Question about Hitachi 53FDX20B 53" Rear Projection Television

1 Answer

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

    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

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 ?

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.

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.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Tv will not turn on when tried on either tv or with remote green light flashes 3or 4 times then turns into red flashing light no picture or sound at all.Have tried changing batteries in the remote and fuse...


Hi.The signal lights red means the primary power of your tv is good and the signal lights green indicate the second power.If the green lights is flashing it means that they have shorted parts in the crt board.Maybe the problem is in the power section of the crt.Need for troubleshoot or repair the crt board.

53FDX20B NO PICTURE AND SOUND


It powers up but no picture? In my experience with Hitachi TV's this has been an issue with the convergence IC's failing. You will need to have a technician replace those if needed.

Sony Trinitron Color TV KV-35V65 - No Picture, red light stand/by timer flashing


A reset won't fix this. The standby light should be blinking a repeated count with a 3 second pause inbetween. Post that count here. That will indicate the circuit/condition that is preventing the set from turning on.

Thanks,
Dan

There are lights on the board about 8 you should look at which comes on and which stay on this by hitachi standards tells you what is wrong. Most of the time its convergence amps bad.
