Why can I hear 50 rear projection tv no picture yes on sound?

The projector and the audio system for the TV are completely separate. There are many reasons your projector may not be working, however it's failure will not always effect the audio which runs through it's own circuits and amplifier to the speakers. Think of this as if you had your computer's VGA out plugged into a projector and the mini audio output plugged into amplified speakers. One will not effect the other unless your problem is a loss of power.

I cant get it to work on full screen

I am having this same problem as this one above (62HM95). The issue I'm having is that it will also not work full screen. I selected the 'Split' option on the remote and the picture on the left is fine... absolutely clean and perfect, with audio. The picture on the right is completely distorted in very strange colors (mostly constant variations of purple), with audio as well. You should note, that the same video information was feed into different imputes to select for the split. In other words, I feed the cable stream into the TV using the component video (Y B R) as well as the coaxial cable and selected both options for the purposes of displaying the same information side-by-side. On screen I selected video option four (4 for color stream HD) and option (0 for cable/antenna). If I highlight either side and select one of them (4 or 0) the screen goes full screen and I see nothing but one solid color of purple. I've researched the purple and they call it 'Electric Purple'. That is all I see... just the solid purple, with the audio. What I have also noticed is that, If toggle between imputes while in the full screen option and come back to either option (4 or 0) the image plays/appears OK for about 2 seconds then goes back to solid purple. I just can't understand why this is happening especially when the on-screen menu displays perfectly fine. I cannot enjoy this TV by only watching half of it in split mode. Besides the multiple replacement bulbs I've had to buy I've completely had it with this TV

Picture just went black. menu, inputs - nothing

Is the standby light blinking? If so how many times? It could help narrow down where the problem is. At this point it could be anywhere. Most likely in the high voltage section. Get me more info and I will try to help.

Samsung HCN4727W Rear Projection TV, green screen, audio works

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai2_bing.gif,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

P52151WK 52" projection TV, no video

Is the audio coming from the TV's internal speakers, or from an external sound system? In the 169 series chassis, if the power supply caps or secondary rectifier are bad, or if the high voltage splitter has shorted inside, the set will not run and there will be no picture or sound from the TV. If the picture is completely black but the TV still has audio, press the menu button and see if the menu comes up on the screen. If the menu is there, check your cables on the back of the TV. If you are using a cable or satellite box, the box could be bad or the video wire could be bad or loose. If you do not get the on-screen menu, then I would guess that the solder joint next to the flyback transformer that sends filament (heater) voltage up to the picture tubes has cracked, or the low value resistor in the heater circuit has opened up. If that is the case, have the set serviced by a qualified tech familiar with the 169 series chassis.

Powers on, audio works, no video at all

First, need to narrow down the problem. Did you perhaps change the input source? To this point, change the input source, there should be text on screen that indicates what source is you see this? Change the you see the volume level bar on the screen?
