I have to play with the on/off button on the remote for quite some time in order for the TV to actually turn on. Other than that it just clicks on but the image never comes on screen no image nor sound and I counted to red LED blinking light to blink approximately 7 times. The TV over seems to work fine once it actually turns on but the mission is to actually get to turn on in the first place :( PLEASE PLEASE any advice will help...Thanks in advance!
Seven
blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit
goes immediately into safety shutdown. Check power supply regulation and horizontal
circuits.
You must have through knowledge in electronics to proceed. This is a very skilled wor. You must have all measuring instruments, and ability to follow its schematic diagram.
Thank for a solution! But Wow is that so? what a bummer, would you know any links that would guide me? or is this something im better of getting an actual professional to handle?
Surely,
There is a link, that will do help you to know about what to do how this problem can be solved. All details are described there. But, Fixya had prevented me providing that link to anybody, by a notice send to me yesterday. You just ask them by clicking 'contact' option by Fixya site, and give me permission to send that link name to you. Without their permission, I can't.

The blinking is an indication that the set detected a problem. The code usually indicates a bad regulator circuit. If yu can solder, you can probably fix this your self. Please let me know if you wish to attempt the repair. If not, expect a parts cost in the $25-$40 range plus the local labor rate for the repair.

Hello,For model KV-40XBR800,
Pls check following area.
Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.
And NOTE: 6 blinks also can be Low B+ protection.
Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314
to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.
Good Luck

In cannot remember if this model of set uses on the CRT drive board a drive IC for the CRT colour channels, or if it uses descrete transistors. I have had component failure on this board that causes your description. The failure in your case would be with the red channel drive. Most of the time I had the semiconductors fail, and some of the support components.
Most of the time, a failure on this board is caused by some intermittant internal arching inside of the CRT. If this happens, the CRT is starting go defective.
Another cause of this fault is that the CRT is starting to go internaly shorted between the control grid and screen grid. As it heats up, the shorting becomes lower in resistance, and thus causes the pricture to go brighter until the protection turns it off. This would be with the red electron-gun.
With any failure with the CRT, the set is not worth to fix even if you can find a CRT for it.
