    I get tiny red dots in the screen, especially during the night scenes when it's dark, or when I turn the TV on, and the screen is still blank, you'll notice those same red dots right before the program comes on. What's causing those dots to appear?

Got it new at Walmart in 2006? Never had any problems with it, and always had a surge protector. I know the kids have abused it though. Anyway, yesterday they had a pink, washed screen, turned it off/on...


No.The tv video board have dead components,that the board where it is connected to the CRT-(tv picture tube).Troubleshooting that video board and changes parts should fix ur tv problems.Hope ur tv problems,it is not the video board main big IC colors processor inverter.This big IC is a pain to change and probally not in the market anymore.Troubleshoot test all the capacitors around that big IC colors processor inverter alot of times just those few capacitors are dead only.

The convergenceboard is on the fritz. Located on the small signal module, there are two convergence ICs that will need replaced as well as several resistors. See a tech to repair this! Please do not adjust the screen colors or turn any potentiometers. It does not sound like you are in big trouble yet! Thanks for asking!

Color


see if there is a "default" option, if not set everything back to the middle, if the colors are still off you sure its not the convergence?
most big screens allow you to change "color temperature" it's like a default adjustment for 3 different brightness levels.... ie...COOL, WARM picture will show obvious changes in brightness

Need to find out how to adjust color


im curious why you think you need to ajust the color do you have red screen? or missaligned colors?
If your B&W images look okay (bright and dark areas), either films, ads,
or turing the color off, you shouldn't tinker with grayscale
adjustments. You'll really mess up your set. Haven't seen many
complaints about 'red push' with Pioneers, but that may be the problem.
A further check would be the decoder test on the Avia disc. Also visit
http://www.hometheaterspot.com/ and search the Pioneer section for
similar complaints.

Your convergence amps are bad. Replacement is necessary and I would recommend contacting a servicer in your area. You can find an authorized JVC serivcer at this link http://maps.jvc.com/cAscList/

The Picture is filled with rainbow colors


Hello Big Sav,

It sounds like you have a Convergence Correction IC problem. This problem happens quite often and is fixed by replacing the ICs and the biasing resistors. There are many articles on the Internet about how to do this yourself. Here is one:

I should mention that, If you do not have a background in electronics you could do damage to your TV by performing this procedure. I you feel that you can not perform this procedure properly have a qualified technician perform it or have the board serviced at a TV repair shop that specializes in board repair.

I hope this helps,
Thank you,

Red drained out of picture


The red transister on the CRT socket could be at fault. there is 3 transisters on the socket check for the voltages on all 3. If the red is high unplug the socket and see if it normal if not the transister or circuit feeding has a short. If low the same case seneral applies and a resistor feeding the transister is defective or the transister itself is at fault
