Sounds lke it may be heat related. You can get a can of what is called freeze spray and heatgun(or hairdryer) and try heating and cooling sections of the modules to see if you can isolate the problem. Also sounds like you may have a loose connection. Try tapping around in the set w/ something non conductive such as a screw driver handle, to see if it will act up that way. If I was working on the set, this is where I would start. Heat related problems can be agrevating sometimes to find the correct component. Good luck!

The tv have a problems known as Convergence problems,it dead.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead.These parts must be replaced to solved the convergence problems.The shop will cost u $300-350 for parts and labors.

Your bulb is blown and must be replaced. J.

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some photos of convergence problems.






Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

Unfortunately, there isn't a code we can provide. Try your universal remote's scan or learning feature to find a code.

Projection sets have two very common problems.

The first common problem is convergence


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,Akai,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...

*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

You can see some more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

You will need a converter box or a separate tuner. The TV has an NTSC (analog) tuner.

I hope this helps.

(the $40 boxes that are available are mostly SD. You should check the specs if you want a HD tuner.)

This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Check the Components received are compatible with manufacturers numbers or if they are generic the voltage,ohmage,ampage and resistance must be almost the same.

Using a multimeter take out and test each individual components.They could have sent you faulty parts.

Ensure you follow the instructions very carefully when soldering them onto the board.

Hope this helps you

If your laptop has an S-Video output you should be able to connect your TV with the S-Video input (F connector) in the rear. You should be able to watch dvd and hulu if you have a good graphic card. But if you are looking to have something more permanent, I would recommend you a network-ready HD media player, like for example the Western Digital USB 2.0 WD TV Live Network-Ready HD Media Player. I have one of those and I can see HD movies that I download and put on my Usb, or I can see any media (videos, photos, music) that I have on any hard disk in the network. (Because the media player is connected to my router) The media player can work wireless if you install and additional wireless adapter. If your media player is Hulu-ready, you will see it immediately. The WD TV Live only has Youtube integrated. In my house, I converted my laptop in a Media Server with PlayOn and I can stream Hulu, CBC, CNN, etc. to my WD media player (in my case, wireless, but I want to connect them directly) and then to my TV (using a hdmi cable, you can also use a composite cable) It is about $230 in components: Media player ? around $130 Compatible wireless adapter ? 40$ (optional) PlayOn ? 40$ Cables and others ? 20$

Sounds like loose solder on the chips. Either that or they are failing. You can save money next time by doing it yourself with a kit from www.TvRepairKits.com

No, you do not need convert box if your TV says HD on it!

YOU HAVE A CONVERGENCE PROBLEM. THE RED OUTPUT IS OUT. COMMONLY IT HAS BEEN FOUND TO BE THE DIGITAL CONTROLLER MODULE THET CAUSES THIS BUT THE OUTPUT IC SHOULD BE CHECKED FIRST
