No power after reassembly

I disassembled the TV to move it. After I reassembled it, I have no power. Any idea where to look? Do you have a schematic?

    That safety switch would be the same as a reset? Once it is pushed a click is heard but the unit still does not come on.

Won't power on...


Unplug the TV for a minute then plug it in while observing the power light. If the light flashes three times then the standby power supply is OK.

If the standby power supply is OK, a diagnostic code can be read from the green power light by counting the flashes. Press the power button once (this sets the diagnostic code). Press and hold the INPUT and MENU buttons on the fron panel for 5 seconds then release. The green light flash a two digit code (x flashes, followed by a pause, then y flashes). If it flashes a 2-2 code then a short circuit has been detected in the switched power supply. It would normally flash a 1-2 code for "no problem detected".

If a 2-2 code is read, check for blown pico fuses on the POWER circuit board. If the FA904 or FA905 fuses are blown then most likely at least one of the two convergence driver ICs are bad. It seems like this is the most common failure. I replaced these fuses and ICs in my TV. The parts cost me $50, but it required extensive disassembly, PC board desoldering & resoldering, and reassembly. If you can resolder circuits on a PC board then you can probably fix it yourself, otherwise call a repair person.

HITACHI 65XWX20B - How to disassemble the cabinet?


The 65XWX20B comes apart in 2 pieces - there is a top half and a bottom half.

- The bottom half houses all of the electronics, projection lenses, etc. It is very heavy and should be moved with care.

- The top half is basically just the screen.

I have moved this Television multiple times, even up and down from a 3rd floor apartment!

- First remove the screws holding the top and the bottom, the important ones are on the sides of the TV.

- This is important, I suggest 3 people do this part: Slowly lift the top away from the bottom half of the TV, but -not- very far. There is small wiring harness that that attaches the top of the TV to the bottom to a circuit board. This must be unplugged by one person while the other 2 hold the top half of the TV slightly above the bottom half. Note carefully where this plugs in so that you can reassemble easily.

- Once this is disconnected the TV is much easier to move, although still quite heavy and bulky. Do not turn the TV on its side - keep it upright while moving.

Reverse this process to put it back together.

Once you have done it once it is quite easy.

Good luck.

I have a samsung LCD tv but the i cant get the touch buttons on the tv to work


All I can tell you to do that might help is to unplug the set from it's power source for 5 minutes, then reconnect it and try. Also, look to make sure one button is not stuck in the engaged position. I've done the Samsung warranty work for several years on those sets and only recall needing parts for this problem once. It was front control pcb and required major disassembly and reassembly. Hope that helps fixya.
