Question about Televison & Video

1 Answer

Hitachi 43fdx11b thanks for the support. i've replaced my ic's and found a bad resister (rk46) i belive it was ginko that posted on someone's guest to fix. he said (rk46) was a 1.5 ohm 1 watt resister. i've pulled the resister and the colors are a little smoked, but after comparing it to another resister that had brown,green,gold,gold 1.5 resistance. my resister looks brown,black,gold,gold. is it possible that mine is this 1 ohm resister.

Hello Hitachi,

By me, brown,black,gold gold is one ohm, namely 1 for brown, black for zero and the rest for quality!

SOURCE: 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 (www.servicemanuals.net or www.manualsparadise.com

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,

Shuttle83

Hitachi 61swx10b HDTV - Convergence problems. User 'gdroukas' mentioned in a post that it is probably the convergence amps and a few resistors that have changed value. Can anyone be a bit more specific? ...


Convergence ICs are Big Black ICs and will have the part number on them. STK392-110,
upgrade to 120s or 150s better ICs.
Resistors to replace are RK42 3.3ohms, RK46 1.8 ohms, RK50 2.7ohms,RK54 1.5, RK58 3.9 ohms. RK62 2.2ohms
Mats Electronics has STK ICs 1-800-628-1118 order convergence Kit that comes with resistors.
ACME has the Convergence resistors they must be 1 watt resistors 1-800-575-9833

Let me know if you need any more help Thank You.

I have a 54 inch Hitachi 57G500. The picture is now showing double on the blue spectrum color and auto magic focus is not fixing it.


Most likely this set has bad convergence amp ic's and some open resistors. This can be a very tricky repair. Check:
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
Hopefully this will help. Thanks for using fixya.

Incorrect resistors on DP1X PWB?


Assuming this unit was never worked on and it was actually working properly before the IC's decided to take a vacation I would recommend leaving them alone as there may have been an engineering change after the service manual was printed.

Hitachi 43fdx11b green wave on top left and center


Its likely that you did not find all the resistors that were damaged when the original failure occurred. Now you must re-replace the ICs and locate the other damaged resistors. Check all, including those you just replaced. Use a good ohm meter and be certain that all the resistors are gold band tolerant(5%) and of the exact resistance value and wattage.

Hitachi 43FDX11B television Ghosting


I had the same problem on my Hitachi rear projection TV 53FDX20B made in Mexico. The blue convergence problem. Blue focus had shifted and appeared like a blue ghost image. I followed the step by step intructions from the fixya site. First Replaced the two STK 392-110 ICs and turned on the tv. No change. Then I went looking for the bad resistor. There was one resistor RK50 (2.7 ohm, 1Watt capacity) which is attached not right close to the printed circuit board surface but was well raised up from the board. The bands on the resistor were a little discolored. I replaced that one and turned on the tv. The convergence problem was solved. Thanks for the step by step instrucitons on your site.
