By 7045 cap 2061 and resistor 3148 and 7044 should be the only thing.

    If that don't correct the convergence replace the board they sit on.

No picture. Sound is OK on Philips DPTV345 model 51PW9303/17F


I would check the solder on the Vertical output IC as ofetn the soolder will crack and the CRts will shut down to prevent damageing the CRts when vertical drops out. If the solder looks good I would try replaceing the vertical IC very inexpensive and you can get the vertical IC from www.tvrepairworld.com

The manual converge is all unaligned and I can't get it back together and now I can't watch tv without seeing all colors


need to repair the comvergence ic , and maybe replace 2 resistor , this repair is about $250 , i would recomend u to hire a tv tech for this job , because after they replace the ic they may has to do some aligments

Convergence problem


There are 12 resistors all of them are 6.8 ohm 1watt resistors they are located in front of the ICs heat sinks at board location numbers 3149 -3160 they will all be identical and are grouped in sets of two side by side.

Color won't converge


This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!

Tv shows circular double lettering on the top and bottom of screen. what is wrong and how can i fix it


Your symptom sounds like a damaged convergence IC.


While it is not a very hard repair, this repair can be a bit tricky. If you have a 45W soldering iron, solder, solder wick, and heat sink2.gif compound you can repair it yourself.

When you remove the old IC's, please be sure to remove all of the old heat sink compound, as it can act as an insulation for the new IC's and cause them to overheat. I usually clean the heat sinks2.gif with alcohol and a small rag.

There are two and large IC’s that control the convergence in a big screen set. Some of the newer sets only have one. They are secured to a very large aluminum heat sink. They will have a part number stamped on them that will start with an STKXXX-XXX, like STK392-110, and they are located on the signal board (on the left as you look into the back of the set).

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.
There are also two resistors on the front of the board located in the middle that are fusible link resistors, these should be checked for opens and replaced if they are found so.

If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.
If you need further assistance please comment to this post and I will try to help you further.

Convergence will not line up after replacing ic & resistors


Did you replace the resistors when you replaced the convgence chips? If one of them was bad you would still have the problem.

Here are some of the most common symptoms and example photos.

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick email and they will put one together for you. Their kits includes photo instruction guides, original Sanyo STK chips, convergence resistors, pico fuses, etc.

BLOWN RESISTORS


you can download your schematic that will tell you resistor values and the rest of the circuits and IC indentifications as well as test procedures and more , this is a ten part zip that can be opened with winzip and read with adobe just click here http://www.eserviceinfo.com/downloadsm/12926/Hitachi_50FX30B.html
then to order resistors you can get them here http://www.nteinc.com/
or look for an electronic parts supply store around you , but alot of the time they too have to order the parts, ecspecially certain valued resistors or other special valued parts
if you need more help just ask !

You need to replace both convergence ICs they are STK392-120 and you will also need 4 of the 6.8 ohm 1watt resistors. You can get replacement ICs and resistors at the following link and they provide free instalation instructions with pictures.

Convergence Board


Have you tried just replacing the STKs? This set uses two STK392-120s I think.
