SOURCE: toshiba 42wt29b. screen keeps turning blue

MMMM Hard call here. The fact that it does try to come on blue maybe an indication that the power supply regulator circuit is good. It could also be a shorted blue tube and when it comes on its overloading the screen drive and the set goes into overload protection shutdown. The real way to see Would be to pull off the blue crt socket as well as the Hi Voltage lead on the crt and see if the set comes on without blue. If it does Your gonna need a pict tube. If it dosent then troubleshooting along the switched power supplys would be neccassary.. BUT I advise you THAT IF YOU HAVE NO EXPERIENCE TROUBLESHOOTING TV SETS PLEASE SEEK A PRO TO ASSIST YOU AS THERES VERY HIGH VOLTAGE INSIDE THESE SETS EVEN IF THEY ARE UNPLUGGED. GOOD LUCK

SOURCE: sound cut-out

Most likely this unit goes into protect mode due to heat detection. Try to see if there is a pattern to when this behavior starts. Does a lower volume level allow the unit to run longer? Perhaps there is a problem internally that is allowing DC voltage to get to the output stage. This will cause excessive heat which can then cause the protection circuit to kick in. This unit may need to see a bench with some test gear to locate the exact problem. If you can, look for any pattern and update this.

I have a 65 inch toshiba tv it work perfect the day before the next day no picture no sound and the power light keep blinking red


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.

When i switch my tv on it has a habit of switching itself off. The red light will still be on and a little green light below it flashes. some days it does it somedays it doesnt. Some times it does it once...


The television is switching itself off to protect itself because there is a problem with it. It may be a bad capacitor, which is usually the case but you have to catch it before it gets any worse. Because then the television will switch itself off and not come back on. The light will just continue to blink and on top of replacing the bad capacitor the entire board the capacitors are attached to might need to be replaced as well as the power supply and main board. Please do not keep turning your television on while it needs repair because it will put itself into a coma and contact a service provider asap.

TV Turns Off Automatically While Watching


Stop trying to turn on the set. You are causing more damage. The hissing sound you are hearing is either a High Voltage Transformer on the SMPS (Switched Mode Power Supply) indicating a short somewhere in the set or some capicitors that have shorted out. Also there can be a CRT that is leaking cooling fluid onto the Main bd or the Power/Deflection bd or both bds. Have a trained Samsung tech troubleshoot the set.

Power indicator blinks; but no picture.


Likely to be the STK convergence chips causing a protection circuit to cut in and switch the TV off when turned on. Do you hear clicking when you switch on?
