January 15, 2007. I am back again with a new problem with my JVC AV-32F476 32 inch TV, which I purchased less than a month ago today. Again, the problem seems to have developed on its own and stayed. I wondered at first if it had anything to do with my antenna reception (no cable) but was told that it is probably an internal TV problem. Here goes:
The people in the picture seem to be all legs most of the time, and quite tall. As well, they could be legs and chest with a small head which seems screwed on, like a robot's. Although sometimes, and this is rather rare, in the same program you could find a normally proportioned person, but the next one is not, and I don't think it has anything to do with the angle of photography. As well, everybody's face seems a bit longer. Changing the Aspect helps a bit, but I like to watch it on full screen. Also, I changed the settings from Theatre to Standard. That seemed to help also, but the problem persists.
I remember in my black and white TV many years ago, one could adjust this with a button at the back of the TV, but now, there does not seem to be any such thing.
I wonder, is this a defective model? Or is it just a defective item?
Thank you for your help.

I believe you are absolutely right and thank you. Not only does my TV have a warranty, but the l6th was my last day to return or exchange it,no questions asked. However, for reasons of health, I did not do that, especially since I did not know whether I would be exchanging it for another to go through the same thing again. Obviously quality control is not the best.
I appreciate your solution, but tell me, are there set standards for it? Obviously again, the error margin must be big since it came this way.
Also, the problem seems to have improved somewhat, (at least the disproportion is not as offensive, though people look heavier), when I adjusted the "Detail" setting to two degrees lower, while before I had it on two degrees higher.
Thanks again.

Oh yes. Shipment and handling! I once saw soemone bang a computer box on the sidewalk. Never mind that. Last year I saw my brother's 3000 dollar Sony being "dropped" on the ground, and when it arrived inside the house it was upside down even though it was stated clearly to "make sure to Keep This Side Up".
It is unfortunate that quality inspection is done randomly, thus putting the burden on the consumer who should be getting a cleared item. If they did that they could be more stringent in their delivery standards. I guess what it boils down to in the end is savings, plus they are banking on consumers not being too picky sometimes, or choosing to keep the less than perfect item despite its defects rather than go through the hassle of delivery, waiting and not knowing what they will get etc. However ... such is life today I guess.
Now how technical is THAT! :-)

Re: Distorted Picture Proportions
Well i beleive ur tv still have a warranty since it is purchased less than a month ago according to you. i suggest that u use it and have it check with their technician. it seems that there is an internal problem with your tv, particularly the vertical circuits. did u try to hook up another tv?
this symptom is caused by a poor vertical linearity wherein the image is compressed or stretched at the top or bottom of the raster
yes for sure there is a standard for this. unfortunately quality inspection is being done randomly. consider also the shipment and handling of the unit. remember this is a very fragile unit. it has a glass which is the picture tube. a mishandling will lead into a seriuos problem.yes for sure there is a standard for this. unfortunately quality inspection is being done randomly. consider also the shipment and handling of the unit. remember this is a very fragile unit. it has a glass which is the picture tube. a mishandling will lead into a seriuos problem.

Ur tv are developing a problems call convergence,it dying.The convergence board the 2 STK convergence ICS,and some or all it resistors are dying.These parts are must be changed to solved the convergence problems.The shop will cost u $300-350 for the parts and labors.
There are probably two capacitors that are bad in the vertical circuit. Not too hard to replace if you have any experience at all. Find the vertical output IC ( usually IC451 or similar ) and simply change the closest electrolytic capacitors. A professional can do this easily. Could cost up to $150.
Worth taking it in since it is hard to find a new TV for less than $300. I have a 32 inch JVC iart that for about 2 years would turn itself off and the timer light would blink. Only thing that worked would be to disconnect and turn back on. Eventually, the tv "popped" I could smell something that burned out and within 3 weeks tv went "dead" Took it to a tv repair place and replaced power unit for $150. I had similar problem with a 19 inch Philips and that tv has been going strong for 4 years since repair.
From what you describe, a solder joint has probably cracked loose in a power supply or deflection circuit, which is quite common. Since you do sometimes see a good picture, all of your major components are fine. Repairing cracked solder joints is a very easy procedure and definately worth fixing on a 32 inch TV. The first 2 digits of the model number indicate the size of the TV.
sound like you have 1 or a couple of leaky/bad capacitors in the tv's vertical circuit, typically, there sould be 5 to 10 caps. in all, but you just need 1 bad one to cause your problem.
good luck.
One thing you should not do with electronic devices which have a start up proceedure is to turn the power off, and then on again without a wait of about five minutes.
Some equipment manuals warn you about this, and specify a longer period.
The start-up has to have time to reset.
It will be more likely to reset if you do not leave it on standby,
and even unplug it.
In your TVs case you need to describe the distorted picture as it may give a clue to a fault, or incorrect start-up.
The horizontal line indicates the frame timebase had stopped working.
No picture could be a fuse blown inside the set, or a timed cutout which may reset after a time.
Try after several hours to see if it comes on.
If it is just the frame timebase (vertical) it is worth repairing.
