Question about JVC AV-56WP74 56" Rear Projection HDTV-Ready Television

2 Answers

My TV Hi There, When I turn on my TV, most of the time I see that half of the screen is green and other half is blue. I have to turn on & off the TV 50 to 100 times and play with "split" & "freeze" that cause suddenly the picture appear. I forgot to say that this green and blue on TV is shaky and some times it becomes some lines in different color patterns ( parallel lines ). When the picture comes it is excellent in quality. The problem is each time I want to turn on the TV, I have to sit down for 30 to 60 minutes and play with remote, and if I am lucky the pictures come on then. Please help me with this issue. Please tell me what is going on and what I have to do?????? Thanks

Thanks Easyab,

I am far from you, I am in Chicago.
I tought that might not be the conververgence. because when I want to watch TV, I turn on the TV and I do Auto Convergen once or twice. then I press Freeze or Split on my remote back and forth, and suddenly the picture comes in great quality ??????
I am a Canadian medical doctor ( recently moved here ) and I don't know much about TV. I accept what you say and I buy your words. I am very good with repairing things and I hope I will learn to repair this TV too without any damage to it. I asked some body to come and repair it. He asked me for $300 that is alot for me untill I begin my job.
Could you please tell me the cost of repair?
I don't know if I can ask you more questions when I go through those steps you mentioned????
my direct email is: drsnour@yahoo.com
Sincerely
Sam

Hey Zerp,

You need Convergence IC's. It is more difficult than batteries on a remote.

You access the convergence board through the inspection plate that is located behind the front speaker grill.

You remove the board, determine if any resistors are burnt, replace any burnt or out of tolerance resistors, replace 1 or 2 IC's and re-install the board.

Now you have to adjust it to look like new.

If you haven’t misadjusted it too badly, do the auto focus and it is back to where it was before IC failed. If it is still misadjusted badly, then resistors may be wrong value or open.

If you live around Calgary, try me instead:

Or try the find a repairperson part of this website, maybe you will be lucky and someone is listed nearby.

Most rookies doing this job will cause damage and not be successful, and pay double for someone to fix their mess or end up scrapping the TV.

try to go to the factory reset and see if that helps. If not, you can then check your connection. if you use component (red, green and blue for video and red and white for audio), make sure all the color matches when you plug it in. if everything have been checked then you need to replace the main board and it should correct the problem.

I have a problem with my picture


If convergence is intermittent, then most likely poor solder connection on convergence board. This is not a simple repair. Accessing the board, removing it, identifying the poor connections and soldering, then re-installing is delicate work.

If you are in Calgary, call me.
