No picture but have sound

Thats almost always a vertical output issue. I would check the solder on the vertical IC located on the D board . If the solder is good or if resoldering doesnt help then I would try replacing the IC itself.

It appears something is wrong with the green tube.

This set has a history of bad picture tubes but there is an adjustment you can try to see if it will buy you some time to use the set further.

v\:* {behavior:url(#default#VML);} o\:* {behavior:url(#default#VML);} w\:* {behavior:url(#default#VML);} .shape {behavior:url(#default#VML);} Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Here is what you need to do.

1.) You need to remove the entire plastic piece below the front of the screen. You most likely will find 3 screws on either side in back that you have to remove.

2.) The grill will not come out easy, pull from one side and then when it starts to come loose from the other side(there are several plastic pegs that hold it in.) Then from the bottom pull out( most of these sets have square plastic tabs at the top that tuck in.)

3.) With the grill removed locate the inspection plate behind it (it usually has 6 screws.) You will have to tilt the grill to the left and on its side as several cables are connected to it--they are held in place with trash bag like ties that you can release to get some room.

4.) With the inspection plate removed you will see a fairly small (about 3 inch square) BLACK PLASTIC BLOCK WITH SIX CONTROLS-usually they are marked with whiteout so someone can tell if they have been adjusted.

5.) You need to look very close at the block with a flashlight----usually the top three controls are FOCUS--don't touch those.
The lower three are usually marked Screen and if you look very close you will see b, g, r(blue green red)

6.)Usually the GREEN will be in the middle.

7.) Once you locate the GREEN screen control have the set on and turn it down--if the set is shutting down you may have only a few seconds to try to turn it down---usually to the left with the Screen control.

8.) Best way to do this if the set is on is on a video input clip_image001.gif with nothing connected--you turn the Blue screen down until the set stays on and then very slowly turn it up until you see a slightly Blue screen with or without diagonal trace lines----turn it down slowly until the GREEN screen and trace lines just disappear.

Let me know if you get it to work--Like I said if it is shutting down you may have to slowly turn the screen down a few times to get it to stay on.

Standby timer is blanking 8

Hi,

The Standby/Power light of the TV blinks when there is any internal malfunction in the TV. The self-diagnostic function of the TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue.
Few examples are given below; some of the issues may be resolved without the need for service.
1 blink / 2 blinks / 5 blinks: - This indicates that there may be a power-related problem with your set.
3 blinks: - This indicates that there may be a power-related problem with your set. The set will need to be serviced to allow a technician to determine the specific issue that needs to be repaired. If the power light flashes three times in sequence in a Lamp TV, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
4 blinks: - This indicates that there may be a back light or lamp power problem.
6 blinks: - This indicates that there is some kind of audio problem with your set.
7 blinks: - This indicates that there is a temperature problem with your set. Please check to make sure that the air vents on the sides and back of the set are not blocked or clogged and there is adequate ventilation around the television. We recommend that you check and clean the vents periodically to make sure the set receives adequate air flow. If the problem continues, the set will need to be serviced.
8 blinks: - This indicates that there may be a video-related problem with your set. If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.

If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.

Thanks for using Fixya.

How to reapir on tv

Hi malinao,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board for your convenient, it will not require any soldering, obtain the board from your local Sony Service Centers.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

My kp-57/65wv600 flashes SIX TIMES,

First off I would check your lamp to make sure it isn't burnt out. Usually the lamp door is on the backside of the TV. On my 2006 SXRD its on the right side of the TV just behind the buttons. Here is a link to a diagnosis page
