Question about Hitachi 65SWX20B 65" Rear Projection Television

1 Answer

I have a hitachi 65SWX20B projection TV. When I power it on, I get no picture, no sound, and on one of the circuit boards, an LED (D967) blinks dimly (1/2 second on, 1/2 second off). A soft click is heard with each on/off transition.

If the board with the blinking LED has larger than average parts on it, it is likely the main power supply and the clicking may be from a relay that is connecting and then, disconnecting the AC. With no video or audio, the main power supply has likely failed. Contact Hitachi service to ask how much the repair or replacement cost of the supply is. Make sure you have all involved model numbers handy; the one from your set with the mfr. date if present and if you can find an assembly number on the power supply itself. it may save you time and errors. These boards are often simply plugged into other assemblies with dissimilar plugs but if you decide to DIY, take some snapshots of the cabling to be on the safe side.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hitachi 51UWX20B no sound, no picture, blinking green LED


The 392-150 is a higher current device then the 110---you can use either--this is normal in the hitachi sets---I usually replace both with 150's---check the led that does not light---should indicate which voltage source is bad---if it is one of the 2 voltages for the convergence ic's(one is a positive and the other a negative voltage) then the convergence Ic's may be bad---look for any discolored resistors around the ic's---one way to tell if it is a convergence ic is to de-solder both ic's and see if the set turns on(the convergence will be out the window) but if it comes on change both and do the alignments with the Hitachi remote. By the way----the led should have a location number printed on the top of the circuit board.

Hitachi 43UWX10B: Power light blinks continuously on and off, no picture


Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

DP23 LED not lit on deflection board no picture on tv


Good Day, Gil;
Your problem is in deflection circuit (115+v) check these: FP05, DP15, Q777, QH01, TH01, T701, etc. BUT suspect C707 1k pfd, 2kv, and check all the pico fuses (brown) 2" to the right of cap. Good Luck, big IRISH.
