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?

Re: Can't find the "service only switch"

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.

I have a Hitachi 42 inch rear projection TV. The other day, the color went almost like it looked 3D and then the screen just shut off and the power light on the front just blinks red.

Look for the model number (43fdx01B etc) and from description I suspect maybe the convergence chips----confirm to me actual model number and I can tell you how to proceed.

Hitachi Ultrascan HD remote

Any Hitachi remote made over the last 15 years should work the basic functions of this model--Take a look on Ebay. Did the original get lost or stop working?

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 e-mail

Hitachi model 50UX22B turning off on its own

The TV is in shutdown. The red LED is the shutdown indicator. Check fuse E994. If its open, the TV will need the deflection P.C.B. replaced. Its probably not worth the repair costs. These sets also have had problems with the voltage regulator circuit, requiring replacement of the regulator IC at a more reasonable cost.

Thomson scenium doesn't start when we switch it on.

First, try to unplug and reset. Second, Remove back cover and check for shorted horizontal output transistor with ohmmeter. If shorted replace flyback. Next, carefully disconnect plug connectors from deflection pcb. No need to disconnect h.v. or screen leads. Remove from plastic frame and look at bottom (solder side) for cracks around pins of flyback transformer. Resolder all pins. Last, look for two or three bulging capacitors in power supply on same board and replace. Any of these things can cause a dead set. Good luck, Russmann.

Cp150 capacitor

The "C" stands for "capacitor" and the "P" stands for power. so look on the power/deflection pcb that is on the left as you look at from the rear.

Hitachi 43UWX10B No Picture No Sound

Check the stand-by circuit to the main pcb for the keyboard control. If no voltage present, check the 5v regulator in the main supply. If you are not seeing the LED on your supply up, it's likely you do not have the 5v stand-by.
