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

Open Question

Lamp or Bulbs for a Sony KP-51HW40 CRT RPTV , The Red bulb is available but the green and blue bulbs are (what I was told) discontinued. They told me that there are 2 different serial numbers for that model number and the green and blue are in very limited supply for the one and discontinued for the other. I asked if the TV could be modified some how to accept a newer style bulb/lamp and I was told no. Do you have any solutions to find the correct bulbs?

I have never heard of two CRts being shorted at the same time. I would suggest calling another shop as They are most likely trying to take advantage of you. Go to the following link and leave an email indicating your model number and one of their techs will email you back and ask you to explain your symptoms.

SOURCE: KP-51HW40 Sony 51" Fades to blue screen

The service manual on page 8 shows how to adjust the Red/Blue/Green screen voltages. To get to the adjustment board, take the front speaker grill off (two screws at the bottom left and right) and set it aside. No need to disconnect any wires. Then remove the plywood board with 4 screws that exposes the screen/focus adjustments. The top 3 adjustments are for focus, and you need not mess with these. The bottom 3 adjustments are for Red/Blue/Green screen voltage rough adjustments. My screen showed red lines, so I had to turn the bottom right adjustment with a philips head screwdriver just slightly until the red gun retrace lines where no longer visible.

SOURCE: Sony - KP61XBR48. I need to know a model of the replacement Lamp

First of all, there are no lamps inside this set, there are CRTs. These are not just replaced as lamps would be. The CRTs themselves will run at leas $80 each. To change these will require replacing the coolant for the CRT as well which is not a DYI type of job. The coolant is dangerous and needs to be handled carefully. Also, once a CRT is replaced, a complete mechanical and electronic convergence adjustment must be made. There is a specific order in which to do this that is outlined in the service manual and it requires a template that would need to be purchased as well.

Unless there is a specific problem that needs to be addressed, it is unlikely that any of the CRTs needs to be replaced.

If you are having a problem with the set, can you please update this with a description of the problem? We should be able to assist in the resulution of the problem with something less drastic than CRT replacement.

Thanks,
Dan

How do i replace the bulbs for sony KP-51HW40 t.v.


You do not have any bulbs in this set. You have 3 CRT's. You can not get them anymore. You would have to pull all 3 out and send them in to have them rebuilt. For the cost of that, I would purchase a new TV.

All three bulbs are flasjing - color is washed out a bluish grey


The issue on these TV's is the CRT's are failing. This was a very common problem with these series of Sony projection TV's. The original CRT's are no longer available but there are suitable replacement CRT's, but they then all HAVE to be replaced at the same time. The part numbers are as follows for the new CRT's. Please take a few moments to rate my answer. Thanks...

GREEN CRT A-1502-025-A

Sony kp-51hw40 I need to know were the red crt is.


If you take the front cover off and look at the bulbs, you will be able to tell which one is the red bulb. Looking at the front of the TV, the red shhould be on the left. If you need a red bulb, I have one that works fine.
