SOURCE: will not turn back on

Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine.

This is "NOT" meant as "expert" advice...as this is not my area...HOWEVER...I see no one has answered this yet...AND I got some good help from here a year or so ago that worked for me!

When I had a similar "green screen" problem with my SONY projection tv...the guy helped me by having me make "MINOR" adjustments to the red/blue/green etc knobs behind the panel. These were three small black plastic pieces and needed less than a 1/16 of an inch adjustment...try adjusting one at a time and giving it few seconds after each adjustment. It worked for me..at least for a while (till my wife gave it away to a friend because it was "too big"...ah! women!!! LOL)...hope this helps. (NON-expert help!)

Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem

  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.


Problem #2 CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Picture of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

SOURCE: WD-62525, continous amber lamp light. No picture. Lamp is good.

Hello:

Make sure u replace the lamp cover as the safety switch need to be closed to make the set work. If new lamp did not repair your problem , then it may well be the Ballast Board, Sometimes call the Lamp Driver.

Projection TV sets have two very common problems listed below.

Problem #1) 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

Turn the tv on picture come on all red and fuzzy and then couple seconds later tv turns off and then turns back on with no picture just red screen then turns off and wont turn back on for ten min


It indicates a short at the Red picture tube--set has three picture tubes and each has a socket which processes signal to each tube--each has a single IC chip---in your case either the chip on the red board or the red tube.

If a bright red screen the set will detect something is pulling way too much current and shut the set down for protection---called a shutdown circuit.......

Akai PT5598HDX/SMS won't turn on


Just a thaught, I could be wrong, maybe a problem with the power button on the remote ? It might shut the TV off, and when you do keep pressing the remote button, the red light on the TV will keep flashing like that also. Ive seen this prob on a few other blogs, so seems to be pretty common. I know I like to keep the remote pointed at the TV all the time, maybe try pointing it away for a while, just to see.
