Sound but no image on Hitachi 42pd5000


Two things need to be checked. The ballast board and the T-con board. Shine a flashlight on the screen with the TV on...If you see a faint picture moving, then the T-Con board is OK. The ballast board for the white backlight is bad. If you don't see a faint picture, then the T-con board is bad.

What cause hitachi flaatscreen tv to black


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel. If so, they can't be replaced. In this case; a panel replacement is the only repair. For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS]. To such sets, the power supply section circuit too should trouble shoot. Contact any service technician. The circuit will differ with models and versions.

Usually there is a warranty period like 30 days.Ask for a replacement if that dont work either there is another problem goin on.Then just ask for your money back,there is sometimes a restocking fee.

My tv shows a picture for about 10 minutes then no more picture but sound remains. what could the problem be? thanks


One of two problems:

1) You have a problem with your power board/inverter. This is most likely the result of busted or bad capacitors on the power board. If you know what you are doing, you can try opening up the TV and taking out the power board and replacing any bad capacitors using a soldering iron. If not, take it to someone you trust.

OR

2) Your LCD backlight panel is going bad. The backlight is the light that shines through the LCD to show your picture. This can be fixed by 1 of 3 ways, you replace the whole LCD panel and backlight (expensive), you can get your hands on a broken LCD of the same size with a working backlight and swap out the backlights (takes time and knowhow), or you can actually repair the backlights themselves (much harder and somewhat dangerous).

The fact that it happens consistently or after 10min implies that it might be an issue of the backlights overheating until they shut off or power board overheating to the point where it can no longer provide enough power for the backlight. Try keeping a fan on at the side or back of your TV and see if it makes a difference. It may or may not make a difference, regardless of the issue.

Hitachi 42pd5200 TV switches between on and off when turned on.


The most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
