Question about Projection Televisions

1 Answer

I have Hitachi 42pd3000 with its controller unit av3000e, they both switch on fine when they are not connected to each other,however, when they are connected the they come on fine for few seconds or some times for few mins then they start to switch on/off and they keep doing this for ever. it is like the tuner box and the screen are out of synchronization,so the tuner will switch off to the standby and switch back on while the screen is on the way to switch off, then when the screen tries to come on the tuner switch off and so on. any help thanks in advance

Tv won't turn on


Have a shop look at it, there is a power relay that either is causing this or something right around it is, seen this about five times over the last ten years in Hitachi sets. I had one customer who had it connected to a wall switch and from time to time had to unpower it several times but once on it was fine.....

AUDIO PROBLEMS/NO SOUND


Look first to see if sound when a DVD etc connected to a rear input has sound.

Look to see if in audio menu speakers are switched to ON or OFF.

If you are connected with a box, receiver etc via rear audio/video jacks--unplug those units and the set for a while and plug back to let each try to reboot.

What is the AV Net code for a PS3? Will it connect with my Hitachi 60V500A to Input 2 if I have the proper code?


AV Net is for controlling devices with your Hitachi remote. Your PS3 does not use standard IR or RF technologies for it's control, and uses Bluetooth instead.There is a Logitech Harmony adapter that will allow Harmony remotes to control the PS3 however it won't work with AV Net.

Your PS3 should hook up to your TV via Input 2 with no codes needed.

My tv has no volume,i checked every cable connection and it all fine.I know my speakers are fine in the tv everything was fine until a button was pressed on one of the remotes the tv or the direct tv...


Remove all batteries from your remotes. Unplug the unit for several minutes. Plug unit in and use the controls on the set to turn it on and adjust the volume. This will eliminate the remotes. They could have a button stuck. If this does not work you may have a legitimate problem and need a tech.

Red haze


This problem is caused by a failure of the light optics engine, this is a very common problem on these TV's, I have replaced more than 35 of these in the last 3 years
The price of the part is around $500 to $650 not including labor

How do you adjust the fine grain convergence on an hitachi 53hdx01b?


Hello,
Your problem description is not clear.May be you have convergence problem with your unit.
Press flash Focus button on the control panel of the unit.If the flash focus complete one full cycle there is no problem with convergence amp.
Inorder to adjust convergence you need to enter the unit into service menu.

Natura Hitachi 36in TV - Not turning on.........


Check the flyback transformer for cause of the odor . If it is a cap look for a cap that is buldging at the top of it . The flyback is the transformer with the red lead going to the picture tube . You might see it is cracked or a tiny hole in it . Good luck
