Tv turns on but no picture or sound, power light blinking

I have a 27 inch Toshiba about 8 years old, great tv. Model#CE27H15 has seen a lot of on time over the years and one day it finally up and quit. No sound or picture but you can hear the relay click when turned on, the power light keeps blinking but nothing else works. I used to work on tv's for some time on the side of doing electrical work. Thought maybe it is in the power supply a transistor or transformer. Maybe someone can help on this issue!

    the power light blinks constant

  • Chad Solt Jun 23, 2007

    There isn't any picture or sound at all, the picture tube would still be slightly lit black even if it was on another line(input)

    Does anyone know what the part number would be for the voltage regulator, the last person who gave me adive on the VR, it was the wrong part, it didn't even come close to mating the VR. Thank You

Still having problems with this? I'd say you're right, it's definitely something in the power supply. The only sure way to find out exactly what is to start taking a voltmeter to the various connections in the power supply, and see where the power stops.

TV power red light is blinking and no sound or picture

Model number if not the one listed here will be on label on rear of set along with month and year the set was made--


How skilled are you with working on (I presume it is a older direct view with a picture tube) sets?

A lot of the older JVC sets had a common issue---there is a single filter cap (it will look ok) that fails----Tell me model and If you are able I will try to direct you to it.

RCA 27 NO PIC / SOUND - Binking green light

I ouldn't find any good news on the web about this,
so i did a bit of research and discovered that it wouldn't cost me much more than the cost of repair if I went to Best Buy and bought a new HD-TV.
Wow ! The prices have really come down !
Now I'm glad that it malfunctioned !

Tv turns on w/pic then pic dissapears light blinks 4 times

I have the same issue, we've had to change our bulb three times in less than two years. now we have 61" expensive paper weight. Our current bulb is less than 6 months old. The TV is only 2 years old and like i said this is our third bulb.

the blue light blinks 4 times. you get sound. then a few minutes the the picture returns... then it goes out, and the cycle goes on.

A solution to this would be greatly appreciated.

Current value of a jvc 32 inch color tv 8 years old

The street value would be 100-150 dollars. If TV is a cheap model or abused or very used, you should pay less.
Consider a Sony or a Toshiba in tube style since all are cheap now.

Television power led blinking

are you sure that you are checking this correctly?
What is the location number for this regulator?
If its the main regulator, what are you using for ground on your meter? Also, isn't the part number marked on the regulator?

52 inch sony rear projection t.v.

Whining sound most likely is a bad flyback transformer. You are probally looking at a 350-450 bill depending on the repair shop. If your picture was "great" go for it. If the tv has a lot of wear let it go. Nothing the repair shop does to fix your problem will make your picture better than it was before it went out. Somthing to contemplate.
