Philips 55P8342 Bow in picture

I have a Philips 55P8342. When you first turn it on for 10 secs there is a red,blue and green bow at the top of the screen about six to eight inches down. When the picture comes on the bow is gone. Any ideas I have replaced the convergence ICs. Thanks.

Replacement IC's suspect...did you use generic ? For all my repairs where originals are STK392-110,120 or 150....I use the
up-grade STK394-160E Mfr by SANYO with Hitachi part number
CZ 01341...they are expensive,but NO RE-CALLS ! Also,did
you check the resistors close to the IC's for over-heat damage ?

I believe its the vertical output IC. Diodes would tend to blow fuses . I would replace the vertical output and see if that takes care of the problem.

are you getting sound, was it moved laterly, did you just get it from somone, did it get wet, does it make clicking noises, was the picture color/ convergence blurring before this, were the colors slowly seperating such as red/blue/green?, did the picture bow on top and bottom or sides prior to tihs, was there anything note worthy prior to the blank screen.

generally its IC convergence problem with the larger philips projection TV's however I need more info on your TV, also size make model # anything you can provide gets us a more narrowed solution.

hope this helps....

Double focused, red and green, bow in picture top and bottom


hi
You have a convergence problem
If the set has auto focus and will not complete its cycle.
The Auto focus module is bad, (expensive)
If it completes and the problem is still there.
Then check for bad conv. drivers (stk****) or cold solder joint on one or more of the 3 drivers pins.

Tv is messed up


I got a question.

Do you have any stereo speakers anywhere near your television?

This sounds like something a magnetic field could cause from speakers being too close to the tv.

If so try to relocate them and see if the problem goes away.

Sounds like you may need the convergence amps changed and also resistors in that area and maybe fuses.
