    there unfortionaly isent a service center anywhere in my area. im looking to fix this myself

  • sashiglory May 19, 2009

    i cant adjust the convergence if i cant navigate the menu though there is a video out on the TV can i roll that into another Monitor and try to pick up on the menu or are you fairly certin teh Convergence board is fried

  • sashiglory May 21, 2009

    alright if its a convergence problem ive located the two convergence chips but it fails to list a model number on the chip its self >_<
    anyway i could get support on finding out what the model number is and where i could possibly find a replacement? also if someone has a second opinion i do have pictures http://smg.photobucket.com/albums/v502/s...

    what is on screen im fairly certin is a message telling me the signal is week but its a scramble not like its just blurry overtop of said message

  • sashiglory May 21, 2009

    nah its not my source, lol kinda offended but i understand the nature of this website. the green boxy thing in the center is part of the TV's internal menu and its also distorted. i'd try to get it onto the Tuner but its very difficult to navigate the source selecter to try to get a channel in for a picture for you... but the Scrambling is above the TV's Menu its got nothing to do with my source

Try to have a multimeter if you need to repair it by yourself, a good soldering iron, and try to get all the voltages which you can read on your multimeter starting with the connector going to your horizontal circuit bard.your power supply board seems to be working but lets do it from the power supply before proceeding anywhere else.it seems working at about 65% as i should say.you also need a good kind of 60/40 soldering lead.try having the main power supply regulator output area re soldered hope this help.thanks for using fixya!.

Excuse me but, a convergence problem is not indicated; as I see that you have no picture and, only static this indicates that you are not receiving a signal have you checked your picture video source i.e. cable box etc. with another TV? If the cablebox cable can deliver a signal to another set we have a tuner problem or, an input to the set has failed...let me know

This is a convergence problem. You should try to adjust it for the best picture resolution and getting all the colors aligned across the screen. That is what convergence is all about.

You should have some instructions in the owners manual about how to converge.

I could not find the manual for your model on the Hitachi web site, so I can't give you specific instructions, but most Hitachi sets have a smart convergance setup that will do a pretty good job - when the convergence system is working properly.

If the convergence board is defective you will need to replace it. You can get it done by a shop for around $300 to $400. You can buy them on line and do it yourself for about $120. You can sometimes buy a used or refurbished convergence board on the internet, or find a used/junked chassis that uses the same board, etc.

Thanks
Kevin

I have a 50vs810 dlp. The blue and red lights flash in sequence when I turn it on.When they stop flashing the red light for the lamp is on. The yv has no volume and no picture. Is it just the bulb or does...


More than likely, it is the bulb. My hitachi 50v715 would come on(light up and show picture) 3 to 30 sec's with out the lamp indictor even lighting up. Put a new bulb in and works great. So I would try a new bulb. Look in your manual for the bulb number. Buy an original hitachi bulb they last a little longer.

I have the lamp,the tv is still not coming on. Is there something that has to be reset?


Yes. You will have to reset the lamp hours. It should be in your owners manual.
Copy and paste this link in your address bar if you don't have the manual:
50VS810


http://tv.manualsonline.com/manuals/mfg/hitachi/hitachi_projection_television_product_list.html



I have heard that this may work on your tv

1. Switch power ON, and press the TIMER button on the remote control transmitter, or the RESET button on the control panel, for approximately three seconds. The 'LAMP xxxx hr' message will appear on the lamp timer on the bottom of the screen.
2. Press the MENU button on the remote control transmitter, or the RESET button on the control panel, while the lamp timer is displayed. The 'LAMP xxxx [] -> 0 [|] CANCEL' message will then appear.
3. Press the [<|] and select 0, and wait until the timer display is cleared.

It could be that the "White Uniformity" needs to be adjusted which would probably require an authorized service technican to perform. Otherwise, the problem may lay within the light engine itself, also requiring a tech.
