Hello

Check the settings on your external devices,check the settings on the devices you are having a problem with. For example, if your Blu-Ray player is outputting to 1080p but your television supports a resolution of only 720p, this could cause the audio and the video to slip out of sync.

Try different inputs. If problems persist with external devices, plug them into different ports. The problem may be a bad input rather than a bad TV. Replace cables to make sure that isn't the problem.

Check the settings menu. If the image on your Hitachi TV looks too dark or too washed out, adjust the picture settings in the television's main menu. Sometimes the factory settings on a Hitachi TV aren't in line with the needs of the user

If this does not solve the problem,Press Menu Button, then in sequence 4, 7, 2 and 5.You are now in the Service Menu

Goto Options and press Factory Reset, it will only take a couple of seconds

Press Escape, Standby and Unplug from Mains Leave for 5 mins and turn all on again

If the problem persists, 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. They can be found online.

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.

NOTE; If your tv is still under warranty,do not open the tv as this may void warranty.Best option will be to send the tv back to the dealer for replacement.

Hi pardeep76.

I had a similar problem with my 42 in Philips LCD HDTV. I may have the solution to your problem.


Here was MY 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 to consider.


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. 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 will, at the very least, give you a general idea of the process. 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.


Hope this helps.

If you have any questions for me, please comment on this page. I will be happy to assist you to the best of my ability. Thanks for using Fixya.

This happened to me with my first Hitachi 55" plasma. It ended up being the panel itself, which was very expensive to fix. Thankfully mine was under warranty and I was able to get a replacement TV.
