Question about Hitachi 53FDX20B 53" Rear Projection Television

No picture, no sound

I have a 53FDX20B, the remote turns on the little red indicator light but I have no picture and no sound. I pulled the power supply card and both fuses on the card are OK. Any ideas on repair or troubleshooting steps I can take to narrow in on the problem? I have digital and analog multimeters but no scope or high voltage probes

Anonymous Jul 15, 2007

The power button on the front panel does exactly what the remote does. When the red light comes on the set does produce the electric ?click? as it normally did before. Tried the unplugging idea several times with no success.

We turn the power on and there is a clicking and the red light comes on then goes off imediately and you can hear the unit cycling through trying to turn on but it never does. We had to unplug the Television so it would not burn anything up in case there was a short. I need info and detailed instructions on how to fix it myself. I have a 1999 52 inch Hitachi ultravision projector television.

First thing to check, would be that there is no oily liquid or residue around or on the printed circuit boards underneath where the picture tubes are. If there is, one or more of the tubes are leaking out the coolant and the seals will need to be repaired as well as the board, if it is not beyond repair. If that does not work, check out the power supply voltage . Check to see if the horizontal output transistor is shorted, or that the convergence Ic's are not causing the set not to start up. Good Luck

Could be an open internal fuse or power supply failure

MY TV IS ACTING UP IT HAS SOUND BUT NO PICTURE

Sounds like back-light inverter section circuit fault. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Power light but no picture or sound

Hi!
My name is Chris.
I have this Phillips Wide Screen TV that didn't have or come with a remote, so I had to go out and buy a universal remote for it today from a BIG W Store. I'm having some technical difficulties & problems with switching and turning it on, but as I use the universal remote to turn on the TV, I'm having a bit of a slight problem with it turning it on, Ok, Yes, it works and Powers on, but there is nothing showing or giving me the indication that there is no picture or sound showing up on this Wide Screen Phillips TV, But there is a little red & green light at the bottome right hand corner that keeps on flashing red when ever I use the universal remote to switch the power on. Is there a possibility, that i can get some help on here, to help me out with any suggestions, is to why I'm not getting any picture or sound showing up on this TV with this universal remote ? Is there anyway that i can maybe get some help with this to help me out with solving my issue with the Phillips Wide Screen TV ?

Is it a Fuse or the Power Supply

It's not the fuse. Chances could be your PSU

Why does my flat screen panasonic lose picture and sound within a minute of turn on?

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
http://electronicshelponline.blogspot.com/
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

The TV has no picture or sound but the red light on the front comes on?

The red light on the front is part of the system control (computer) in your television it indicates likely your power supply and computer are functioning. There are a multitude of problems that can cause no picture and no sound. Power supply troubles are most likely. The system control will have it's own little power supply which is always on so it can listen to the front panel or your remote. It will continue to operate when the heavy duty power supply might not. This suggests a shop repair would be in order. House calls can't fix something like this unless they are VERY lucky and find something obvious. You will still pay for the house call even if they can't fix it.

Red light flashing...no picture. TV not turning

Probably a failed main power supply. There are at least two supplies; one that keeps the remote function alive continuously and the second that is turned on when the set is ordered to operate. The smaller supply is a low voltage circuit and that is providing your error indication.
