Tv won't power up. Keep clicking with red timer light flashing off and on with every click. What could be problem? Fixable or is TV toast?

I Get a similar problem with my Philips TV, which I believe is a relay playing up. I find pulling the power and leaving it ten minutes usually discharged the capacitor holding the relay open and when I plug it in again, all is well. Had the issue for 3 years, it always works for me

No picture or sound. standby light on front panel

The light is blinking a repeating error code. Try to determine the number of blinks before a slight pause as that will be an error code. Then respond to this same post and I will assist you with diagnosing what may be causing the set not to power up.

Replacement of Projection Lamp but no picture of volume now

Pull the lamp out and with a flashlight look at back of the compartment. There should be a cutoff contact switch at the bottom where the lamp pushes it inward when connected. If you dont see this, it is possible you may have inadvertently pushed to hard when inserting the lamp and that switch has to be replaced. It is part of the projection engine/unit and unfortunately that will be expensive if that is the issue. Good Luck

Pincushion Picture on a big TV screen!!!

The set has 3 IC's(one for each color)strictly dedicated for the aligment of each color,if one them does not align is because is going bad or is already bad becuase picture can not be adjusted,the IC's can be identify because they are mounted on a heat sink and have the markings STK--- ---,they are all the same and need to be replaced with an exact replacement.If you are familiar with tv service you can replace them,sometimes the new ones need to be aligned from the service menu,you will need the service manual,soldering and unsoldering will be involved,If you are not too familiar be safe and seek the assistance of a servicer.

Needs new speakers

Check the speakers with a meter (like checking a fuse--the ones in this set are fairly standard and will have ohms and wattage marked on them.Rather unlikely both would fail and if they test good you may want to see they did not get switched to OFF in main menu.There is a reset but try these suggestions first.

How to go in service mode for tv sony kp-46wt500.i did change the stk ic,the convergence is good in the midle but bad on the side

Did you replace the pico fuses on the G board there are two and usually one will blow when the old ICs fail and just replaceing the two ICs on the D board will usually not fix the issue untill the two pico fuses are checked and the blown one is replaced.

Sony TV KP-46WT500

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com Common Problem #1) Convergence has gone outProjection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem. Common Symptoms include....
  • 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.
  • TV shuts off after powering on. The power light will blink. TV may also make a chirping noise.
Here are some pics of convergence problems. 7859b01.jpge87380c.jpg 69189a5.pngSOLUTION #1What you will need to do is convergence. You can get a repair kit from TvRepairKits.com . It includes replacement parts,step by step instructions, support, etc.Common Problem #2) CRT Fluid is CloudyProjection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. Picture of a set that needs the fluid changed.578ba6c.jpg TV set after fluid change65af323.jpg 69189a5.pngSOLUTIONWhat you will need to do is replace the coolant and clean the crt. You can get a repair kit from TvRepairKits.com . It includes replacement coolant,step by step instructions, support, etc.
