Question about Hitachi 61SWX10B 61" Rear Projection Television

1 Answer

Hitachi 61SWX10B, convergence problem. Have read all similar problems and fixes on this site. The kits recommended have the STK-392-110 and RK's. The kits are not for my DP-17/13 they are for DP-14's and the resister values in the kits are not the same as what is on my PCB. Some fixes say use the 110's, some say to upgrade. I only want to purchase 1 kit, Please Help.

    We have the same problem with the color. Have had it fixed already two times under warranty. This will be the third time we will have to fix the same problem. -No Warranty left. How much will this cost?

I have red convergance problem.. This is the second time I have replaced all diodes and the stk chips. they dont have any 110 stk chips so i am using 150 stk chips. I replaced all diods and now RK 62...


Alot of techs recommend using the higher wattage ICs to replace the stock ones, which is never a good idea since the resistors get stressed. Upgrading to the STK394-160 IC is the only upgrade Hitachi recommends but then the values of the resistors need to be changed since the stock resistors will not work with the upgraded ICs

My 61swx10b the colors wont align the picture's bowed top & bottom & there is no sound


Ur tv convergence are dead.U must have a soldering iron and know how to solder to fix this problems.U must replaced 2 STk convergence ICS,and some or all it resistors.Tries websites like Tv repair World.com,Tvrepairkits.com to buy a convergence kit to repair it ur self.The shop will cost u $300-350 for parts and labors.

I have a hitachi 43FDX15B RPTV It appears to have a convergence problem, I've read about replacing the stk IC's but which resistors need to be replaced and what are the values on the DP15k/08 Board?


This model uses two of the STK-392-120 CHIPS and here are most of the usual resistors to suspect or check:

Hitachi AT03411S RK43 RESISTOR Hitachi AT03608S RP22 RESISTOR Hitachi AT03195S RK46,RK54, RK62 RESISTOR, 1.8OHM 1W Hitachi AT03857M R815,R865 RESISTOR, 1/2W 100 OHM Hitachi AT03191S RK50 RESISTOR, 1W 1.2 OHM Hitachi AT03197S RK50 RESISTOR, 1W 2.2 OHM Hitachi AT03199S RK41 RESISTOR, 2.7 OHM 1W Hitachi AT03202S RK42 RESISTOR, 3.3OHM 1W Hitachi AT03204S RK58 RESISTOR, 3.9 OHM 1 WATTThe RK ones are all marked on top and bottom of circuit board---usually if one is bad you will be able to see it is discolored---all are very low value and should read open or good only.

This is a fairly easy set to do this on---the whole convergence board (right side from the back view) is held in with 3 screws and an assortment of plugs--3 plugs are identical (convergence yokes and you need to mark so you get each back in same place)

A row of black snap plugs on the left side and with the screws and other plugs removed the board will lift up and out of the set.

DON'T waste your money on one of the "kits" being sold on the net---you can buy a pair of the chips for about 12 dollars on Ebay and usually only one (if any) of the resistors will be bad---those kits sound like a good idea but at 50-80 you are buying things you will not likely need to repair the set.

Let me know if you have any questions and if this information helped you rate this solution as I do this here for free.

As stated in your response to another person (Hitachi 43UWX10B)


Your post didn't get attached to the message in which you read the 'fix' for your set so the person who helped, will likely never see it.
You might try re-entering your brand/model info and sort through the results to find the original message.

Can't remember which this one uses but its right on the chips. Check your resistors too.

My color is off real green you do not see colors like purple and i see blue spots tv hitachi model 61swx10b v1k004865


Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in or warped.

Here is a quick test....

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

Try to adjust the 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.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.

Hitachi 65xwx20b convergence


Your message says you "replaced stk392-150", did you replace both of the stk`s or just one of them??? One is for RGB vertical the other is for RGB horizontal, you should always replace both stk`s as a set, Hitachi recommends you use a "replacement kit"
part number X480306", this kit includes both stk`s with a new & supposedly improved set of stk`s as well as all resistors that are required for proper set-up, they strongly recommend you change all of the parts in their kit. The only other thing besides IC`s & resistors that could cause your problem is:
1) bad dcu output (you need a scope to check this)
2) you`ve lost either the +15 volt line or the -15 volt line to the IC`s, "Fxxx" chemical fuse open in power supply.

Yes it certainly sounds like you have the old convergence outpuyt IC's that have gone bad in this TV set. If you have the soldering skills, and know how to work on printed circuit boards, you can repolace both of the STK convergence IC's. If you do not, you can get the complete convergence board at http://www.ptscorp.com, and the Hitachi board number is JT22056. Good Luck
