Question about Hitachi 46F500 46" Rear Projection HDTV-Ready Television

1 Answer

Hitachi 46F500 46 in. is still bad

After replaced 2 pcs STK394-160E, it still looks 3D. then I found RK42 bunt out, I replaced with 3.3 ohm, it looks better, but green lines are still off a little.
also I found RK47 has 1 ohm on board, (RK47 is good out side the board) and same value RK55 and RK63 showing 147 ohm on board..any ideas?
thank for help or please email me a schematic to
any helps will be appreciated.

If you found the burnt resisters after you replaced the ic you probably burnt the ic out again,

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.

I need the resistor values for RK42, RK46, RK50, RK54, RK58, RK62 when using stk392-120 chips in Hitachi 53UWX10BA.

If it is 53uwx10B:

RK42 2.2 OHM 1 WATT
RK46 1.5 OHM 1 WATT
RK50 2.2 OHM 1 WATT
RK54 1.5 OHM 1 WATT
RK58 2.7 OHM 1 WATT
RK62 1.8 OHM 1 WATT

Double check the numbers on the STK chips as most of these sets use STK-392-110 OR 392-150 CHIPS-----ONLY A FEW OTHER MODELS(MOST 43 INCH USE THE 120 CHIP.)

I do this here for free so if this helps you take just a minute and give me a vote here.
