Picture is intense white (not snowy)& picture vibrates once in awhile & then stops. All external components are disconnected from the set such as DVD/VCR so TV runs by itself. Anntena check okay, DVD input image ALSO produces WHITE picture. Messed with adjustments resulted w/no change. Mysteriously it worked last night. Today NO. What is the problem/issue?? (Tom)

Re: GE 31GT660 picture is intensly WHITE
The GE (actually RCA) 31GT660 uses the CTC187 series chassis. This chassis is notorious for bad solder joints on the shields around the tuner and microprocessor. When the solder joints on the shields crack, the microprocessor and EPROM lose their ground and the EPROM's data becomes corrupt. The solder joints on the shields will all have to be resoldered and the EPROM reprogrammed or replaced by a qualified tech familiar with the 187 series chassis.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture. If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.
have you connected up correctly, have you selected correct EXTERNAL inputs, you do NOT "tune" a Channel to see picture, you choose external AV input on set. Must connect color to color. 3 for Composite Video AV.Yellow, Video, Red & White Audio. and 5 cables for Component 3 for Video , & 2 for Audio Blue, Green, Red, Also Red & White, Audio.
This is your Picture tubes getting very weak.( low in emission ) You have three in there and I guarantee they are no longer available so I would start thinking about investing in a new set, but use that one until you can't stand it anymore.
yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit.
When shooting with flash in a location where there are many suspended particles, such as in a dusty area or on a snowy day, the image may contain white circles as shown in the picture below.
Why does this happen?
If the flash fires when a suspended particle floats right in front of the lens, the reflection of the flash from the particle appears more intensely than that of the subject, as the particle is much closer to the lens than the subject.
Therefore, the reflection of the flash turns out in the image and causes an effect such as that shown in the sample image above.
The closer the lens and strobe are located, allowing suspended particles to be exposed to more light, the more frequently this effect can occur.
How can I avoid this effect?
Ideally, it is best to shoot in locations where there are very few suspended particles. If not, you can use following method to prevent this effect.
a) Avoid using flash by lighting the area as much as possible.
b) If your camera has a zoom function, shoot at a wide angle.
c) If you can attach an external flash, use the external flash to distance the flash from the lens.
