Sanyo TV goes streaky plaid?

Can't find a pattern to it, but our TV constantly get streaky plaid and stays that way for a long period of time? We've tried turning it off, switching inputs, etc. it will go plaid in the middle of a show or movie or sometimes as soon as we turn it on. Sometimes, the picture splits in the middle and is inverted? Guess we're going to buy a new TV soon

It sounds like you have a power supply problem, this powers the inverter! Where you just replaced the inverter, we could assume it is good! Look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain). The power supply can fail on some output and be good on others. Was the back light inverter new? If all else fails, see if you can return the back light inverter and get another! I hope this is helpful!!

SOURCE: My new Sanyo HDTV LCD won't come on, although the on light is on.

If your Tv is in warranty or you have a cover plan, you need to return the Tv for repair or replacement.Your Tv sounds like it has a power supply fault.

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.

We just purchased a 55 inch Westinghouse tv and I've notice with a full white screen what looks to be a plaid pattern. It's very slight with squares that are approximately 4 inches.


This is tiling which should disappear when you select a better resolution on display via remote.you should be at 720p so anything below that setting will pixelate or tile.

Sanyo tv and i am using 2 inputs and they seem to 'bleed' over. one is a computer input(hdmi) and the other is a cable input(v\pb\pr). in additon to the 'bleed' it has resently starte


No sure what you mean by "bleeding over" It would probably have to be seen in a picture to really know what it is. If you hear zapping that's going to be a high voltage problem inside of the tv itself. It could be the flyback going bad or maybe a grounding problem.

I have an old Sanyo 28" CRT widescreen TV. It works fine in PAL-50hz but when in PAL-60hz the colour constantly changes from colour to black & white and back again every few seconds.


I think the message is in your message - "old Sanyo CRT" (or old anything CRT, no discrimination towards Sanyo intended)
It's not LCD screen snobbery on my part either. I've a Panasonic 28" CRT I got new for £49 in a clearance only two years ago. OK it was a 2007 model but unused.
That will see me along nicely to avoid an LCD TV, I'll go for projection or LED screen when the Pana. dies.
However, this aint' getting us further along with yours.
Why do you need it to be in 60hz mode?
Is this something to do with viewing a USA NTSC system linked device?

Check if it has a scrambled image on all sources ie - DVD- VCR - cable/satellite box. Since the PIP is normal it sounds like the signal source is bad.

Green Plaid lines on Samsung HLR5067wax/xaa-


These are the Tests that should be run to determine which board is bad.You should call a good TV Tech if you are not familiar with this TV.
- The DDP1011 on the DMD board has a feature to display internal test patterns.
- DNle, which is an end port in the digital board, has a feature to display internal test patterns.
- The analog board sends signals to ADV7402 on the digital board.
- The analog board is the first output and the digital board is the second one, followed by DMD, which is the final one.
■ Diagnosis By Module
1. Access Service Mode
(In Standby mode, press "Mute", "1", "8", "2" and "Power" to turn the screen on and enter service mode)
2. Check if there is an error in the DMD board
DDP1011 → TEST PATTERN → Press the right arrow key:
Options of FULL WHITE, BLACK, RED, GREEN and BLUE PATTERN are displayed on the screen.
If "Pattern" does not appear, this is a DMD board error.
3. Check if there is an error in the digital board before the DMD.
When the DMD board has been determined to be error free based on the test patterns:
FACTORY MODE → DNIe → TEST PATTERN normal display: no error in the digital board.
If "Pattern" does not appear, it may be from a DMD board or ATI error or there is an analog board malfunction.
4. Check if there is an error in the analog board.
Check for a power signal from the analog to the digital boards

Picture ripples


The following describes the symptoms, cause and prevention of the Moire effect. Symptoms of the Moire effect When you are shooting a subject that has a fine regular pattern such as stripes or plaids, a ripple that does not exist on the subject sometimes appears in the image. An example of this can be seen in the pictures below. The photo on the left shows the fine plaids pattern on the shirt. The photo on the right is a distance shot of the same shirt. In this photo, you can see a ripple that is not visible in the photo on the left. This effect is called the Moire effect. Why does the Moire effect occur? Digital cameras and camcorders are equipped with imaging devices such as CCD sensors and CMOS sensors that have pixels that are finely aligned horizontally and vertically that convert light into electronic signals. When the pixels and the fine pattern on the subject overlap slightly misaligned, an interference pattern occurs and a ripple that does not exist on the actual subject may appear. This is the Moire effect. Look at the image above. This image shows red stripes and black plaids overlapped slightly misaligned. When you look at the entire image, you find a ripple that differs from either of the patterns. This is the same principle that causes the Moire effect. Preventing the Moire effect You can reduce this effect by changing the distance, zoom setting or the angle of the image. If you are using a camera with manual focusing, the Moire effect can be reduced by simply changing the focus slightly.
