Try a "hard reset" first by unplugging the set for 30 seconds. and if no help, you may have a problem with the SMPS power supply, it might have a bad capacitor or two by now. Worth repair if engine is good compared to a flat panel.

Image outside of bounds of television.


There should be a format button on the remote you can hit. This should cycle thru all the "formats" that the set can do. 16x9, 4x3, wide mode, Full mode, stretched mode, etc.. Let me know if that helps you.. Happy holidays... Jay

I have a T5054 TV and the picture has zoomed in and is way too big, however in the picture settings menu the zoom option is not highlighted in Component mode.


There could be a problem, but verify the settings as listed in the owner's manual as follows:

1 Press the MENU button to display the menu.
Press the ▲ or ▼ button to select Picture, then press the ENTER button.
2 Press the ▲ or ▼ button to select Size, then press the ENTER button.
3 Press the ▲ or ▼ button to select the screen format you want.
Press the ENTER button.
Press the EXIT button to exit.
16:9 : Sets the picture to 16:9 wide mode.
Zoom1 : Magnifies the size of the picture on the screen.
Zoom2 : Expands the Zoom1 format picture.
Wide Fit : Enlarges the aspect ratio of the picture to fit the entire screen.
4:3 : Sets the picture to 4:3 normal mode.
Just Scan : Use this function to see the full image without any cutoff when DTV
or HDMI 720p/1080i signals are input.
Press the P.SIZE button on the remote control to change the picture size.


And realize the restrictions as listed:

• In TV, VIDEO, S-VIDEO, and COMPONENT(480i, 480p) modes, all screen
modes can be selected. (16:9 ➞ Zoom1 ➞ Zoom2 ➞ 4:3)
• In COMPONENT(720p, 1080i) or HDMI(720p, 1080i) mode, 16:9, 4:3 and
Wide Fit can be selected.
• In Zoom1, Zoom2 and Wide Fit modes, you can move the picture on the
screen by pressing the ▲ or ▼ button.
•You can not change the picture size when PIP is set to Double.
•When Double ( , ) mode has been set in PIP, the Picture Size cannot
be set.
•Wide Fit can be used when watching a Digital HD (High Definition) signal.
Wide Fit sets the optimum picture format by expanding it both horizontally and
vertically. For example, you can reset the picture in 4:3 format to 16:9. Wide Fit
does not support all external devices (DVD, VCR etc.).


Keep us posted.

BLOTCHES ON SCREEN


This may not be the problem, but the following service bulletin may be of interest:

Last Update: 1/25/2006
Document Reference/Event ID: E30094243
Model: KDSR50XBR1, KDSR60XBR1
Subject: Picture might have a slight Greenish tint.

SYMPTOMS
Under certain conditions (especially cold/ first power ON), white areas of the picture may take on a slightly greenish tint after power on until internal temperature stabilization is achieved. Typically, this disappears after approximately 10 minutes operating time, however, in certain cases (i.e. colder conditions) the set will continue to fine tune the picture longer that 10 minutes. This is in order to create optimum picture performance under nominal viewing conditions.

This is not a defect but a characteristic of the LCD panels. Be assured that the time it takes to disappear will neither lengthen nor reduce over time.

If the condition improves but reduction in effect is desired, there are customer adjustments that can minimize this condition. Please demonstrate these adjustments with the customer, to determine if these settings are acceptable. (User adjustments are supplied in Solution A)

In cases where no Uniformity improvement is achieved (after 30 minutes power on time) proceed to Solution B; Optical block

Note:
Please be aware that all Optical Blocks exhibit warm-up behavior.
Replacing an Optical Block will not eliminate or significantly reduce the time below 10 minutes.

RESOLUTION

CAUSE:
Internal temperature stabilization needed.

Solution A)

You may reduce this effect by changing some user settings as follows:

(1) Change the Color Temperature setting to Cool - (refer to page 81-82 of the instruction manual). If further reduction is desired proceed to step 2.

(2) Slightly Reduce the Green bias (only available in PRO Picture mode under Advanced video settings), then select white balance Adjustment - (refer to page 81 of the instruction manual). Example:
a. Menu, Video, Picture Mode, Pro Mode
b. Menu, Video, Advance Video, White Balance, G-Bias (Reduce several steps)

Solution B)

Replace Optical block after gaining approval from Sony Tech. line.

Yes my freind it is a convergence problem. There are two stand up IC's standing upright about a 2"X3" square. they start with STK. You should just replace them both if you have any solid state repair experience. If you dont, please stay safe and call in a trained tech to assist you with this repair. Good Luck PS please dont forget to rate this thread
