Its probably going into protective shutdown ue to an over voltage condition in one of the operating circuits. My guess would be one of the regulator transistors or a leaky diode

I have a 60 inch older big screen. I turned it on and the entire screen is orange


Hello
Your TV has no blue colour emisson. Red+Green = Yellow, Orange and so on. There is so many causes are there for this fault. As you say that your TV is an old one, it may be a transistorsed circuit board inside. Sometimes 2 or 3 Ics also will be there. You haven't given its model number to us. Without that we can't refer to your complaint with schematic diagram. You just give Fixya, its model number and other details and repost your complaint.

I have a magavox big screen


Hello cce357,

This can be any number of things, here is a possible listing:

1) No High Voltage (check the IHVT or the trippler)

2) CRT filament transformer winding open (check the windings that supply voltage to the CRT filaments)

3) Video / CRT socket boards bad (highly unlikely but check anyway)

4) High Voltage power supply malfunctioning (related to problem #1)

This listing is a good starting point. I would suggest that you purchase a schematic to aid in testing the voltages mentioned in the 4 steps above. If you have a background in electronics then do the above, if not please ask a qualified TV technician to perform these steps.

Thank you,

I hope this helps,
