S-video problem on Panasonic TV
Have you tried another S-Video patch-cord?
Some cheaper ones short across pins.
What output from DVD are you using?
If composite video 'Yellow' RCA socket, a cheapo cable can also create sync problems ie signal timing, causing patterns on screen.
The S-Video is actually 2 signals - one for Chroma C and the other for Luminosity Y. With S-Video to S-Video connections, this gives better quality than composite, as each line can handle separate voltages, levels and frequency for Chroma = pixel color and luminosity = pixel intensity.
Composite has to cram all this info onto one channel, so signal quality is lower than S-video.
A hack that videophiles use is to place a 470nF ceramic capacitor across the 2 signal pins, instead of the cheaper just bridging them together.
This apparently helps to re-sync the combined signal from composite.
A tester on ohms and steady hands can test whether your cable is cheap-shorted type, or better synced type.
Across C and Y pins:
high reading or open=small sync cap
If making own cable mod:
Pins are closely spaced, so easier way is to strip and dress cable near S-Video plug, solder wires to cap accordingly, join composite to cap & Gnd as shown, insulate.

NEED A PART NO. FOR ZENER DIODE D830
It is an easy to get component, All zener diodes will have a breakdown vltage, and it will be marked on it body. Read it, and buy a new one from any electronic spare part selling shops.

Lost sound while watching TV on cable.
Likely the tuner in the set which aside from signal also processes audio---also if the set has a headphone jack take a look at that as it could cause this---small but some chance.My bet is tuner

We have a panasonic ct-36d31e that has developed a
Unfortunately magnets etc will most likely do all but improve the problem. When a T.V set is turned on it automatically degausses (demagnetises) the tube. However, if the screen does not degauss, its most likely a small electronic component in the degaussing circuit which has burnt out. This component is usually black in color, is rectangular and about the size of of the T.V. screen displayed alongside your question. Its inexpensive to replace(less than $5) and can be found at most electronic component stores.
Please let me know if I can be of any further assistance.

Hi, i need a replacement for diode number
It looks like tou can sub this with B0ZAZ0000045 MCMelectronics.com has them for less than $3.00, but there will be shipping of course. They have many other parts and supplies which you might purchase at the same time rather than pay for shipping just one small part.

Lower the price of Panasonic Color Picture Tube model A90LLD361X.
The purpose of the cost is supply and demand. I see it is not an even number, so they are giving you the charges possibly including shipping and sales tax.
Shipping those heavy buggers are also $200-$300+ to ship even down the street.
My recommendation for your question is just to upscale and go LCD....
By the time you purchase the tube, have it shipped, have it replaced.... you would have spent well over $700 anyways. Im just giving my honest suggestion. 36" LCDs are in around $700USD, you couldnt afford not to take it into consideration :)
Hope that helped! -Jordon

check for dry joints around vertical chip, also dry joints in the horizontal stage will cause this also

Panasonic CT-36D31E Television
Seems to me that the technician messed up something on the power board when he repaired the horizontal amp.. I would check for faulty solders, or components first. However, if you do not have prior experience, I would recommend getting a technician to do this, as it is very dangerous to open up a TV.
You could try a hard reset first and see if that helps: Unplug TV from power source and cables for about 2-3 hours and try again...

High Pitched Noise, No Picture, Need To unplug to make it stop
It is probably easier to take it somewhere to have it fixed as you will spend hours and still might not fix it correctly.
You need schematics for your TV.
If you really need sources for these parts, you might be able to find them from digikey, mouser or newark electronics.
