When set is cold the picture has a 'woodgrain' effect, that changes pattern as the set warms up. It would take one to five minutes to go away, now it's up to 30 to 45 minutes. Any ideas? I've tried all the video settings, and the convergence looks good.
Took to repair shop, said he took signal board out of 2nd TV and put in mine, and the picture was great. Claims components cannot be replaced on the signal board and will contact Panasonic for price of new signal board on Monday. Also said there is a place in Ohio that rebuilds Panasonic boards which may be cheaper. Any comments or sources of signal boards?Took to repair shop, said he took signal board out of 2nd TV and put in mine, and the picture was great.

On my original board, I found if I used component cooler spray on the front convergence chip, the picture would look good for a second or two then go back to the lines across the screen. I pulled the signal board and resoldered the convergence chips, and the lines across the screen are consistant now (before, they started far apart, and got closer and closer as the set warms up. When prob first started, after five minutes warmup the picture was good.) I ordered new convergence chips and changed both, The picture is slightly better, still has lines, but after 30 to 40 minutes, the set shuts off with the three blinks of the front panel red light, indicating convergence circuit problems. Should I replace the resistors, or ?? By the way, after resoldering the convergence chips the first time, the circuit cooler spray had no effect on the picture.On my original board, I found if I used component cooler spray on the front convergence chip, the picture would look good for a second or two then go back to the lines across the screen.

Possible clod solder connections ,which is why the time factor,it will only get worse as time goes on ,requires repair soon of other problem may arise .

There are plenty of reasons this could happen like the following:
PROBLEM
POSSIBLE CAUSE
Loud operating sound level
• See "Sound Information" section for explanation of normal operating sounds
Freezer too warm. Compressor not operating
• Freezer temperature set too warm
• Defective compressor
• Defective overload or relay
Refrigerator too cold
• Refrigerator temperature set too cold
• Chefs Pantry control set too cold or misaligned allowing freezer air to escape into refrigerator section
• Freezer temperature set too cold
• Restricted condenser air
• Refrigerant shortage or restriction
• Refrigerant overcharge
Freezer too warm. Compressor cuts off on overload
• Heavy usage
• High ambient
• Restricted condenser air
• Defective condenser fan motor
• Loose or missing condenser fan blade
• Improper voltage
• Defective relay or overload
• Compressor motor winding
• Non-condensibles in system
• Refrigerant overcharge
Freezer too warm. Compressor operating
• Freezer temperature set too warm
• Restricted condenser air
• Defective condenser fan motor
• Opened door
• Heavy usage
• Defective freezer fan motor
• Opened defrost thermostat
• Opened defrost heater
• Loose or missing freezer or condenser fan blade
• Heavily frosted evaporator
• Refrigerant shortage or restriction
• Inefficient compressor
Refrigerator too warm
• Refrigerator temperature set too warm
• Freezer temperature set too warm
• Return air or air supply duct blocked
• Chefs Pantry control set too warm or air supply tube blocked
• Heavy usage
• High ambient
Problem
Possible Cause
Freezer too cold
• Freezer temperature set too cold
Long off cyde
• Low ambient
• Freezer temperature set too warm
Short off cycle
• Heavy usage
• High ambient
• Freezer temperature set too cold
• Light constantly on
• Poor door gasket seal
Long or continuous run cyde
• Heavy usage
• High ambient
• Inadequate condenser air flow
• Freezer temperature set too cold
• Loss or restricted refrigerant
Short run cycle
• Light usage
• Low ambient
• Freezer temperature set too warm
Exterior cabinet condensation
• High humidity. Design accepts beads of water on cabinet exterior after 4 hours with 0° to 2°F (-18° to -17°C) freezer food temperature and 38° to 40°F (3° to 4°C) refrigerator food temperature in 84% R.H. conditions. See "Typical Sweat Pattern" section under above conditions.
• Freezer temperature set too cold
• Poor door gasket seal
• Insulation void
I would check the water tempeture knob with a multimeter, u did check the water outlet hoses to see u are getting hot and cold water from them? Also if ur water inlet valve is bad it may only allow cold water or only hot water?
Need year/make/model/mileage of vehicle to provide a more specific set of troubleshooting steps.
When was the last tune up? Hard starts when cold are usually caused by fouled spark plugs, worn plug wires, or weak ignition coils. Fuel systems are not as effected by temperature changes as the ignition components.
yes it needs repair. by saying "This doesnt show up before I take a picture" this means their is no problem with the ccd or image taking section. the problem is occouring while saving the photo.you camera needs repair.
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.
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 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.
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.
Reference
You may find another Moire effect displayed on the LCD of the camera. As this is caused by the aligned pixels on the LCD, this effect does not necessarily appear in pictures you have taken.
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.

When the pixels and the 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 cross-stripes and black cross-stripes 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.
