Question about Hitachi 43F300 43" Rear Projection Television

1 Answer

Can't find the "service only switch"

Hitachi model 43FDX01B

I had the back cover off and looked all over the deflection and power PCB, but I cannot find the "service only switch." I need to push and hold it while applying power to reset convergence RAM. Where the heck is it?

Take the front panel off behind the speaker grill and it will be a small button manybe blue or white and that is the button your looking for. it is at the front of the board and you can only press it when the tv is on to go into service mode.

Hi,
    According to the system the problem in your projection is convergence and the solution is to replace the IC STK's.The part Number is CZ01341. Change the IC STK both and your TV work fine again.And for parts please see the link below.

Check for blown fuse EP91. If the fuse is blown, check for a shorted IP01 regulator transistor in the deflection power supply. If that is shorted, change the IP04 photo coupler and leaky D05 a 12 volt zener in the OCP circuit of IP01. If this all looks good, look for an oily fluid on the printed circuit boards under the picture tubes. Good Luck

Hi,I have a problem with my Hitachi TV, The problem is deflection PCB, part # JT23274, model #43fdx20b, How much is cost to repair?


Hi, i'm a technician in florida.
The cost for me to referb a deflection assy is
289.50 plus tax.
i'll give you a nice tip...sometimes the convergence circuit temps to load the power supply...try to fix the convergence circuit first...then see if that fixed it.
convergence ic# stk392-110...try the stk392-120, they are more reliable...my e-mail bhzrdg@yahoo.com

as the problem cannot be the rectified by the user. as it may require authorised service personnel. the problem might be with Tuner,video processing circuits. also mainly with the deflection circuits

Blue wave shadowing


The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
