Question about Sony KP-51HW40 51" Rear Projection Television

2 Answers

Red Screen I read through all the questions and responses and couldn't find the same problem my tv is having. the entire screen is red when i turn it on, i can faintly make out the menu screen, the color and brightness controls don't do a thing. i tried resetting and unplugging the tv for 15minutes and that didn't help at all

    Arched, thin red lines. However recently, after TV is turned on, it slowly fades to ALL red then turns itself off. Stand-by light blinks 5 times. When the ALL red event first happened, It was proceeded by a slight audible "pop" sound.

SOURCE: Red Screen

There is some information on how to fix the failure on your TV. Click here to find the how is done, but be very careful about the high voltages surrounding the circuitry. If the adjustments do not work then you could probably will have a defective red tube or a video amplifier IC on the red CRT board.
Let me know if you need further assistance.

51F59A red screen all the time


1. entire grill below front screen must come off (usually held in place by screws in back on either side.)

2. locate and remove inspection plate dead center behind it.

3. Locate small black plastic block with 6 black controls built in; three (look carefully) left to right are focus--DO NOT TOUCH THOSE.

The other three are Screens and will be marked with tiny letters r g b (red, green, blue) and green is always middle.

Locate the red screen (not FOCUS).

With set on adjust red down just slightly(usually less than 1/8 turn.

Since the set will be on TAKE CARE NOT TO TOUCH ANYTHING INSIDE THE SET WHEN YOU DO THIS.

IF YOU HAVE QUESTIONS ASK BEFORE YOU TRY THIS.

Screen is red with lines when channel is changed


If its a kp-51hw40 : go to an unused video input and look at the screen---if it is redish in the background with curved faint trace lines you have one of two things wrong; First: the red "screen" control may be set too high. Second: you may have a problem with the RED picture tube.


To try to adjust the RED screen down you have to remove the entire front grill plate on the front of the TV(some have screws on the back on either side that have to be removed---and then you should be able to pop it out. Behind it there is a masonite inspection plate held in with screws----Once you have that off look for a SMALL SQUARE BLACK PLASTIC BLOCK; it has 6 black adjustable controls---you have to use a flashlight and look carefully---one row left to right will be marked FOCUS--DON'T TOUCH THOSE---THE OTHER ROW left to right will be marked SCREEN; if you look carefully you will see marked by each r (red) g (Green) b (blue)
you want to locate the RED SCREEN CONTROL.

WITH the set still on a blank video input where you can see it clearly turn the RED Screen Control to the left until the lines and red tint go away---do this slowly and make sure you are adjusting the RED screen--not the FOCUS.


IF this has been helpful give me a vote here as I do this for free; yesterday I adjusted one of these in a home that was blue with the faint lines---about 15 minute job for me.

The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?

Yes the red tube is shorted. I will post a link to the site where I work as they have an entire AV48WP30 with a bad tuner they are selling parts off of including the Tubes. they also provide free info on how to switch out the tubes as a unit which is a fairly easy job. Heres the link.

Red CRT is dim....


Yes I did. You will need to get a service manual for this TV set to trace the voltage coming from the sweep power supply. If this is a problem that is new after you replaced the convergenbce4 board, you for sure have a broken wire or connection somewhere in the set. Have seen this happen may many times after a novice repairs a TV set. Good Luck
