WHY DOESN'T MY TV GO ON?

The main system control memory IC to your TV is faulty. It should be replaced. It is a very small IC, having only 8 solder terminals, and can be located very near to the main system control IC. It will look some what like this, and will begin with a numner 24c**

It should be a main power regulator baord fault. Contact any service technician.

TI calculators have an annoying habit of dimming the screen, especially when the batteries are changed, so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
If this doesn't do it, please reply to this post and we'll go on to the next step.

Hindsight is wonderful---always suggest a extended warranty since it either gets fixed or exchanged.

Most sets come with a one year parts and labor warranty but not all.

If the set is dead let me know brand and model number (on label on back) and I will try to assist you.

This set is getting close to 8 yrs old, chances are its not worth repairing, its been out of warranty for a really long time, look for a new TV

Heat is a huge issue in these TVs, make sure you have adequate space around the tv and that it is fairly well ventilated.
also while changing the bulb, run a vacuum and get all the dust bunnies out of it, those can cause alot of problems with the airflow in the tv.
Lastly, make sure your fans are all running, without a working fan, the bulb will overheat and cause premature failure

If changing the batteries doesn't fix it then call wherever you bought it or whoever made the TV and get it repaired or replaced. Unless you bought it somewhere you shouldn't have, this unit has a one year manufacturer warranty and they will pay to have it repaired or replaced. Good luck.

Lamps have a limited life. They useually last 1000 hours or so. If the TV is on from 07:00 until say 23:00 every day, that equates to 60 days.
There is no such lamp as a "One time replacement lamp" as they do not last for ever.
The average life of a lamp is just about 6 months.
If the picture is cloudy is probably needs the optice cleaning. It is very fiddly and damage can occur easily so get an authorised Hitachi repair service department to clean it for you. It should be carried out in your home and will take less than an hour. If anything gets broken, it is not your problem if they are heavy handed.

Hope that helps.
