Sony big screen television part

I am looking for a part for my Sony t.v. It is called a "green picture tube," (probably not the technical name), and the part number is 873365205. It is from model number KP-51HW40. Could anybody help me find this? It is not manufactured anymore, but I'm sure someone has a used one some where out there.

Magnavox big screen has dull picture and colors are not clear. Cloudy picture and has a green film of color over screen. this ia a 64inch big screen. What can

This is especially common with Phillips/Magnavox - A foggy image usually suggests that the coolant in the picture tube(s) (1or all 3) has become discolored and needs to be replaced. The only way to check this is to look directly into the crt faces (disassembly required) to see the condition of the fluid (coolant).
It's a relatively big job that shops charge between $300-400 - Get an estimate. See link for Kit

Sound but no picture is it the picture tube or just another problem

most likely will not be the tubes mate, if the tubes go then you just get a big mix of red green and blue colours in the screen - sound but no picture is more likely to be the starter unit on the flat screen.
flat screens have a starter unit - mine went on a samsung but under warrenty

Tv keeps blinking to black screen and back to normal. (sony trinitron)

Probably the picture tube getting weak, those sets have a circuit called IK Blanking that samples the three colors of the picture tube and if they are not equal the circuit blanks the picture. Another clue is if occurs less frequently the longer the set is on because the picture tube can get a little stronger as it warms up.

My Sony FD Trinitron Wega has no red color on the screen. All the usual adjustments don't help. No other TV in the house is doing this. Is the picture tube dying? Is it worth fixing?

Its technical document of any product for techs only and usually does not come with product. You can download copy from HERE for small fee. It calls Service Manual.
Below is an image of that service manual.

Picture is going fuzzy and blinking red light...

This is the classic symptom of a CRT (picture tube)that is starting do get weak. The picture takes longer and longer to come on, it appears greenish and blurry, and it blinks on and off in different scenes, and when it is off the timer LED blinks 5 times. Sony has a circuit called "IK Blanking" which monitors and adjusts the colors in the picture tube, and shuts the picture off when the tube is getting too weak. The good news is that the Sony tubes always respond beautifully to a CRT rejuvination (recharge), and the picture returns to perfect. Since the set is 36 inches and VERY heavy, it should be serviced in-house and an appropriate charge for a service call for your set should be around $150.

A "Gray Scale" adjustment may solve you problem. If one of the picture tubes is set too high it will cause these RETRACE lines. Then too a weak picture tube might cause this. If the horizontal lines are one color: red, green,or blue then whichever color that is shown would tell you which tube is set too high. Your set has 3 screen controls that control the brightness of each tube. One may need to be turned down a little. Stargazer

Problem in Screen display

Hi, J ! You didn't say how old you set is, but to me it sounds like you may have a warped shadow mask in you picture tube. A shadow mask could be compared to a piece of screen wire. It's function is to make the electron "beams" from the three electron guns strike the proper phosphor dot to produce the proper color- red-green-or blue. If this is the case the picture tube would requie replacement. Stargazer

Sony kv-32hv600 picture problems

Problem 1. Color patches at lower corners. These are caused by magnetic sources close to the TV. Do you have any Speakers close to the sides of the TV? Are they Magnetically sheilded? No? Move them away from the TV. Problem should then resolve itself in a couple of days. Problem2. Screen Slumping. Most likely a problem with the Pin cushion correction ckts. Get a good technician to have look. cost should not be much. Under 100$ plus Technician fees.

Solid green screen

Is the green really bright with small white lines in the screen?? If it is its probably a shorted picture tube. That is if you still have sound. If you have no sound its probably a power supply problem in the sweep section of the set. This is not a repair for a consumer to do as its a solid state set and there are no user serviceable parts inside these sets. Get a service person to assit you with this repair. Good Luck
