Re: won't turn on.....

Pincushion Problem, there is a diode on some chassis that goes bad, sounds like you may not know a whole lot about these, I would suggest calling a service tech out to repair.

You had at first either a power supply or pincussion circuit problem.

Going to likely be a shop repair unless you can find a schematic and know what to look for.

A good idea would be with set unplugged take a look inside for anything popped or even burnt.

In the power area look for any bad caps.

Cant get the power to turn on,worked fine last night, it got unplugged, this morning plugged in, won't turn on and the power button just flashse

Flashing is either an error code or the set trying to boot up--some of the Mitsubishi sets if power removed will blink for a minute and then stop--then the set can be turned on.

a model number?

Hitachi 55VS69 screen goes black and there is no volume and it will not turn off unless unplugged.

The key here is you have to unplug it---it means the problem is related to the microprocessor which may become confused because of an issue elsewhere in the set---no real easy answer except it may be expensive to locate and fix.

I have a jvc hd52z585. while watching tv it turned off and the lamp light and the power light are blinking at the same time. i have unplugged the tv for a couple of hours. when i plugged it back in it does...

very easy.
there is 1 thumb screw behind left speaker grill.unscrew it to remove the grill.the lamp is behind that.after changing the lamp,go in to CUST.MENU,scroll down to reset lamp timer. Best price for lamp is Inspect the lamp for internal glass particles for 100% verification of being bad. Also at the root of the glass stem in the middle look for bubbling of the glass. This is another sign of a bad lamp.

Black horizontal lines appear after tv is on for 30 minutes


I had the same problem with our VS-55705 Mitsubishi. It seemed to me that this was a problem of heat.

I unplugged the TV and then took the cover off of the back of the it. I then used canned air to blow off the collection of dust from the components. Then I vacuumed as close to everything as I could without touching any of the components. I then used glass cleaner to clean up the surface of the three bulbs.

I plugged in the TV and it has worked perfect ever since. I haven't put the rear cover back on it yet. That could have been all that I needed to do to fix it. I'm too busy enjoying a nice picture to try putting it back on. Cleaning the bulbs really helped the quality of the picture.

Good Luck!

Power light flashing/ no picture

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.
