Sounds like your convergence outputs are bad and you may also have some low value resistors that need replaced. That set probably has 2 outputs. Both will need replaced even if only one is defective. Kinda like headlights, if one is bad, the other isn't far behind it. Excessive heat kills the amps after a few years of use.

Hi! I am experiencing the following three


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.

My screen has blue and red lines across it. Now the red lines are becoming stronger and the screen flashes red until it turns off. how do i fix this?


This is for if the lines are thin and in the form of an arc across the screen.

You need to turn down the screen voltage for the blue and red CRT. I believe the access is through the front on that model.

1) Remove the front grill
2) There should be access panel you need to remove once you remove the front grill. This is where the screen voltage adjustment is located
3) Look for a small black box with six knobs on it. One row is for "Focus" and one row is for "screen". It will be marked, but probably need a flashlight to see which row it is. There will be a "R", "G" and "B" next to each knob to represent Red, Green Blue respectively.

4) Careful with the access panel removed, you are only inches away from very dangerous voltages.
5) slowly turn the R or B knob counterclockwise until the lines on the screen disappear.
Keep your hands away from everything else and only use one hand near the tv. put the other hand behind your back.

6) Once corrected, replace the panel and put the grill cover back on.

Starting last night our tv has had a "ghost" thing


What you have is a very common convergence issue which could either be rather spendy if you take it to a technician like me. It usually costs approximately between $300-$400 if yo bring it to someone who knows what they are doing OR you could go to www.tvrepairkits.com and order the convergence repair kit for about $75-$80. Ed will set you up with the resistors, the integrated circuits, thermal paste, and step by step directions. It would take a novice about an hour and a half to complete the repair and you would save yourself some money. Sorry, there is no scan option to fix it.

Red, green, and blue rectangular "chads" or squares across top of screen


Hi there, this is easy thing to fix. Its LDV cable. This is the Cable which goes from the main board on to the screen. Un plug the cable from the screen side., then push the cable back. Make sure cable sits in .

This will sort all the problems with the picture,i.e colour problem , picutre squring up and many more things.
