SOURCE: my hitachi ld328700 lcd tv picture has gone faulty

ALL LCD/Plasma televisions have adjustment for convergence, RGB drive, color saturation and a virtual host of other parameters than can be adjusted through the "technician's service menu".
Unfortunately, you are not supplied with the information to access that menu and you're limited to a "user's menu" which allows you to only adjust some of the basics, like volume, tone, color, tint and several more.

Methods of access vary from manufacturer to manufacturer. And the main reason that a consumer isn't given access to these menus is simply because they can totally screw up a set with just the push of a button, requiring hours to correct by a qualified technician.

Of course, most all of them have a factory default to recover most of the settings, but there's still a lot of finite settings that would have to be adjusted to get your TV looking right again.

Depending on the LCD manufacturer, it may be adjustable for your specific set, or you could have a problem with the LCD digital or driver modules. Even the LCD display itself could be failing.

Best bet is to call a QAUALIFIED technician and have it checked out. If you don't have an extended service plan from where you purchased the set, or if it's out of manufacturer's warranty, some of the repairs could be quite expensive. enough so that it may be worth looking into buying a replacement set.

It would help a lot to know the model number, it sounds like a convergence problem but I need to know the age and model number (both are on the back of the set.)

SOURCE: Hi my name is Anthony

Oh yes it is possible. There are called "add-on sales" within marketing. The kit will be nearly $200-$300 for the accessories needed to watch your 3d tv.


This is why it is SO important to ask the BIG questions before a purchase.



Thank you and best of luck!

Sony TV losing focus


Your TV most likely a convergence failure. ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

0dcec37.jpg
Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

When watching dvd having showing or fade background


yes it can be down to signal degradation especially via scart lead, make sure you use a decent scart if you buy an expensive one you can tell the difference. Run a cable from your sky digibox direct to your tv to see if the picture improves.
