Question about Hitachi 57F500 57" Rear Projection HDTV-Ready Television

1 Answer

Another IR Sensor problem (I think)

Like the other gentleman, my TV last night started to only respond sporaticly to both the TV's own remote and the Sat remote. It hasn't quit all together but it is definitely on it's last gasp. Is this a user replacable item or is it time to shell out some cash for a repairman?

If you get to the point where you can not use the remote anymore you will need the help of a repairmen to replace the remote receiver but before He does he needs to check if the receiver is receiving the necessary voltage to operate.

Vizio tv remote not responding
possibly bad batteries in the transmitter. could also be a blocked IR receiver at the TV(do you have something in front of the IR receiver in the TV?) last resort could be either IR receiver PCB or the MAIN PCB.

My tv [vizio vf550m] won't respond to a remote.
Vizio is famous for having main board issues. If you have replaced the IR board the only two other items it could be is a broken wire from the IR to main or the main board has an issue. Nothing else can stop the remote from working provided the remote is working properly.

My verizon fios remote control stop to control the 65" cinema series toshiba tv.the remote seems to be ok.The oryginal tv remote doesnt control it also.I think that there is something wron with the tv...
Yes, most likely the sensor is at fault - more precisely it's connections to the motherboard are iffy. You must take the back cover off the tv and reseat them. While you are there check their soldering points - with age they tend to melt and get loose.

Tv remote quit working
The remote put out IR (INFRARED) signal that human eyes cannot see, you need to use your digital camera to see it, just point the remote at the camera's lens, you should see flashing light on your camera screen when any remote buttons is pushed.
You may have problem with the IR receiver in your TV, but find out first if the remote is putting out the signals

worst case will be the main logic board.

Ok...so the remote works...now what
If the problem is the IR sensor, then the TV will turn on and work using the buttons on TV, but wont react to remote.

If instead the TV does not turn on all all , then the TV is on protection because of an internal fault , and must be tested and fixed by a technician.

Replacing IR sensor is not complicate, but t is not an user level operation.
The IR sensor is usually located on the front bottom side of the TV, therefore to replace it you need to remove the main board completely, and many other parts.
Additionally on many models the sensor is soldered to the digital board.

If the TV goes in standby, then it is in protection mode.

Pioneer SD-582HD5 - screen went black, no sound, Poor remote feed
The blue tube might be leaking coolant in the high voltage area, that is the cause of the POP. This repair might not be a DIY because of the lethal high voltage surrounding the CRTs tubes.
The slow response from the remote could be because the coolant has affected the main board where the IR signal are going to the remote sensor.
Let me know if you require further assistance.

My TV won't respond to the remote control
If the remote is working but the TV will not respond, it means that the little IR receiver in the TV has stopped working. This is most likely because the receiver has burned out, but it could also have come loose. This is a very easy thing to correct, but the set should be serviced by a qualified tech.
