Question about Televison & Video

Open Question

TV will not come on, even though power light is lighted.

TV worked fine last night, turned it off went to bed. Got up this morning, turned it on, the blue power button lit up, you can hear the speakers "activate", and the screen stays black. No matter which button I press on tv, or remote, it does nothing. Except the power button. I have unplugged and waited 10 minutes and plugged it back in and does same thing. Is there a "fuse" or reset button.

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

Good Day, you all;

The front panel light on Hitachi TV does not really tell you much. To see what the TV is doing or better said NOT doing is remove back from the set.

If you are not a technical type person, it would be better to consult an authorized service center, but if you are perform this; 1. Remove back
2. Observe led and notice which once light, there are as many as 9 LED's.

Now that will tell you what area of the TV's circuits are to be concerned about.

Let me know, Good Luck, big IRISH.

If this is similar to the d52w20 then I almost garantee you need to replace a capacitor. You can check to make sure that's what you need by unplugging the tv, taking off the back cover and feeling the top of 3 capacitors. On my d52w20, CP150 (rated at 2200uf 16V) was blown and the top was bulged out. You should also check CP120 and CP114 to see if either are blown. I don't have a clear picture of where it's located, but I have a picture of what you should see after you take off the back cover.

In the middle of the picture you see an aluminum heatsink in the shape of a 'C' with the opening facing away from you. That is where CP150 is located. CP120 and CP114 should be located nearby, but if you can feel a bulge on any of the tops of those 3 capacitors replacing them should fix your problem. Replace the existing capacitors with a higher voltage rating of either 25v or 35v.

"4 capacitors on the power/deflection board. CP110 220uf 200v. CP120 220uf 35 Volts. CP114 220uf 35 volts. CP150 2200 16 volt. also check entire delfection board for cold solder especially around flyback. bad connections here can cause problems like some of the fp fuses blowing and cutting off convergence supply"

Mitsubishi WD-52525 was working fine and now it will not turn on


This is just a shot - but it worked with my Sony (same problem).
Pressed remote power on button AND held Power button on TV on at the same time.

Set clicked 4 or 5 times and then came on....

Other, most have a (VERY small) reset switch on the rear - near where the power cord enters the TV... Use a flashlight and a mirror to locate it on your set....

Power light blinks, but tv won't come on


I have the 52" version of the Viera model. Mine went out last night and started blinking twice over and over again. I suspected overheating so i just went to bed and tried it in the morning with no luck. Then I unplugged it for more than ten minutes and plugged it back in and everything worked fine. I hope this helps.
