No picture loud ticking noise like a alarm clock

A common problem for these is bad capacitors in the power supply, Remove the back from your TV and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this help in solving the problem....

Picture problem

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 projeciton 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.

It sounds like your high voltage block is arcing and causing the TV to go into protection shutdown temporarily. If that's the case, you'll most likely need to replace that HVB.
The other thing it could be if you're hearing "popping" (snapping ?), is that one of the CRTs could be arcing to ground, maybe the green one since you're getting too much green.
Good luck.

To much blue in screen and lighter colors are bright

Caution: you need the "O' ring kits for all 3 guns. If you can take the front off you can look into the lens and possibly see white stuff. If it's clear, it's not the fluid. If you see floaters, than the fluid is contaminated, usually from the factory or a prior repair? The Gasket kits come with instructions, most of the time. The repair manual is close to $100.00 so If your gonna dig in be ready for anything, especially if you've never done it before. PS: The 450 is a good price...

No sound

Get an external sound system! :-D

Although I highly recommend you get an external system, you will also want a backup system. Sounds like an electrical problem to me. There would be like fifty things to check, electronically. If you are good with electronics, like you actually have a multimeter and soldering iron laying around and know how to use them, it might behoove you to buy or download the service manual for your set.

Or call a pro to fix it, for the cost of which you could buy a cheap home-theater-in-a-box sound system. I recommend Yamaha.

Red and green do not light up

Start by raising the screen control for the red and green to see if they have any type of luminance.

Your red CRT socket may be loose or have cracked solder if not, try turning down the red gun screen control inside the set just a little. Youre experienceing what is known as retrace lines
