Hi,

a) your 50DX01B TV might be having a component failure .

b) typical voltages and test points are stated in the service manual,

have someone helped you measure output voltages first on the

power supply unit.

c) if you intend to " DIY " the service manual can be accessed,

details

d) it doesn't necessarily mean to get it but if we ever have a hard

time pointing out, where the problem might be, we will be all

basing on the specs of the service manual.


e) if it is totally having no power then most probably , it is on the

power supply, a good visual and voltage measurement is

needed to complete the initial diagnosis of your TV.


f) one such example is having a burnt components, please

include the chassis number so that i can help you more.

or describe the components if you have saw it failed.

The power supply will have to be replaced. You can test it if you wish with a voltmeter and the wires from power supply to circuit board. Should be between 12-13.5. too high or too low is bad.

My colors are not blending correctly anymore. My green is giving me a double picture. I have tried to blend them on the front and back but not luck. I need help


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • 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.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Picture will not come on


A few questions and a suggestion:

Do you get sound? Does power light stay on?

suggestion:

Unplug set and remove back cover---set will have several green led lights on board in power supply and one red one.

Red one should be on. While looking from the back have someone turn set on---note if all the green led lights come on and if one or more go off before the others you have located your problem.

The green LED's monitor voltage sources in the set's power supply.

I have more ideas but need more info from you.

If this helps rate this solution as very helpful as I do this here for free.

Had the same issue, I replaced two 1200uf caps on the power supply board and now it works fine again. Remember to replace the caps with caps rated for at least 35wvdc.
