How to replace Power Supply in Toshiba 44NHM84 44" TV

My Toshiba 44NHM84 44" TV turns off after about 30-90 minutes and I have to wait about 30 mins for it to recover. But the same issue pops up agin. I have read on here that the power supply is the most usual culprit.

Is it easy to replace? is it just a PCB or are there other parts that need to looked at?

    Thanks Dan for your help with this issue.

    The only indicator light that changes is the power light that starts to blink and then goes to red.

    Is this any indication as to what might be the problem?

    Thanks again

    I googled for this exact same problem.  Found this post.  My shutdowns seem to be much more random, but have the same problem.   Once the damn thing shuts down, I can't get it back up and running.  

    After a 30 minute wait I can get the tv back on for anywhere from 5 minutes to another 2 hours.  There seems to be no pattern or predictability.  Advise is greatly appreciated.

    Even had a tech here and so far all he thinks it might be is the lamp, which makes little sense since to me...

Since this is a DLP type set, there is a lamp and ballast involved. When the set shuts down, are there any indicator lights on the front? If so, check the owner's manual for an explanation of their meaning. Typically, the lamp can cause this or the ballast. If either of those are the problem, usually the lights on the front panel will indicate it.

Keep us posted.

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Sharp tv troubleshooting

There are two main causes for symptoms like this. Usually people replace the TV but it's actually much cheaper to fix.

1. The Power Supply. Just like computes, screens and tvs have a small power supply inside, usually directly connected to the power cable. Sharp can get you a replacement power supply under $100 and you can put it in yourself with a screwdriver or have someone do it easily.

2. Ask an electrician to check out the main capacitors (or if you know how to use a voltage tester, just be sure to unplug the screen and hit the power button a few times first to discharge) If you find a faulty capacitor, they're usually under $10 to replace.

Most likely one of these pieces is getting overheated and shutting off, causing power to fail to the rest of the TV.

Turn tv on watch it for 20 mins. screen shuts off but green power light is still on. turn it off manualy wait a few mins. turn back on watch for anouther 20 mins or so then screen shuts off again

The reasion your set is shutting off is because the power supply is dieding, and you need to replace the electrolytic caps on the power supply, or purchase a new one, go to sand check to see if they have your power supply.

Went to turn the TV on and it will not come on. No sound or picture. There as been no movement or anything done to the TV.

More likely to have power supply failure, the power supply is always running to supply the power to the processor waiting to get th turn on command form the remote control. Look for bad caps in the power supply and check the fuse, Need to verify if you do have the standby 5vdc, you must have this voltage before going any further.

Could be the power supply. You can check the power from supply with multi-tester or voltmeter. If have a service manual, then I suggest testing the ballast as well

Tv turns off after 15 minutes of use

For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.
