    I got mine fixed about a year ago by a local repair guy (Toronto) who came to my house, replaced 2 of the power chips and re-soldered a bunch of the connections and it has been working great ever since. I could track down the guys contact information if anyone is in the area and interested.

My Hitachi 57F710 TV turns off as soon as it turns on?


The model indicated is a DLP which uses a lamp---lamp will not usually cause set right on and then instantly off----takes it 15 seconds or so if lamp has failed.

Also set has led on front that may blink.

If instant it is turned on it goes off----you have a short likely in power supply or elsewhere.

My tv turns on and off. It will stay on for about 3 min and then turn off. What is the problem??


Hi,
If its Sony KDF-50WE655 TV then its weak lamp symptoms like TV turns off and on automatically and work for 3 minutes as you mentioned.
How old is this TV and did you replaced lamp recently?
Replace its lamp that is weak in result and causing TV off and on itself.
Lamp replacement procedure is written in user manual, very easy, click Sony Support to download copy, if required.
Please buy Sony original lamp for TV safety that is available in Sony Accessories Store under following part number for $200
A1606034B... LAMP BLOCK XL-2100U
If model number is different, let me know.
Thanks.

tv turning off automatically
for first unplug the main power cord of the tv for couple of minutes and then reconnect it.also before reconnecting the power cord of the tv again remove all the external device wires connected at its back such as dvd player/vcr etc etc.just connect only tv wire and check out.if still the same problem then its quite possible that the capacitors and ic on the circuit board are getting short in between so the circuit is not getting completed and cutting in between so the tv starts and turns off.in this case the circuit board needs to be checked with a multimeter.the faulty and burned out component part should be detected and then should be replaced with the help of soldering iron.to make it proper.to avoid further damage i suggest you that do not on the tv again and again as it will short some more tiny components and the reparing cost will increase as per that.at present its the normal circuit short problem in the tv get it repaired before using the tv again.

Power turn off after 45 minutes to 1 hour used


Check the "Sleep Timer" settings. If set to 45 minutes then TV would automatically turn itself off 45 minutes from being turned on. The variance in the "on" times is due to the TV turning itself off after not getting a signal from the remote for fifteen minutes.

Good luck,

A component is shorting out, and the TV is auto turning itself off for protection. Usually it is a shorted out horizontal output transistor. Only a tech can fix this.

Sony TV keeps shutting down ever 5 mins


Could be loose connections on the board where the solder is expanding as it heats up causing a loose connection or something in the power supply or horizontal is over heating and your tv is going into shutdown protection . Good luck
