Toshiba cf36h40 tv runs fine for hours, but will snap loudly and sometimes shut down.

Retrevo has a link to the User's Guide for the CF36H40, http://www.retrevo.com/support/Toshiba-CF36H40-TVs-manual/id/283bh634/t/2/ . In the specifications section of the manual, the weight of the TV is given as 157.4 lbs (71.4 kg). This is on page 33 of the manual.

If you follow the link at Retrevo, you will need to enter a code to download the manual.

I hope this helps.

Bad power supply board !!!

You best bet for getting those would be to purchase a non working unit off of an online site. Ive seen them go for a very low price as opposed to what one would cost new. An alternative would be to call the company directly and see if they could sell some.

1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.
4. The laptop works fine when it runs idle, but shuts down as soon as you start using any memory demanding applications (DVD player, image editing software, video editing software, etc.).

Solution:
If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It's nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.

1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes you have to open the laptop case all the way down.
2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
3. Clean the fan and the heatsink with compressed air.
4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

I decided to use a shop vac to suck the dust out and it worked. I tested it by letting the machine run all night and it worked. It's been a couple of weeks now and I'm glad I did it. I was ready to take the machine apart, now I'm glad I didn't. I'd suggest you use a heavy duty shop vac to clean out the fan and heat sinks first.I agree. Try to fix the problem without taking the laptop apart first but I would recommend using a powerful air compressor instead of a vacuum cleaner.
If your laptop is still under warranty, you can take it to any Toshiba Authorize Service Provider and fix the problem at no charge to you.

“My Toshiba laptop suddenly shuts down by itself without any warning. Sometimes it works fine for hours, sometimes it shuts down in 10-15 minutes.” This complaint we hear from our customers over and over again. About 15-20% of all Toshiba laptops we get for repair, suffer from an overheating problem. Yep, OVERHEATING!
This is one of the most common problems with Toshiba laptops we deal with.
Indications of laptop overheating problem:

1. The keyboard and the bottom of your laptop are very hot when the laptop is working.
2. The CPU fans are working all the time at maximum rotation speed and operate much louder than before.
3. The laptop suddenly shuts down by itself without warning. When it just started, the laptop was shutting down after 1-2 hours and how it shuts down after 5-10 minutes of operation.

Ok This may be due to having a heated CPU/MOTHERBOARD and can cause a fuse to shut down to stop further damage like when a computer detects problems. My solution would be to get an airated space and when it shuts down feel the back of the tv to feel for heat, open windows when turning on or blow a cool hairdryer into the back of it.

the code for your TOSHIBA TV is :
code 0154 , 0156 , 0060 or 1256 , these codes
taken from the "ONE OR ALL" URC 6012W , hope it helps , AJ

The most common cause for what you are seeing is a shorted gun in the picture tube. When 2 elements (heater and cathode) of one of the guns inside the neck of the picture tube touch, that gun goes full on and overloads the flyback (high voltage) transformer. If it is in the blue gun, the screen will go bright blue with light blue "retrace" lines in it. The computer senses the overload and shuts the set off. At 2 years old the tech most likely tried removing the short by arcing between the elements. This works sometimes but the short often comes back a few months later. Another attempt at removing the short could be tried, and it might work this time, but it may or may not work for long. The ony other solution is to replace the picture tube but that would cost much more than the set is worth. A qualified tech will be able to tell you if this is the problem in your set.
