Re: burnt resistors

Resistor 3156 is SSM CBA to ground from Conv power packs 7045. replace both convergance power packs gen part # stk392-120 res 3164 is 100 ohm OK.

What caused the resistors to burn?? Have you already fixed

that? If so, what exactly was it ???   let me know...T.

How do you fix the color to a model 43fdx11b hitachi

Hello!you mean: colors out of convergence? nothing you can do about that, unless you replace 2 convergence amplifiers I.C. chips, plus all those burned 1 watt low ohms resistors with exact values, which only could be obtained via service manual or schematics. After resistor is burned, there is no way to read color code properly, due to partial evaporation of pigments. this is a "pro" job. If you try or tried, already to converge those "stubborn" crosses, there is more to do, even after you removed and replaced two 20 pin I.C. chips, soldered dead into sweep module, plus located and replaced resistors with precise values, you need to get your settings back to normal, by going into "factory service mode' or, at least into "convergence alignment" menu and fight with those crosses!Don't forget the white "****"! Otherwise, you will be re-servicing your set all over after 30 days of usage.good luck,Alex.

Colors out of alignment; curved lines

Marilee, you will need to check on the service manual schematic of what types of voltages you have on the IC's now. Most of the time, there are whats called pico fuses that blow out when the convergence IC's blow out. They are located on the G board, and are yellow in color. They look like small resistors. Check them for continuity after you replace the IC's. By the way, did you use good replacement IC's for the convergence? There are all sorts of aftermarket types and factory rejects being sold out there via the web or from local electronic parts distributors. Make sure they are the original types. If you know how to read a schematic diagram, but do not have the service manual, let me know, leave an e-mail address, and I will be happy to send you some info on the replacement of the ICs as well as the factory service manual. Good Luck!

Hello, This is your classic convergence Amplifier IC problem. Here is a way to deal with it. These are generic instrustions: 1) Get the schematic/service manual for this TV (You will need it because it contains the part numbers and component values you will need for replacement) 2) On the schematic/service manual locate the convergence amplifiers (STK392-110, 120, 150) and the biasing resistors (Write the resistor values down from the schematic) 3) Unplug the TV and remove the rear cover to expose the electronic circuitry. 4) Using the schematic/service manual find the physical location of the two convergence amplifiers (Usually attached to a big metal silver in color heat sink) (Basically it will look like two big black six sided flat modules with a lot of pins on the bottom (18-22 to be exact)). 5) After finding the heat sink and amplifiers remove the screws or the tension bar holding the amplifiers in place. 6) Using a soldering iron and a de-soldering device (either a de-soldering pump or de-soldering wick) remove the solder from the pins of the amplifiers and biasing resistors that protrude from the solder side of the circuit board. (Take into mind that you may have to remove the board in order to do this, use the instructions in the schematic/service manual to do this, and make sure you mark everything you remove to make sure you have a guide as to how to put it back) 7) After removing the solder from the pins off the amplifiers and the biasing resistors, remove the resistors making a list of the value, part number, and location on the board (all of this should be in the schematic/service manual). Then remove the two convergence amplifier modules taking care so as not to damage the circuit board. NOTE: The heat sink compound (the white goopy stuff) may have hardened and caused the module to stick to the heat sink, you will have to gently pry the module away from the heat sink, I have used a light application of isopropyl alcohol to dissolve the heat sink paste. 8) Once the modules are loose from the heat sink, you can gradually remove them from the circuit board. 9) Clean the heat sink off by using the alcohol and a heavy paper towel (remove all of the heat sink paste, and yes this is messy) At this point you have removed the two convergence amplifier modules and the biasing resistors and cleaned the heat sink. Now you will have to use your schematic/service manual to find the part locations, values and numbers you will need to replace the old parts I suggest replacing the biasing resistors first. 1) Sort out the resistors you will need and as stated in the schematic/service manual and replace them according to the schematic/service manual locations and part numbers. 2) Solder the components (resistors) in place making sure not to short out anything in the process. 3) Apply heat sink paste to the metal side of the modules one at a time and the put the modules into the circuit board lining up the screw holes of the modules with the screw holes in the heat sink, use the removed screws or tension bar to hold the modules down once in place in the circuit board and on the heat sink. 4) Solder the pins of both amplifier modules to the circuit board, taking care not to short out anything. 5) Reinstall the board to the TV, reconnect all cables removed (DOUBLE CHECK EVERYTHING) If all went well the convergence amps should be working, and you will need to realign the convergence of your TV, I suggest using the AUTO Convergence feature of your TV (Use the instructions in the schematic/service manual). All should be good now. Now these instructions are generic in nature but can be use for a number of Models of Projection TVs. In addition to this also make sure your Yoke transformers on your CRTs are functioning as they should, check the voltages applied to them. I hope this helps, Thank you, Shuttle83

I need to identify the parameters (rating) of a resistor for a Panasonic PT53WX53G projector big screen tv. It got hot so I can not see the color codes on it. This resistor glows red when TV is turned...

The resistor you see is a 2.2 ohm 2 watt resistor and is part of the convergence circuitry. I would replace R7011. 7012, 7013, 7014, 7015 & 7016 (all the same value) and the 2 STK392-110 Convergence ICs. This should fix your problem. You can find kits on-line for around $45 with the IC's and resistors together.

They are parallel in circuit and measure around 2 ohms when ok. Check the fuse associated with that circuit. FD101S 3.5 A

Resisters questions

Its best to replace both IC's. As far as the resistors, there are location #'s marked on the board where the resistors are mounted. If any look burnt, get the location numbers off the board, and your model # and email me @ I will get you the resistor values.

Bow in tv

Hello trumpold,

The bad new is the resistor is bad. If it is reading 2 ohms its bad because the rated value is .29 ohms and 5% tolerance. I would venture to say that the convergence amplifiers have gone bad. due to excessive current. Since the deflection and convergence boards work together they might both be defective. I would first suggest that you take the TV to a qualified TV repair shop, to perform the repair, but if you what to do this yourself you will need the following items:

1) Schematic of the TV in question ( or

2) Signal Generator or use the on-board Signal Generator (look in schematic for usage.

3) Multimeter (for resistance, and voltage readings)

4) soldering iron, solder, and de-soldering tools (solder wick, and de-soldering pump)

With these items you should be able to determine the components you need to change, and remember follow the instructions in the schematic exactly as to board removal.

Before reinstalling the convergence board after changing out the convergence amps and ALL (I maen ALL) biasing resistors, check for solder bridges and shorts, removing them with the solderwick.

I hope this helps

Thank you,

Need resistor value for RK62 on DP2X board for 57SWX20B

RK62 is a 2.2ohm 1 watt metal oxide resistor hitachi part number 0700054M any 2.2ohm 1 watt resistor will work although it does have to be metal oxide(flame resistant) for safety purposes.

Convergence Board

You just need to change the two convergence IC's part# STK392-110 and look for any burnt/discolored resistors nearby.
