Hello, I have a Toshiba tv - model 42XV503D which has suddenly just switched itself off and no matter what I try it will not turn back on (upluging etc). The TV is around 3 years old. If I press the power...


Hi, Check solder mounts on power switch for dry-joints, (bad solders). If none are found I would recommend replacing the switch. The contacts inside the switch will be burned out but may be loosly connected when in the ON position when you are powering up from the mains socket switch. After initial power-up, (red light, relay click) the television will draw a huge amount of current to start up which the damaged switch will not be able to handle and will open-circuit.

Bypass the switch (Not Recommended unless you are familiar with electronics) You could try this to establish that the switch is the cause

Hope this is of help to you.

I have a hitachi 50 "plasma that was given to me


First do you see a light indicating that the TV has power? There are two power buttons on the TV (the main power and the regular power button). The red standby light will light up when the main power switch is on. This indicator is just to the left of the remote I/R sensor. You can find the main switch on the bottom front of the tv (it is under the tv forward of the stand). Turn on the Main power if it is not on. Then try the power button on the control panel of the TV again.

Does the standby light change color or blink? (Red is standby, orange is power savings (no signal), blue is on.) If the main switch is on and the standby light doesn't come on, the TV has a problem at the power supply. Try unplugging the unit for a bit (at least 30 seconds) and then plugging it back in. This will reset the internal circuitry. If you see a blinking light, then the TV is reporting a self-test failure. I do not know the codes for this model Hitachi Plasma TV.

The manual for the Hitachi P50H401 TV is available from Retrevo: http://www.retrevo.com/support/Hitachi-P50H401-TVs-manual/id/1233ci869/t/2/ . You will need to enter a code to access the pdf.

I'm assuming you don't have one of the special versions that were intended for large audiences that were only controlled by remote (no control keys on the front of the TV). Remotes.com has the original remote or a substitute remote if you need it. See http://www.remotes.com/remotes/servlet/rs?a=gmi&uuid=13104063628240&smodel=P50H401&brand_pn=HITACHI_P50H401 .

I hope this helps.

TV DOES NOT TURN ON STANDBY RED LIGHT STAYS ON


Hi Friend,
Check your TV's remote battries. If they are good, then, power off the TV at the main wall socket and unplug the power cord, leave it for 5 minutes. Now, connect back the main power cord, hold the Power On/Standby button on your TV and power then turn ON main switch on the wall. This should resolve your issue.

Thanks,
Shiva

No power. the t.v. suddenly turn off


Problem sounds like the power supply pcb if the tv is totally dead with no standby light. However, first check that the main plug fuse is not faulty by replacing it ro checking with a multimeter

Won't Turn On....Immediately Switches To Standby


Did you get your tv fixed? It may be the Sub power supply unit. If the main supply went out it would not light the display at all. Yes it is time for th repair shop. Good Luck.
