Question about Standard (CRT) Televisions

1 Answer

Help, please! I am looking for possibilities to fix my tv KV36XBR400.

It has no pic - screen is dead. The tube is not energizing, but the sound is OK.
I played mp3 files sourced from dvd player in time when TV screen shut down. Still, I am able to watch TV, play DVDs, etcs, ONLY if I am sending video signal out to other display (projector).
Hope, it is fixable, look like something is prevent the tv tube from been energized.
Please advise what I can do to fix it by myself - it is damn heavy stuff to lift it up/transport.
Sinserelly, Mikhail.

1996 mitsubishi 40" tv has a black screen and

no pic at all usiually means the the heater element in the picture tube it self is burned out. Also there could be a problem with the internal power supply that gives electricity to the heater element. These are all thing the cunsumer cant fix. You either need to trust ONLY a certified Mitsubishi TV repair man, or replace the TV.
I know it's not great news, but if this advice helps, please give me a good rating.

Sony trinitron television , when you turn on it takes awhile for the picture to come up on screen and when it does the screen constantly blinks

Three possibilities
First it sounds like your Tube EHT ( Extra High Tension) power supply is failing.
CRT TVs need a high voltage around 30K for the tube to work. Whcih is generated in the set, if you hear clicking sound like arcking this will confirm it. Unless you are familiar with HV electronics you should not attempt to fix it since it can be dangerous.
Second possibility is the picture tube is failing.
Third possibility is there is some problem with the video circuits, to check this try connecting a VCR or a DVD to see if the picture is OK. If it is, the problem is in the video circuits.

The problem I am having with my samsung tv is it has just recently started to make a hissing sound that I can only describe as the noise of a gas leak ...the pic etc is ok only having problems with sound...

This is a High Tension "Leak" this is a frequent occurance, it is the High Voltage drive to the screen that causes it. really you should have it looked at by a professional serviceman get a firm "Quote" for any fix before you proceed.

Red light blinking

If the tv is a dead set with only as you say the red light blinking, then your tv has a defected power supply or related circuit.if the screen light up with no sound then the tv is having a problem in the IF circuit or also the power either case you will have to call a tech to look on your set to repair it.good luck
