20 Most Recent Sanyo DP42746 42 in. Plasma Television - Page 6 Questions & Answers

That television doesn't have a VGA input, but it does have an S-video in. So this is the cable that you would need to connect to get the video image on the screen. However, s-video does not carry sound. So you either run the sound from the laptop still, or use the earphone jack to bring the sound out to your surround amp, or tv.

Sorry you wont get any help from Sanyo or Wallmart. Buy another TV repair people will take your money.

The problem you have described is due to malfunctioning buffer boards. You will have to replace the 4 buffers X,Y high and low to resolve this problem. The four buffers will cost you around 150-200$. If you like to go ahead with the repair then let me know and I will help you find the replacements. Also note that in some cases it can be the panel itself though I hope thats not the case with yours.

Model number should be Printed on Back of TV.

try to contact the service center of your television unit.. so that they will fix your problem

the screen is broken inside. you need a new panel.

Hello,

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.

The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board.

I do not think it needs replacement, rather some defective capacitors are causing this issue.
Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.

The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)

You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.

What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).

You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors).
After replacing these capacitor(capacitors) most likely the normal operation will be restored.

Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.

I hope this helps.

Good luck.

IS it like the picture is being cut off? You may need to check the connections to your buffer boards and main logic boards.

Thanks,

Hi, NETFLIX is an ONLINE service, the things your t.v. would need is an INTERNET connection, or a connection for P.C. ( also may be called V.G.A or D.V.I. ) If your t.v. has an internet connection it will be called a L.A.N. or W.A.N. connection ( it'll resemble a telephone jack ) hook this up to your internet. The easiest way however is to play NETFLIX through your P.C./laptop then view through the external monitor feature of computer. So unless you have a very simplified setup it should be possible to not buy extra equipment for NETFLIX. Good luck, and I hope this helped, Prodzilla

Hello,

Your power supply board is not yet dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


Hope this help

There should be a blue vga port on the back of your tv. Connect the one on your tv to the one on your computer with a vga to vga cable.

Hi,
If you didn't get the 5v,3.3v in the output of the chopper transformer it means that it didn't gone to a complete cycle. You have a problem in the main voltage regulator circuitry.
Check the reading and let me know to assist you further.

The underlying LCD panel has broken. this can happen on many devices and is often a result of a drastic temperature change. the only option is to replace the screen ether yourself or have it done at a local tv repaire center. if the product is still under warranty it should be replaced by the provider

T-Con Board will cause this.

its your main internal power supply board

No, easy repair if you know for sure that is the only problem. It is very rare to have just an upper buffer board bad without the Y sustain board being bad also.
