Make sure that the bulb you have replaced is a genuine factory replacement. If its of a higher wattage than the previous one and is drawing more power from the ballast then the protection circuitry will kick in and turn off the tv to prevent damage.

Sai.

Hi


Thanks for using FixYa. From what you have described it seems that you have to replace the convergence IC and check power resistor for leakage, if values are not exact you have to replace them. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. Replacing only the IC's MAY solve the problem; however, many people have also had blown resistors requiring replacement. Why would you ask should you replace both of the IC's if only one is shot?! If one is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do rate the solution if the issue is resolved or else revert for further assistance.


Thanks

please read your owners manual for the samsung ptv to determine the best input to use and possible proper settings to adjust in your menu's.

STK ICs they are big black ICs will have Part number on them example STK392-020 also 2 resistors near ICs 2.7ohms most of the time they are Bad Call Mats Electronics for Parts 1-800-628-1118

go to samsung.com/us and look for downloads.

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!

i

If you hear like whirling sound and vibration on the TV,it looks like the color wheel bearing is loosing balance and is hitting the housing unit,the color wheel spins @ 5000 rpm you will definitely notice when is going off i have this link that i found i hope it helps http://guides.fixyourdlp.com/samsung/bp96-01579a.php?click=52978 it's not your TV model but at least you will have and idea of what you need to look for.

good luck

Please check +20 volt and -20 volt supply at CNZ03 (4 pin connector) in convergence board, coming from power supply. If any of them is missing, check pico fuses in power supply board.
Let me know your finding to move to next step.
Thanks.

your comverganc amp have failed they are stk392-110 there are 2 have a tech replace them

you have an overheat problem somewhere on one of the pc boards and the thermosistor is sutting it downfor safety you need a pro to service it sorry

Your symptom sounds like a damaged convergence IC.

There are two and large IC’s that control the convergence in a big screen set. 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.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


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.

It will be the one that has big black ICs STK394-020 for Parts callMats 1-800-628-1118 also there is 2 resistors 2.7 ohm near STKs replace if Bad.

Samsung HCL4715W... | Answered on Sep 25, 2009


No you have 2 convergence ICs replace them if you havent and look for burt resistors near ICs 2.7ohms most of the time 2 of them need to be replaced They are Big Black ICs will have part# on them STK392-020s order parts from Mats 1-800-628-1118

Samsung HCL4715W... | Answered on Sep 16, 2009


This is a common problem. Your convergence has gone out.

Common symptoms are...

1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly.

What do you mean by running slowly?

Samsung HCL4715W... | Answered on Aug 29, 2009


has a very different problem because if the fuse does not ignite the fuse you have to do is check voltages with a manual of your computer
