Question about Sanyo Televison & Video

2 Answers

I have a 42 inch Sanyo LCD. Green power light comes on, nothing is displayed, no sound, no light coming from back of tv. About every 10 seconds green light flashes on front.

Capacitors look fine on both the boards, no leaking or cracks.I was watching TV one day and went to switch to a video game on the hdmi port, it had issues picking up hd signals so sometimes I had to power on off until the signal was received. However this time nothing happened besides the power light flashing once about every 10 seconds.Any help is appreciated.

    Can you direct me towards some information on testing them?

    From what I'm finding I need to buy a special tool to check the capacitors. Or can I use a digital multi-meter?

  • Brad Brown Mar 19, 2014

    You do need to get a special meter, it is called an ESR meter. These can be expensive and you might not use it much. One the models that I like is the "Blue ESR meter" google that and see what you think, then if you do want to find bad caps, you need to remove the board, test all the caps, desolder the ones that are bad and replace them.

Fault at its main digital 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. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hello my Sanyo dp42849 42 inch has no picture and no sound. when i turn on the tv a green light in the bottom right hand corner comes on and occasionally flashes off and then back on.


First, you need to know the sub-model of your TV.

It is called "chassis" and is shown on the back of the TV on the label where the model number is shown.

For example it can be "P42849-00" or "P42849-01".

Then search at www.coppelltvrepair.com/search or just go to www.coppelltvrepair.com and enter the link for SANYO DP SERIES to search for that.

Here's an example of a repair service (note it may NOT be the one for your exact model though!):
