the problem is related to the flyback but it does not mean is bad ,it could have a loose conection in one of the legs or in the near area,next time it happens tap on the side of the set to see if it reacts if it does you know you have a loose conection.If you are familiar with tv service this will be a good place to start but if you are not too familiar be safe and call for assistance from a servicer.Let Us know if you need more information and how it goes.

SOURCE: Picture and sound go away after 2 minutes

Protection circuit fault kicks in. No vertical Deflection (V STOP),B+ over voltage protection (OVP), This is about a $150 -$200 to fix.

SOURCE: Sony kv35s66: No picture, just sound and red blinking

The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.

Sayno 32in lcd DP32640 is making popping sounds then either goes to a screen that has no picture but lines or the picture is too big. then HDMI will come up like it is restarting itself. Help


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

8 out of 10 times this would be because the power supply failed due to a power surge.

1 out of 10 times it would be because the main board got a surge through, say, antenna input and got fried.

1 out of 10 times this would be totally unrelated failure to the lightning that could have happened for whatever other random reason, but would still be one of the two failures mentioned above, just for a differnet reason.

The power supply board for DP32640 should be PWB.POWER.N8LF and goes for about $29 on eBay right now.

I'd give it a try if I were you.

Before you do that you may want to test your own power board.

Search at http://blog.coppelltvrepair.com for power board testing - it won't have yours, but it will have others and the principle is going to be pretty much the same as with most 32'' and even 40'' LCD TVs.

Hope this helps!

The power light merely indicates power is being applied to the TV. You may have had a failure of a fuse or the internal power supply
