I have a sony kp53hs30 big screen. set will not come on and flashes a 6 code. set started out as having audio problems... only being able to here about every other word,then developed squiggley lines on the picture along with a hissing sound coming from the back, and then finally died. could you please help?

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

Try this. The follow was found on tv-forums dot com by Zyntar...
There is a secret service menu to converge the Sony KP53HS30.
Caution: Be careful, there are many settings that can be tampered with. Some may be hard to undo.
Procedure: (use the remote control for these steps unless noted)
1. Turn TV off with System Off (under flap on remote)
2. Press: Display, 5, Volume +, then Power. If successful, service text will appear on the screen.
3. Use 2 & 5 to select the PJE Category.
4. Press 9 to get to fine convergence adjusting.
5. Press 6 several times to get the convergence screen of choice. I like the grid.
6. Use the remote's arrow keys (joystick), move the brackets around until you have found the area to adjust. Press the center of the joystick to change the bracket from white to a color. Use the joystick to adjust the color. Press 3 to change color to adjust. When done, press center of joystick again.
Note: Try to keep the grid even and squared up.
7. Repeat steps 5 and/or 6 for all parts of the screen that need it.
8. Once done, you need to save your settings. Press: Mute, Enter. Then on the TV, press "Flash Focus"
9. Turn off power.
TV is ready to use.

Power Supply board is dead.Replaced the power supply board will solved this problems.Tries Websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for replacement.

on the sony we have to make the convergence alignments on all the modes, only a qualify tech can do that

A 6 flash shutdown indicates low B+, also known as a power supply problem. Not easily fixed or even located by an average consumer. Basically, you have to determine if the part of the power supply that supplies the voltage is bad, or is something loading it down? I know people don't like this answer, but you need a tech to narrow down the problem for you. Sorry!

I don't believe it is stuck in the sleep standby mode, rather it has shutdown with an error. Is there a pattern to the flashing? Does it flash a set number of times?

Hello worksofgrace,

I gave this advice earlier, but since your problems is just about the same, I hope this helps.

This problem is linked to a power supply issue. The SSB is part of the power supply chain and will cause system failure if the board is defective. I have seen to many of these type of modular power supply boards fail. The shutdown circuit is detecting excessive voltage/current, and in the process of turning off the set it may have blown something else. I am begining to suspect a design flaw, which happens from time to time. I would suggest having a qualified TV repair person take a look at the TV and work on it.

Thank you,

The blinking 5 times is an error code meaning that the white balance has a failure. And because you are experiencing a blueish screen then your problem lies in the circuit of the blue picture tube or possibly the blue tube itself is starting to go bad.
