They are very relevant because you might have a high voltage ark from the output transformer or a shorted picture tube,the ark or high voltage leak you might not see but the shorting of the picture tube you will when it does it,being careful remove the back cover and leave the back open,turn the tv on and wait for the moment the shutdown takes place and look at the neck of the picture tube and thru the glass of the tube you might see the moment it shorts out and the set shutsdown,if you see something in the neck of the tube is because the tube is bad,take a look at the conections in the crt board maybe one of them is loose,the arking or leakage from the output transformer is dangerous and it should be observed from a safe distance(10 feet),if you notice something in the output transformer he will need to be replaced,both situations involved high voltage areas and if you are not too familiar with tv service you should get the assistance of a servicer.It is a good idea to resolder the main board if the two possibilties do not show or when the main problem is corrected.Let Us know how it goes or if you need more information.

Why does my Sony 57" Hi-Scan 1080i? 16:9 Projection Television keep turning itself off. I turn it on and after 10 min it shuts itself off I can turn it back on but the longer it is on the quicker it shuts...

Sounds like a heat problem. Check to make sure that if it has a internal fan that it is working, and clean any dust build up, most projection tv's have fans, usually the number of flashes indicate a code that repeats.

No picture, no sound, stand by timer light flashing

Need a little information here...

1. The TV remains on, yet there is no picture and no sound? Or does the TV turn off altogether?
2. How many blinks does the standby light give? Are they continuous? Is it the same each time, or random?
3. Did anything else happen before this, or did it just happen one day?

Answer that and I'll try to help with what I know.

Blank screen

These tvs are known for bad power supply capacitors. Try power cycling the tv several times (8-10) to see if it finally comes up. Four flashes indicates a power supply problem or a deflection problem, usually it is the first. Take the set into a shop if you are not an electronics technician, as these are dangerous areas to work on. Otherwise, use a capacitor checker to test the caps, starting with the main supply caps which are usually 200v. I've found these to be low by 200uf. Also, check the 1000uf and 2200 uf caps. These will be low by 100 - 200uf.

It could be a flyback or deflection problem, but check those caps first.

KV-32V40 32" TV Problem:

Need a little information here...

1. The TV remains on with no picture, but the sound is fine?
2. How many blinks does the standby light give? Are they continuous? Is it the same each time, or random?
3. Did anything else happen before this, or did it just happen one day?

Answer that and I'll try to help with what I know.

This problem is indicative of a problem with one of three (of the same) ICs. Give me a bit more info and I'll give you some links to the solution, or help you myself.

Sonykv-32v40 red ligt blinking black screen and soud good

Take it to a shop... It's a good bet that the jungel Ic, crt driver Ic or something in the HV has failed. Could be also that the crt itself is failing. If that's the case a tech can test it with a B&K and know for certain.
Also, if you want to save a few dollars take it in to them, don't make them come and get it - it just drives the price up for a pu/del charge.
