    we got the modules removed once i clean with alcohol, if i do not have the heathsink compound is it going to do any damage to the new parts or tv if we use it tonight, where can i get the compound?

  • mcojg5 Nov 18, 2009

    we did all that but hte picture is still a little unclear and has a little shadow or aura as i call it. any suggestions.

  • mcojg5 Nov 18, 2009

    tried to fix with flash focus and didn't work, checked on menu with the controller and couldn't find anything for alignment. ANy other ideas where we could check or try?

  • mcojg5 Nov 18, 2009

    it is a Sony 65 in rear projection the model number I have is HP65WS500, hope that helps

  • mcojg5 Nov 19, 2009

    yes it did make a difference and it is the same in both modes.

  • mcojg5 Nov 20, 2009

    was just wondering if you found the steps and procedure to re-align 65 in Sony rear projection for new convergence chips?

  • mcojg5 Nov 20, 2009

    that is fine what evere you think is best

  • mcojg5 Nov 22, 2009

    was wondering if you got those instructions on the alignment yet?

First you want to make sure you removed solder from every pins of the module(chip) on the p.c board. What happens now is that the convergence modules are mounted on the heatsink with compound pasted at the back(heathsink compound) and after a while it dries up and forms a cement, you`ll have to pry or wiggle the modules away from the heathsink , once that is done you`ll want to clean the old compound using acetone or alcohol because that stuff now act as an insulator. It would be a good idea to get a tube of it(heathsink compound) and smear the back of the modules before mounting them securely.
Hope this will help. Good luck

    Just make sure the module is screwed on tight and it should be o.k.
    I`ve seen some case where they didn`t use any compound at all.

  • Jacques Marin
    Jacques Marin Nov 18, 2009

    You probably can get the compound from the same place where you got the modules.
    Otherwise just about any electronic parts supplier near you.

  • Jacques Marin
    Jacques Marin Nov 18, 2009

    Often when you replace those modules, the set will need convergence adjustment, if you go to the menu(video or setup) there should be an alignment procedure.Try it and you should be able to bring it back to acceptable, that is if the convergence circuit is in working order.


    I mean that often there will be resistors that will go faulty along with the modules.
    In that case you might not be able to bring it back.
    You also might have a function like magic focus that will do the trick.




    Keep me posted

    Pretty much all modern projection tv have some sort of convergence alignment in their menu.
    Let me have the make and model# of your tv, and i`ll get back to you on that.

  • Jacques Marin
    Jacques Marin Nov 19, 2009

    You`re right, in sony tvs there is nothing in the menu that can help us.
    What i`d like to know now is did the replacement modules made any differences/improvement or is it just as it was before ??? And is the convergence the same in wide or standard mode???


    Now the next step is a tricky one. You`ll have to get into the service menu and bring up the convergence setup menu.Since i`m at home right now and it`s been a month or two since i last converged a sony wide screen , i`ll have to get back to you with all the steps and procedures.

  • Jacques Marin
    Jacques Marin Nov 20, 2009

    Sorry for the delay but i should be able to get back to you on that sometime this evening , depending on your timezone.
    It could be handy if i could email some of it to you.
    Then we could go through it together.

Ion block rocker won't hold a charge


Yes you can! I just did today. You need a philips screw driver.
If you have the white ion Block Rocker, find the access panel to the battery on the side of the device, (Facing the speaker it's the side to the left).
I suggest using a kitchen counter, island, tool bench for doing this job.
1. There is a simple 4 screw access door. Find it (opposite the side that has the charge lights and power switch).
2. Remove the screws, put in cup or saucer.
3. The door itself is super tight fitting, and you will need to turn the box on its side, battery door facing down, and gently bounce/tap/knock the device to work the door out were you can grab it with finger nails and work it open. (Gentle and patient but purposeful drops from an inch or so, no more, checking each time to see if the door opens. You don't want to damage the equipment. Pull out door and set aside.
4. Battery is also super tight in the access and suggest the same method until you can get some fingers on on the battery and work it out. I had to uncouple the horseshoe connectors + and 1 from the battery before i could pull the battery completely out.
5. Go to Battery PLUS, or Radio Shack with the battery in hand, to ensure you get the right one. SIZE MATTERS IT MUST BE EXACT. get a new one and RECYCLE THE OLD BATTERY with the store.
Follow reverse order to install.
Good Luck and let me know if it works. Dave S. Show Less

My panasonic PT-47wxc43g projection tv has developed shrinkage in the middle of the screen on both the top and bottom. The picture has an hourglass on its side appearance. The picture is now also too large...


This could be a problem in the convergence board which will cost of repair would range 400.00 or so.
You can get the convergence repair kit at the following link which contains the parts and step by step detailed instructions.

How do you take apart a ryobi lithium 18v one battery


This applies to Li-ion. NiCd is probably somewhat different.


Unscrew four security screws on the bottom of the battery. If you don't have the right bit you can grind down the center pins in the screw heads and use a T15 bit.


Unscrew the hex-head screw in the center of the protruding post at the top of the battery. It may be non-standard in size but a small metric hex key wrench works if you are gentle. The four corners of the battery cover should be loose now.


There are still two plastic clips holding the top cover to the main unit near the centers of the long dimensions. Gently push a knife blade into the crack between bottom and top to release the clip on each side.


As you lift the top cover off you should push down on the contacts near the top of the post so you don't pull on the attaching wires. Eventually the contacts should pop free and the top cover detaches.


Detach the wiring harness for the status LED from the circuit board. You can now remove the combined circuit board and battery pack from the lower case.


Six screws attach the circuit board to the battery assembly, along with several solder connections, but you probably don't need to go this far. You can now test and possibly replace individual cells.

Can i purchase a needle for the ION ITTUSB ?


Yes but it is not the needle you would buy (ah in the old days it was a needle) but a cartridge

The user manual available here gives you a little more detail.

It is sometimes possible to get the needle assembly for the more expesive cartridges but yoy would need to know the cartridge make and model for that.

If you unscrew the headshell locking ring on the tone arm you can remove the cartridge by pulling it out (hold the arm and the headshell doing this)

This would give you a better idea of the cartridge make and model and also allow you to see how it is mounted (2 screws) to the headshell.

Batterys


  1. Order a new battery. http://www.all-battery.com/ It was LG Li-Ion 18650 3.7V 2400 mAh Rechargeable Battery with Tabs. Original battery is 1,800 mAh so the replacement should last longer.
  2. Take the screen cover (faceplate) off and unscrew 4 screws. You will need small Philips head screwdriver.
  3. Pull off the front of the GPS. Be carefull with the GPS antenna. Make sure you remember its position so it is easier for you to assemble it later.
  4. Unscrew 2 small screws holding metal battery retainer strip. The battery is behind it. Pull battery out and disconnect it from the board.
  5. Cut the heat shrink tube the battery is in and de-solder the joint.
  6. Solder new battery. A small 15W soldering iron will do the job perfectly. Make sure not to overheat the battery.
  7. Insulate the solder joints.
  8. Put the new battery inside a heat shrink tube. You can get it from HomeDepot. It is ¾ inch diameter.
  9. Use a heat source (I used a gas lighter) to “shrink” the tube. Again be careful not to overheat the battery as it may explode.
  10. Put battery back into instrument and screw the metal band back onto the battery.
  11. Assemble everything back together.
*NOTE* Lithium Ion batterys do not take heat well. Leaving your GPS unit on the dash on hot sunny days will decrease its expected lifespan.
