I have a jvc av-65wp74 and I just replaced the ic804 and 805 with 150's and it fixed my convergence problem, but now every few minutes lines will come across the screen and the screen appears to shake or shutter. All of the resistor's look fine when I replaced ic804 and ic805. any ideas what the problem is?

i think my convergence is off . i have a red shadow behind the regular one. i went to the convergence part of my menu and there were 9 crosses. i couldnt get them to line up alot of red on the right hand side what do i need to do thank you .

I replaced the two STK392-110 with two STK392-150. Seemed to go fine but.... after plugging the board back in I turned the TV on and none of the laps turned on. You could here a ticking and then after several minutes the power button started to blink. Seemed to go into safe mode wouldn't allow me to do anything not even power it off. Didn't see any smoke which I guess is a good sign. Has anyone else come across this problem. Do you have any suggestion. Thanks in advance for your help.

Thanks so much Tracy and Eric for the schematics and guide. It worked perfectly. I ordered two 150s to replace the 110s ($21 with shipping) and bought a "5 piece basic soldering kit" from Radioshack for 7.99, some super thin 60/40 rosin solder and some desoldering braid. I have never soldered before this and I was able to do a clean job in about an hour. I suggest using desoldering braid (also called desoldering wick) for people who are new to the desoldering process as it was almost foolproof, very inexpensive (like $3) and requires no clean up. The only thing that confused me in the beginning was how to get the main Convergence board out from underneath the black plactic clips without breaking it (4 on one side and 1 on the other I believe). The trick is to pull all 4 clips back at once, lift up, and then pull the board horizontally out of place. I was a little afraid to do this in the beginning because the board seems fragile (so much weight with the 2 heatsinks and large components on top on such a thin board) but I was careful and it was no problem. My only question: now that the tv picture looks normal again with no crazy wavy red lines, it doesn't seem to be properly aligned. I have all perfectly white crosses on the 9 point convergence test, yet the picture seems a little sharp and jagged and maybe a hint overlapped (seen when looking at pure white lettering over black background in the beginning of a movie). Is there a more accurate convergence test I could do? Can I get rid of Velocity Scan Modulation and if so would the sharpness of the picture go away? I have ps2 hooked up through component cables and progressive scan enabled in the menu of compatible games and the picture still looks worse to me than a sdtv. Don't know what I'm doing wrong. Any help would still be appreciated.

Having the same problem as Tracy on 48WP30. Red wavy rainbow lines across top left of screen and a bit of shadowing. Eric- could you please send me the schematics and tell me how to fix this? Thanks a ton in advance!

This is the second time it has happened to me. How do I fix it myself? Thanks, Tom

I need the Instructions also.Could you please send them to me thanks alot.

Eric, Can you send me all information I need to repair my convergence problem on my JVC AV-48wp30 television please. Thank You, David

Hi can you help me I have shadows and red lines are showing with the shadow i have a 65 inch jvc screen tv someone told me it could be the convergence

Please send info to fix mine is out too. Thanks Dan
