This is the capicator $1.50. You have to take off the back, sauter off the capicator (you'll see it because it is poking out) and sauter on the new one. I found the fix on this web-site.

The capacitors in the power supply are bad. Take the back off, look at the capacitors, "barrels", if the top is bulging up, they are bad. Caps are around $2 each at radio shack x 6?

I had the same problem with a 52" Samsung LCD. I found 2 electrolytic caps with bulging tops on the power supply board. (see pic). I looked to be the 5v section but I'm not sure. I got replacement at Fry's for $1.90 each. All is well!

SOURCE: red light on power button flashes, but no picture....blank screen

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: 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.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

Hi, We have a 42" hslc10668phz


generally when you get a constant green light all is ok. these different lights indicate different problems within the tv. so the pattern of lights you mention suggests there is a fault of some kind (is there a troubleshooting section in your manual)? either way it needs to be looked at.

Replace the lamp would be the first thing to try. Lamp door switch on this model is notorious for going bad. If you replace lamp and still won't turn on jumper door switch. If you take off back you can see switch board.
