Have You replaced the convergence ICs Yet? They are Big Black ICs and will have part number on them .
example STK392-110
Mats Electronics has ICs 1-800-628-1118

JVC AV-56WP30... | Answered on Jul 25, 2011


The set uses a pair of STK-392-110 convergence IC chips.

Fairly easy to get at in this model (I can tell you how) and if purchased on EBAY parts will cost less than 20 dollars.

They are soldered in but the board comes out fairly easy.

See attached photos of what convergence problem looks like and also a photo of a typical chip.

Hello
The audio output IC has some troube with it. if it overheat, the fault you describes here will coccur. Normally audio output IC will be screwed on to a metal heat sink to radiate heat away from it while working. If the screw that holds the IC to heatsink get loose, proper heat radiation won't take place, IC will overheat with time and will shut OFF by itself. Check the screw first. Resoder all the soldeer terminals of that IC, by applying a little more solder, without making any solder bridge in between the adjecent solder terminals. This process will eliminate if there is any loose soldering junctions to the terminals of that IC. If these does not help you, replace that IC with same type and number. OK.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....


  • Screen looks 3D, wavy, or has a shadow or shadows
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems.

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

If convergence is skewed in some area of the screen and will not adjust one of the two STK-392-110 convergence chips the set uses is bad.

See attached photos which show typical convergence problems and what the board in YOUR SET LOOKS LIKE.

This board is fairly easy to get at and the repair easy for a do it yourself person--I can tell you how to get it out and what is involved.

Total parts cost will be under 25 dollars on EBAY.

convergence issue. The JVC repair kit called the AV48wp30 - AV65WP30 convergence repair kit is the correct kit for your model and symptom. Its available from www.tvrepairworld.com and the kit contains the parts and the CD with repair instructions.

JVC AV-56WP30... | Answered on Feb 18, 2011


Maybe so. Convergence is generally controlled by two large ic's " chips" from the symptoms you describe the convergence ic or stk's as they are commonly called are possible blown. When these short generally that will lead to a shutdown. There could be additional problems as always. Cost are difficult to deternine depending on where you get your repair. If the chips are the problem they generally average about 25 to 50 apeice for the chips. Our shop generally charged about 150 to 200 for such a repair. My advice is it is cost affective to repair this set. .Note: when these ic's blown they can damage other components that might add to cost of repair.

this like problem from tv bulb, change it with new one

JVC AV-56WP30... | Answered on Jan 22, 2011


Oh dear, sounds like you have taken on a difficult job.

There is only need for two colours to be adjusted as the third colour remains static. I am at a loss as to recomend what the problem is except when soldering/de soldering unless you are using a static sensitive iron and conform to static protection, you may find that you are putting faults on the new Ic's as you fit them.
You have to fit new Ic's without damaging them with static.
If you remove the convergeance panel from the TV, place it on a bench that is of the same potential as your iron, that is the only way to guaratee that there will be no static damage.
The Ic's used use CMos technology and their inputs are highly sensitive.
When you get your system back as it was the colour that does not move stays static. Say green as that is the commom colour.
Cover the blue gun with a piece of paper/card to block the light and set the Red to meet the Green. Then cover the Red and do the same with the Blue. Now the Blue is more difficult to do because people see Blue from a TV in a differen way.
New/replacement panels are probbably not available but check ebay for an old unit if the board becomes unserviceable.
I hope that helps.

Ur tv have a problems known as a convergence problems,it dead.The tv have colors lines R,B,G mis alignments,have colors shadows pictures or 3D picture look alike?The tv convergence board it is dead.The tv convergence board,must require repalcing 2 STK convergence ICS and some or all of it resistors too.The tv convergence board is fix,will solved ur tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

JVC AV-56WP30... | Answered on Dec 04, 2010


Sounds like one of your convergence IC's has failed. One easy way to find out is to go into the menu and try and adjust the red if it wont move then its for sure defective. You called it a wave and the typical of convergence IC failure. Your set either has 2 or 3 convergence IC's and I would replace them all. If you can solder then you can do it yourself other wise call a tv shop and ask what they will charge to replace them.. there part numbers usually start with stk392-xxx take the back off and you can see them. They are about 3 inches wide and 2 inches tall and black.

Hello,
It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergnce select that and wait a minute the TV will adjust itself and give you a clear picture.
If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the curser (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It taked time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture.
You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch.
RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.Please run the convergence feature on your TV. Its giving you duble image because the red, green, and blue guns are disaligned. By running convergence it will realign the guns properly. You need to run the convergence feature at leat onece a week. Please note this is only for CRT rear projection tv's and I assumed it was. If it is an LCD rear projection, then there's nothing you can do to fix such thing, but call a repair person. But if doing the convergence doesn't fix the problem, you need to call a repair person. But I hope you won't have to. Please refere to your tv's manual on how to do converegence and how to overlap the crosses because every CRT projection tv is different.
Good luck

See attached photo of what convergence board in your set looks like and the chips that fail; it is directly behind front panel beneath the screen--access from the front.

I can tell you exactly how to get at it and what is involved in the repair---TOTAL PARTS COST ON EBAY will be under 25 dollars.


If you want assistance and this information and the photos helped you rate this solution as very helpful.

I have done dozens of these sets with the same problem.

Close up view of board from back, note the two black chips and the protect resistors in front of the.


Entire board is at front of set behind grill under screen, I can tell you the best way to get it out and do the fix.

JVC AV-56WP30... | Answered on Aug 22, 2010


Been there, done that---JVC remotes are very expensive. I repair these sets as a sideline and I have a Samsonite case full of remotes--get your hands on the correct remote--check the flea markets or even EBAY.

I have a 57 inch someone gave me, told them unless that included the remote, forget it (it was the only major remote I did not have) Most of the remotes are 50 dollars or more at the wholesale level--check out EBAY as I have seen them there for much less.

If you lived in San Diego, I would loan you mine.

If replacing the chips and the usual one resistor made it better you just have to get into the tech menu and adjust and SAVE the adjustments--in the customer menu it does not save and if power is interrupted it may go back to whatever it was before you adjusted it.

Let me know if I can be of any help--I am here to help and have a lot of experience with these sets. My hat is off to you--not everyone can do that repair (yes, it is easy as the chips are up front) and you just need to go one step further. The exact or correct remote will allow you to do other things.

What I do in my own situation is keep the original remote in my case and use a universal for basic things.

REGARDS, SD TECH
