I have a Samsung Rear Projection TV with a red convergence problem. Will replacing the deflection board fix this problem?

Hi,
This problem is due to convergence output ICs failure and both chips will be replaced to fix the issue.
There are two big black ICs installed with aluminum heat sink on deflection board, these are convergence output ICs and will be replaced to correct the problem, it is common problem of rear projection tv.
Below image of deflection shows ICs (marked in red) that are need to be replaced.
IC number is STK392-110 and available with Part Store for $32 each.
Click above link to see an image of IC.
If you are handy with electronics stuff repair and can replace parts in tv circuit board then can replace these parts yourself or ask local tech to help you.
Hope these info will help you.
Let me know if you have additional question.
Thanks.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

There is a problem on the deflection board (BP94-00501B). I have tried replacing the flyback, both convergence IC's and the horizontal output transistor without any luck. I finally bought the whole board from encompass parts for ~$120. Hope this helps.

sounds like the convergence chip. i think you can get a kit from tvrepairkits.com not sure how much it would be to have fixed. But if your good with a soldering iron i think their kits come with instructions as well.

Hi, this TV is repairable and you will have to replace two devices. the first is the Convergence board. this device regulates the convergence of the RGB stream so it can be projected evenly. it works in conjunction with the CRT's and deflection assembly and the Focus pack(module). The second device that will need to be replaced is the Focus pack(module). This module is malfunctioning and is causing the smudges and warped look at this time.

Replace these two devices and it will fix this set. i will post the Part numbers below along with there respective prices as well.

Focus Pack(module).--- Part Number-- BP59-00005A--- $38.95


Convergence Board assembly--Part Number---BP94-00383A---- $165.95

Please rate and god bless:)

it has no relation to your putting in a blue cable. It's just died.

You will not find the problem in deflection board it will go back to convergence board,I repaired one that would not Magic focus cause was on connectors from power board to convergence board the one closes to up front of board one of the pinns was bent under so when i pluged it back in did not know after lifting up connector under tiny pins 1 of them was bend under straighten it so it could plug in right Fixed problem.

Your convergence ICs are defective and quite possibly the burning smell was likely some of the convergence Resistors burning. Its actually not that exspensive of a repair. you can get a brand new Sub deflection board for your set for 232.00 at the following link and that will fix your set and you just put the new board in. The site will also provide you with free on line tech support to assist you with installing the new board. you need the P54 Sub deflection board. Its available at the following link.

If the new sub board didnt fix the problem you will need a new convergence board as the sub deflection boards with the ICs only powers the convergence board. thats a complete seperate board. Let me know if you need more assistance.

Your problem could be the Convergence board is loading down the power supplies and will not let the TV set come on, or the power/deflection board, part number AA94-08574A, or the STR type regulator IC, part number AA13-00105A. If you locate the convergence board, unplug the connectors, and see if the set will come on. if the set does come on, replace both of the STK convergence IC's at once. The part numbers for those IC's are STK392-40. You can get the original replacement IC's from MCM electronics for about 15 to 16 bucks a piece. Do not use the less expensive STK IC's as they are not the same. the replacement IC's should have the name of SANYO printed right on the face of the IC's. Good Luck
