Power up Problem

Can you guide me in the right direction, I have Hitachi TV that turns on automatically after a power failure in the home. Also I am now experiencing an intermittent problem which I believe is associated with the first problem which is that the when I go to turn on the TV the red power indicator light turns on but there is no picture or sound.

Re: Power up Problem

I think this is your problem
The convergence board needed to be "rebuilt" (lots of cracked solder) The ICs were shot as were several resistors.
this is how to fix it.

I have a 61" hitachi projection tv it would turn

I had a similar problem with my 42 in Philips LCD HDTV.

Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.

Here are some options for you.

1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.

3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.

This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.

Hope this helps and if it does please rate it accordingly. Good luck.

Hi I think my Hitachi C29-F500DR TV has a fault. At first I thought someone had inadvertantly set the timer but the power indicator is not blinking 10 seconds on, 1 second off. It is blinking 3 shorts ,...

Blinking lights indicated any component failure in the TV .

You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..
If its within warranty Please give to the company.....
If you would like to attempt a DIY, you will need a service manual to guide you. You can find one here:

Good luck..

I have a Hitachi 50EX8K projection TV that will not turn on. When you hit the power button you can hear a "click" but nothing happens. I have some electrical knowledge and could use some help pointing me...

if this is projection tv that clicking sound it could be the ballast tryin to turn on a burned out lamp or the ballast could not be sending the right amount of voltage for ignition, you can check the ballast if its liking oil or if you see something burned in the board.

The signal from the STU to the Hitachi box is going in the wrong direction.
Is the adaptor that you have switchable? If so, flick the switch in the

one that is. Then set the STU output to RGB.

Hitachi 51F510 with NO POWER

Something is preventing the power supply from operating:
Possible causes in order of likelihood:
1) Convergence amps failed overloading the supply (See if you can disconnect them)
2) High Voltage circuit has died. (Right on schedule since your TV is 10 years old)
3) One of the CRTs has shorted
4) The power supply itself has died (Is there a lot of dust covering it?)
See if you can isolate the failure by working down the list.
Hope Ya Fix it!
