Sanyo HT32744 Picture mostly green and blue

This TV is only 2yrs old but it is already giving us trouble. Suddenly the picture will turn a ghastly shade of bile green, (faces looking like the Incredible Hulk) with an equally disturbing shade of blue for contrast. This event happens without warning, sometimes it looks like that when the set is turned on, sometimes we can watch it with a normal picture for hours and then it will suddenly change, there is no pattern to it. It affects the video too. Sanyo says a part needs replacing but when it went into the shop they only cleaned the contacts. It came back and worked perfectly for a month, now it has gone again. Sanyo is still offering to replace the part free of charge even though it is no longer under guarantee, but, (you guessed it) the electronics repair shop has very conveniently stopped servicing Sanyo. Any advice would be very welcome.

Re: Sanyo HT32744 Picture mostly green and blue

On mine I took the rear cabinet off, unseated the card mounted on the picture tube, applied a little dielectric grease on the connector on the card and reseated the card, removed, re-greased and reattached the card. I have had no problem with either my or mom's which I did the same to since! This is an easy fix that anyone can do. The hardest part is moving the TV and reassembling the rear cabinet. Do not pull the cabinet back out more than you have to, to ease the reassembly of it.

Re: Sanyo HT32744 Picture mostly green and blue

I usually find that the solder joints on the CRT board have cracked and cause this symptom. What you are describing indicates that the red gun is intermitten, and the solder joints on the CRT socket itself (red cathode) or the red output transistor have probably cracked loose.

Green Screen on an HDTV

I do not believe there is any easy fix to this. The problem may be either in the picture tube or the related circuitry. The worst case scenario is the tube itself is failing. However, it could be as simple as a defective connection on the pc board at the tube for example. You may want to get a technician to check it out and get an estimate before you buy a new set. Good luck

Lower the contrast first.

If colors not in balance, reduce saturation until "normal" to your eye with whichever color (or color pair) out of balance.

Suddenly no picture

It's doubtful your dog caused the problem; this model has seemed less reliable than most Sanyo products, there are many threads to be found detailing a number of different failures.

The problem is most likely related to the power supply but its behavior could be caused by protective circuits and a failure in the high voltage section.

You may have trouble having the set repaired for less than the cost of replacement. Parts specific to models over 4-5 years of age may be tough to find and you may be without TV for weeks if you choose to repair it.

Black pic on tv turns green

normally this means the high voltage preamp green control transistor on the neck of the tube circuit board is loose solder connection from heat or is going bad.

Picture is fine, but the sound won't work

Are the yellow, red & white cables RCA phono plugs?

Yellow = Video
Red = Right Audio
White = Left Audio (mono)

The red, blue & green cables are for picture only and don't include sound. Have you tried using the red, blue & green for the picture and using the other cable, red & white for just the sound? Don't use the yellow.

Good luck!
