Call Sanyo. The 800 number is on your remote. Insist on talking to a supervisor and you may get somewhere. I had to do this and Sanyo called today to tell me to take my tv to the shop. They are paying for parts and I have to pay labor to get it fixed. Repair shop said $35.00 to look at the set and if it's just to boards that need to be replaced, it wouldn't be too expensive. We'll see.

Sanyo told me they haven't gotten many complaints on this tv, DP42746, 42" Plasma. You guys have to call them and complain.

We're is the reset button on Sanyo model number DP42746


There is a reason for everything.

In this case you might need service of your power supply or a replacement buffer boards or , sometimes, a simple dismounting, cleaning and mounting of the TV.

But most of the time it would be around the Y-sustain and buffer boards.

Sanyo model dp42746 powers on but black screen and no audio


Clicking noise is usually produced by a shorted load or overloaded SMPS (power supply), black screen as you had mentioned may contribute to a short circuited load.Check voltages (secondary) might be pulsing from high to low that sync the clicking sound.Checking load resistance through filter capacitor will help a lot then try isolating circuit branches to localize the shorted or leaky parts.Try isolating(one at a time) the power supply's loads may help a lot.

Our sanyo dp42746 went black made a pop sound and would not turn back on no power light or nothing


Most likely a power supply board went bad. the pop sound is bad capacitor on the board. Most bad capacitors will look like this: 18976c2.jpg
The other picture below shows a normal capacitor in the middle, but two bad capacitors on the sides of it. One with the dome top and one leaking. 5d53c3a.jpg

You can try repairing the board by replacing the capacitors or replace the whole power supply board. Most replacement boards can be found at a good price at Shopjimmy.com or Ebay.

Problem is on the Y sustain pwb, to the left of the power supply. To varify, unplug the connector from the power supply going to the y sus. The set should then start up, and you'll have audio. Call sanyo at 1- 800-877-5036 for parts. Or www.shopjimmy.com for used circuits at a discount price.
