Can't adjust picture?

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

most likely the inverter board is faulty, I think this model has two of them, look on ebay for cheap replacement.

If your TV has a 'Menu' button on its front panel, you can enter its menu using it, and come towards picture adjustment window, and can change the intensity of color. If there is no such button on its front panel, you must have its remote control to do this.

I too would like to know the solution to this question...we are having the identical problem and Sony doesn't seem to know how to fix it. Although, the picture from the DVD player is perfect, the pictures for cable & video games are terrible. Very frustrating!

after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then 1 of the indication is ...'' grrrrrr '' like noise comes ---no picture , no sound - (in case if picture & audio comes also it won't stay for much time) that noise is from EHT .......so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching TV --- this adjustment is very important ) ----------iam from bangalore (09986222774, [email protected]) ----- here EHT's price will be around Rs 250 ( US $ 6 ) & for my customers (in bangalore) i will take another Rs 500 (US $ 11) as sevice charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact TV service engineer ------- because they are highly experienced & can fix this component very easily. ------------ [[ sometimes along with EHT another component called transistor ( big in size - situated close to EHT - it will have 3pins - its size will be 1inch X 1/2 inch X 1/2 cm --approximately ---- black in colour ----- fixed to aluminium metal ) --- will also gets deffective --- so this component also should be checked ]]

after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then 1 of the indication is ....it takes few mins for picture to appear...& in some TVs it will come on & goes off (your case)........so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching TV ) ----------iam from bangalore (09986222774, [email protected]) ----- here EHT's price will be around US $ 10 & for my customers (in bangalore) i will take another US $ 12 as sevice charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact TV service engineer or sony service centre ------- because they are highly experienced & can fix this component very easily.....

after 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then 1 of the indication is ....picture becomes dull (less brightness & less contrast --- that noise is from EHT )........so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching monitor --- this adjustment is very important ) ----------iam from bangalore (09986222774, [email protected]) ----- here EHT's price will be around Rs 250 ( US $ 6 ) & for my customers (in bangalore) i will take another Rs 500 (US $ 11) as sevice charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact monitor service engineer ------- because they are highly experienced & can fix this component very easily.....

Recalibrate the colors. Flaking is sometimes caused by more ink/toner than can be fused to the media. There's a limit for the total amount of ink/toner. Yours may be set too high.
You'll need a copy of the Printer's User's Guide (also Downloadable from Xerox.com)

Controlling Color Density

When colors look faded, adjust the toner color density to extend the life of the components.

Print and use the Color Reference Page 1 In the printer's front panel, scroll to Calibrate Colors,

press Menu and print the Color Reference Page. 2 Compare the Color Reference Page to the Color Density

Samples on page 39. Make a note of the value (-10 to +10) for each color that most closely matches the samples.

3 Adjust the density for each color: Enter the value noted in Step 2 in the Calibrate Colors menu, under Adjust Each Color.

? Decrease color density: Press . ? Increase color density: Press --->.

4 Reprint the Color Reference Page; check your adjustments
