Hi Rafael,

First of all thank you for posting your question here at Fixya.
Please confirm if the brand and model number above is correct.
Blinking of the the LED (yellow and blue) at the front panel indicating that the lamp door cover is not seated properly. This cover will engaged to a micro switch giving the signal to the processor, once it is in open position, the unit will not power up and will experienced that kind of blinking error code. Go back to the lamp door cover and ensure that it is properly seat-in.
3D, 2D, red/green/blue ghost on the picture and letters means that the convergence circuitry gone bad. Symptoms is not connected to the light engine. The faulty parts is the convergence chips(IC). This chips are mounted on the large aluminum heat sink and starts with STKXXXX-XX (X means number). The most common STK chips used on Projection TV's is the STK392-110. You have to replaced them both on the board to resolve the issue(red ghosting). It is necessary also to check the resistance value of the resistors around its circuitry using the multimeter. For more info how to repair a convergence problem, watch the video below.

Akai PT5598HDI Rear Screen Projection TV With Blue Shadowing


If the ghosting is like a 3D effect its your convergence ICs , but if its like a blue Halo around objects that usually means your CRT coolant has congealed and will need replacement. The blue is the first tube to congeal for some reason, followed by green. Red seems to be not quite as prone to this. It is a normal occurrence n sets about 4 years old to need the coolant changed.

Model 50UX58K - picture has distortion & shadow on right side of screen


Hi, if the shadow is colored lines then you probably need the convergence ICs and possible reisitors near them replaced .
If the shadows is just like a ghost of the image or a bar from top to bottom, then check if it does it on every input (dvd for example) , there are blanking bars that you can't see past the edges of the picture and when you have a bad cable signal you can see the ghost of the blanking bar sometimes. if it does it does not show the shadow when watching a DVD then its a signal issue with your cable/satelitte .
If your convergence is the issue, try the adjustments first and if that doesn't correct it, you can replace the ICs using kit # x480293 or stk392-110 (2 ICs) soldered in very technical for even a technician.
repairman cost about $250-$350
hope this helps

Tv duplicate image


your guns are off and need to be adjusted. your 3 guns (red, green and blue) are off and that would explain the funny colors and shadows. Have a tv tech come out and have a look, they can fix it for a reasonable price.

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.
