Nothing that I know can corrected the problem.
if you wish, you can start by checking see if you get parts for the TV. I mean all of it. once you located the source, then I would start replace the main source of problem.
I would see the total replacements are more than the new TV cost.
it is your call.
I would just go buy a new one.

My Sony KP-46WT500 screen shows the tv image in blue only for a few seconds, then it goes completely blank (as if it were off). Do I need to replace the bulbs?


It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen.
Do you see standby red light blinking when TV shuts off after showing blue image for a while?
If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution.
Thanks.

When the TV is turned on it has a green picture and has lines running across the TV.


It looks like your TV has experienced a power surge (storm, power anomaly, etc.) and your main decoding and scanning circuitry is fried. You'll need to send it in for service.

Samsung HCN4226W "image pinching"


The convergence IC has gone out and is located on the Main bd or the Power supply bd depending on the specific model and must be replaced and a Full convergence alignment must be performed to return your tv to a watchable condition. Only a Samsung trained tech can do this.

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

Red,Blue,Green Image


YOu have convergence issues. Ok first question. IN your setup menu do you have the convergence option/ if you DO not then it can be a specail fusable link. fl231 if you do. next question do the picture bow in at the middle. if you do then it possibly a convergence power supply issue. next if you go into setup convergence does the crosshairs adjust up or down left to right on both blue and red. I if so then theres is a chance that it can be a convergence adjusment or a amplifer problem AS always THIS SET CAN GENERATE LEATHAL 380 VOLTS EVEN WITH SET UPLUGED SO BE CAREFULL.

Pt5598 rplaced convergence board no luck.


If the picture is still bowed, the power supply fuses are open.
Check the power supply on the red connector for + and - 20 volts.

The fuses are on the main board,are on the deflection module in the middle, tward the front of the TV. They should look like green (or brown) resistors. An ohmmeter check will show which ones are bad.
They should be 3.5 amps. Replace with 4 ohm GMA fuses with pigtails if you can't find picofuses. I also had a set that would fry the 1 ohm resistor on the 20 v supply. This was near the fuses.
I replaced the whole module to fix that.

I hope this helps. Lee, www.crazycomputers.com

Green ctr


Locate the screen drive controls, usually under the back panel above the main board, attached to the frame. There should be an adjustment for each color. Note the position of the green screen drive. Turn up the drive and see what happens. If you now have green your drive just needed adjusted. If nothing changes then you should remove the green crt board from the crt and replace it with either the blue or red crt board. If the crt displays an image the problem is in the green drive circuitry. If there is no picture you probably have a defective green crt. Usually it is not worth replacing the crt due to cost, etc. If you have the skills to perform these diagnostics good luck and remember safety. If not you will need to find a tech or shop to do it.
