I turned on my TV last night. it did not have picture or sound. the blue light at corner was on around 10 second,and than blinking. can you tell me what happen to my TV.Thank you so much.

If you have sound knoledge in digital electronics, download the service manual to your tV from net and try to find out.

I have a toshiba 50hm67 tv and with mine the blue light would come on and I would hear sound first and then the picture would finally come on... this happend for about a month.... next the yellow and blue light would come on but the pic still wouldn't come on until it clicked off and on by itself for about 10 min this went on for about a week. All of a sudden last night the red lights by the power light started blinking. No tv now and when the tv shut off it said lamp not working.

Those blinks are fault codes. To know more visit the site linked here. http://electronicshelponline.blogspot.com/

power supply has blown. you need to replace the bad capacitors on it. common problem

For clarification of code/blinks significance you should check at mfg web site .

I just fixed my celera k12b-c11 tv. All you do is hold the f button and the mute button in for 3o seconds, and your tv will unlock itself.

If you hear the high voltage try to come up and set shuts down in 2 secs it could be your FBT also these sets have alot of poor connections chassis should be resolder.

yes... i actually work at verizon the tv is to old for fios because fios is so advanced we run off ot 720 to 1080 depending on areas. what kind of box is it? is it the hd box or stb>

Sony has a code for those blinks indicating the problem area. Count the blonks till the pause then google Sony blink codes for the area to fix.

no kidding? what is the problem so prevelant in this unit? obvious design flaw.
