I hope the surge protector is separate from your TV. It has Varistors in it that are supposed to pass overvoltage surges (it can happen without the power going out) then recover to normal. But sometimes they overheat, then they can become a fire hazard. Or the contacts in the sockets can get charred and flakey. Anyway sounds like it is fried, the only easy solution is replace it. A careful tinkerer with a good scrounge box could fix it, if you know anybody like that.

The fault is with its vertical scan output stage circuit. Contact any service technician. This is not a user reparable fault. [Out of Sync: picture]. Gopakumar Gopalan Google

the start of tv set creates enormous static due to it`s initial ampere.it gives static mostly to a/m band radios.it is normal to the tv set while it starts.

1-verify speakers-2-quit the intermed-frequeny sound coil,destroy the internal capacitor and replace for 100 picofarads, adjust.

Does the tv have remote control? If is make sure did got wet somehow.open remote control and check if is dry.

Check for bulged electrolytic capacitors in the power supply inside the tv.

test the main switch for faulty, and replace it .God bless you

If a Mitsubishi (Proton is what is listed here) look on the back for the correct and full model number, no 54 inch sets, 55,60,73 etc.Let me know if power light comes on for a few seconds and then goes off............

Might be some loose solder terminal/s at its horizontal output section. The set should be checked.

There is some short circuited component/s in your TV. It heed service. A skilled work indeed.

open up and check for a dry joint at variable settings on chronos to screen controller if all cables ok ( check for pin damage on connector first sometimes a misalined pin prob

my 42 inch sagem tv is overheating, the red light comes on, then 2 lights come on and then turns off, and light stays on. and only turns off when you disconnect tv. When i turn on the tv after 1 min the light flashes, the tv turns off and the light stays on.

Here a site that you should be able to find user manuals...eserviceinfo.com

Problem experienced was not mentioned and so it seems we are not able to comment. Please post the fault seen with details.

first try to check for the power supply of the TV. the power supply of the TV is located on the place where the main plug of the monitor is connected, check for busted or defective fuse by using a multimeter a defective fuse has no reading on a multimeter. the red line flashes because of a short circuit on the power supply. check for a shorted transistors, diode or maybe a loose connection on the power supply section.may this one help you..

a defective or overloaded power supply or horizontal output stage could create this type of problem

i hope your TV is getting ''off '' by itself when you are trying to turn ''on'' - not when you are watching TV...........then following is the situation ..........IF LED IS BLINKING then---- usually after 4 or 5 yrs EHT ( transformer that supplies voltage to tube ) becomes weak - then TV won't get ON.. means no picture no sound ..but LED blinks - in some TVs along with EHT 1 or 2 components like resistor, transistors, etc will also gets deffective ..........IF LED IS ALSO OFF then on main board in power section area some component is deffective ... MAIN BOARD SHOULD BE CHECKED COMPLETELY........ so solution is TV circuit board has to be checked to find whether only EHT is deffective or other components are also deffective - price of EHT will be between Rs.250 (US$ 5) to Rs.600 ( US$ 12) ........iam from bangalore.....i don't have any idea about EHT component's price & service charge in your area........this problem cannot be solved by user unless user is a technical person having idea about components (resistors, transistors,diodes,...etc..), having multimeter , soldering iron & other tools...so my suggestion call TV service engineer or contact samsung service centre.........

There's a lot of troubles the unit. its probably cold soldered, capacitors needed to replaced, defective power supply and regulator. if you see plenty of moist of capacitor in the surrounding it means you have to replace it, enlarging case or melting tag. some capacitor their feet get rust seem all part were getting worn out. try to soldered the feet of the component maybe there were ring o circle on the lead. There were some cases in physical appearance when you staring on the lead its okay but in the inside where not. i usually was to re-solder stage by stage. then look if improvement on your work. ask me again if nothing happened.
