Question about Sony KP-51WS500 51" Rear Projection Television

1 Answer


When i turn on my tv the picture looks great... for about 2-5 minutes. Then the screen will flash to blue over about 2 seconds.... then it shuts itself off.

Anyone ever have this problem before.

I bought this tv in 2002. I had the tubes replaced in 2006 while my warranty was still good.

If anyone can help me that would be great. It's $175 just to have someone come out and take a look!

Tv turns on w/pic then pic dissapears light blinks 4 times

I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.

the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.

A solution to this would be greatly appreciated.

TV screen Flashes blue and then shuts off.

When it flashes blue, are the flashes bright blue lines going across the screen with the picture in the background, if so, It sounds like the Blue tube or blue driver circuit is breaking down after a short period of time. If this is the case, the uPC that controls the set is detecting a large current drain on and is shutting the set off for protection, An engineers expert eye is required I`m afraid. Ian.

Our Mitsubishi WD 52525 goes to blue screen and shuts off.

It sounds like you TV is overheating and the video is suffering and the lamp is overheating as well. Also, if your TV is over 2-3 years old, the mirrors (behind and below the big front screen) desperately need to be cleaned. Clean all filters and fans as well. (Look on side and behind the unit). Is the TV in a "hot" environment and/or dirty environment? DLP TV's are NOT sealed units. They need to be cleaned every few years to work well to have a good, clear, bright picture.

Double and curved image on blue warm-up screen

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links 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

Green flashes then tv turns off

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Error Code 5 flashes when unit shuts down

Good Day;
It sounds like the TV may have a shorted CRT, picture tube, but let's trouble shoot:
1. Unplug TV from wall.
2. Remove speaker grill, two on bottom, the screws are covered with plastic caps, right and left side on bottom next to floor.
3. Remove inner panel.
4. The blue tube is the one the right side, remove socket, with phillips driver, make sure it's not touching anything.
5. Plug and turn TV back on, if picture appears with no blue it's the tube.
6. If still shuts down, bad blue CRT driver IC.
CAUTION: Call a factory authorized service dealer to give you an estimate, if this sounds too hard.
Good Luck, Day, Big Irish.

Sony tv red flashes

I hate to be the bearer of bad news, but you have a shorted red picture tube.It is not at all uncommon on sony rear projection. The gun shorts and the set identifies the problem and goes into shutdown. Usually there are diagonal lines in the picture before it shuts down. this is an unfortunate problem because this set delivers a great picture. The dealer cost of the tube is around $200. When the repair is complete your're probably looking at $400-$600. The only problem is that the green tube and the blue tube also have chance of having the same problem. It'a tough call . But from my experience , I have replaced the green tube and had the blue tube goe within a year. Scrivitron
