This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

not true about the 200 hour thing, and the pic qualith can be a couple of things, if you have a cable box, it can be caused by a week signal, or a loose connection, if the cable is just going from the wall to the tv, you may want to reprogram the chanels

Problem with the Toshiba 50H13 50 in. Rear Projection Television. Green tint


The tubes have aged and the colour balance between the tubes has shifted. You will need to redo it using a black/white test image: first the black (the cutoff point), then the white (the gain) on each tube - always start with the green colour. This is done on the final video amplifier of each tube by adjusting the corresponding semiadjustable resistors.

The screen is a grainy and most of the time its almost as if there are is a delay in the picture its as if there are two of everything. but the picture is fine if it is a slow moving sceen.


Hi,
It's a convergence issue. Go into the main TV menu under video settings and look for convergence. If it has an auto convergnce select that and wait a minute the TV will adjust itself and give you a clear picture. If the TV does not have an auto convergence and just regular convergence than select this. It will give you a grid pattern on your TV and you have to move the curser (using TV remote) and adjust each "point" so that each line is perfectly white. If you notice red or blue anywhere on that "line" then you have to adjust using the up, down, left and right arrow keys to "line up the red and blue lines with the nearest white line. It taked time and patience to do, but when completed, all lines on the grid pattern should be pure white and you will have a great looking picture. You have to do this will all TV inputs (Video1, Video2 and so on) the reason Zoom looks good, is because you never used that screen as much and so the lenses didn't have a chance to get out of synch. RPTV's are made of the three lenses (red, Blue and Green) and as you watch TV, these lenses slowly get out of alignment. So you should do a convergence about twice a year to make sure nothing is out of whack.
You can pay somebody to do it, but may cost you like 100.00 dollar or do it yourself, it is very easy just tedious and time consuming. If you have the auto convergence than your golden because this is the easiest way to "reset" the TV.
. Good luck and if you still have the owners manual

I have a Hitachi 57" projection TV Model 57F510.


You may well have either poor contact on the tube base of the colour that is missing or a poor contact in the tube itself. The latter is not repairable.

I have sony 50E200A,there is problem with colour combination/mixing....green colour is too bright.please tell me how to resolve this problem.thanks


You need to calibrate the colors

The first step in calibrating your television lies in paying attention to your surroundings. Sit in the same spot you'd normally sit in to watch your TV. Then, make sure the lighting is at the same level you'll be using to watch movies: setting your TV to overcompensate for a brightly-lit room may give you distorted results. Watching in complete darkness may cause undue eyestrain, but a dim, diffuse light behind or to the side of your LCD TV is best. Just make sure to avoid any glare or reflection on the screen.

Next, be sure your display has "warmed up" for at least a half hour before attempting any calibration; this is to ensure that all the components of the display are at normal operating temperature and best approximate normal viewing conditions. You can take this time to familiarize yourself with the various display controls on your particular TV--get the manual out if you have to. The better you know which controls are available on your LCD TV, the better your end results will be. Though different manufacturers give different names to the controls, these are the levels you'll be adjusting:

  1. Black Level, normally found on the Brightness control
  2. White Level, usually called Contrast or Picture
  3. Sharpness, or sometimes Detail
  4. Color Saturation, usually labeled Color, or maybe Chroma
  5. Color Tint, also known as Hue

Beyond these basic settings, many modern TVs come packed with so-called "picture enhancements" which in reality do nothing but spoil an otherwise accurate, lifelike picture. Take a moment to dig through your TVs menus and disable any of these "features." What you're looking for is anything labeled edge enhancement or detail enhancement, flesh tone or color "correction," etc. This is a broad generalization, but basically anything not listed in the five controls above can be safely turned off. Another thing to check for is often called a "Picture Mode," or something similar: in reviews, we often find best results from a Movie or Cinema mode, which usually gives the most accurate picture with the least "enhancement." A Normal mode is a safe bet when this isn't available, but definitely avoid anything called Vivid, Dynamic, or Sports mode.Sports mode may make the grass look nice and green, but unless you're watching The Masters, it's probably not that green in real life; Sports mode is just ruining the color.

On a similar note, have a look at the options available for your LCD TV's backlight settings. Like many of the settings, the backlight is probably set to its highest brightness, which is probably too bright for comfortable extended viewing, and shortens the lifespan of your LCD TV as well. Drop this setting down at least to it's "normal" value, or even try out the Low Power or Power Saver option if it's available (in dimly lit rooms).Finally, a word about Color Temperature. Without getting into the rather complicated science behind it all, Color Temperature basically refers to the peak wavelength of a light source, which affects the color tint given to images which should be "pure" white. Suffice it to say that while most video is produced to what's called a "6500K Standard," (6500 degrees Kelvin), not every TV comes out of the box set to display that standard properly. In fact, factory settings are very rarely are set close to 6500K.

Sony LCD TV


Your blue LCD panel has gasped it's final breathe. Unfortunately, this is not something that can be repaired at a component level in the field. Your TV requires the Optical Block Assembly to be replaced in order to restore it to it's former glory. HOWEVER, due to the part cost, labor fees, and age of this model... you should spend this money on a new TV and put the balance of the unspent money back in to your pocket... this repair would be too costly to pursue. :(

Picture has double images around the edges of the viewing area.


Firstly check for correct colour registration at centre of screen. Look for coloured halo around white edges in centre area of picture. Use static convergence adjustment if necessary to correct centre of screen. Then follows an involved process of interactive adjustments to attempt correction of errors at the screen extremities. If these are out of adjustment range this is indicitive of a convergence drive fault requiring professional intervention.
I hope this information is helpful!

Hello Paul. I have this same monitor, but rebranded, Access the service menu with the remote control:

With user’s RC
1. Power TV On
2. Press Menu button and call up User OSD Menu
3. Select Sound-> Balance
4. When Balance value is “0”,Enter 0->5->3 ->2 in sequence.
Note: If necessary, re-do number keys.
5. Factory OSD appears.
6. Press the standby button then AC turn off and restart the TV, which can exit factory

The colour on my TV is a reddish colour. Have tried the colour adjustment. Skin colours in particular.


simple. easy. you have 3 screen adjustments. red green blue. turn color all the way down. you should then get just a black and white picture, but in your case, it will still be reddish. behind the speaker grill is an access panel for screen adjustment. remove speaker grill. remove access panel. you will see a block assembly roughly 6 inches square with 6 knobs on it. 3 are for screen, 3 are for focus. adjust until you have a black and white picture. then go into menu and turn your color back up. enjoy!

50V715 HITACHI -GREENISH TINT -


Solution for the Hitachi 50V715. I contacted Hitachi and they told me there is a problem with the color engine with this and other Hitachi models. They will replace the part for free, but first I need to take it to a repair shop to verify the problem and I have to pay labor. Not too bad considering the cost of the engine.
