Question about RCA HD56W66 56" HDTV

1 Answer

My tv won't turn on.

The small green light will come on the front for a few seconds and then turn off without the actual tv ever coming on. The dog peed all over the speaker cover area, but the tv worked for quite some time after that, then one day it just wouldn't come on. It's plugged into a surge protector so I doubt power is an issue. As the wife won't let me get rid of the dog...hopefully someone has a solution that won't bankrupt me!! Thanks for your help!!

    I'm having the same problem. I didn't have a dog pee on my tv, but the same thing is happening. I plug it in, the tv turns on for about 3 seconds and then turns back off and won't turn back on.

You probably have bad connections on the flyback transformer. With the back off of the set, on the left side, you wlii see a transformer with a big red wire coming out of it, The connections under that transformer are bad. Be sure the set is unplugged when doing this!

TV won't turn on


It sounds that, the memory IC to your TV has damaged. This IC can be located very near to main system control IC. A very small one, with 8 solder terminals. Even though it is very small, function of it while the TV works is great. The work is a semi-skilled one, and you must have some knowledge in electronics to proceed.

1 have a 6 year-old Mitsubishi model WS-48511 series 1080 rear projection TV that now won't turn on. A few days ago we shut the TV off, and now when i plug it in the blinking green power light...


This is called the blinking green light of death-----only one of two things can cause this problem.

First: remove front speaker grill (IT PULLS OFF) AND remove inspection plate behind it; look for the two bundles of wires coming down and to the right from the front keyboard of the set.

Unplug both plugs you find (different and marked so you cannot mix them up-----the idea is to take the front keyboard out of circuit-----set will still function with remote as receiver is behind front screen)

Try (after 70 seconds) to turn on with remote

If it comes on---defective reset button on front keyboard----use set only with remote or remove and remove actual reset switch---it is located behind and part of frame for screen----entire front screen would have to be removed to get at it.

Second: if disconnection of the front keyboard does not help, the DM unit is bad.

As you look from back of set it is large metal box at extreme left side.

The blinking light is the unit trying to "Boot" up-----these have a problem where caps and a few other parts in that unit fail-----kits on the net are available----Mitsubishi no longer sells or services these units but PTS Electronics does repair them.


Let me know if you have questions and try disconnection of the front keyboard FIRST.

65" mitsubishi rear projection tv won't turn


IF model number posted is correct and green power light comes on for a few seconds and then goes off:
On front of set press and hold both the Menu and Input (device) buttons at the same time for at least five seconds and release both buttons.

Power light will then blink a two digit error code like 2 blinks, 2 blinks, a pause and repeat it several times.

Let me know what error code is found and I will tell you what it means.

THE TV WILL NOT POWER UP


It depends on a lot of other things, but you could try these steps . . .(assuming its a TFT flat screen)

Has the mains fuse blown ? try a different mains cable.
If it works from a power supply/mains transformer (a small box attached to the mains supply cable), check that box - they usually have a small green light on them to show they are getting power. These are easily replaced if that part is faulty.
Has the power cable come detached from the rear of the TV ?
Does a power light appear on the actual TV front (usually blue or green), and then go red (or off) after a few seconds. In that case the screen has a more hard to fix problem inside :(

The green light comes on then turns to yellow.


if you look at the capacitors on the boards you will find several of them that are domed or blown, these are the most likely cause of the problem. you can find replacements for any capacitor online at electronics supply stores, like radio shack but don't try them they don't supply enough different types. you can also find examples of blown capacitors by doing a search for "blown capacitor image" on any web search. unsoldering these bad caps and replacing them with identical values like 220uf (microfarradys) and say 25 v(volts). these caps have a + side and a - side the caps are marked and so is the board. hope this helps.
