Check and replace damaged component/s at it main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Surf the site with patience. Pull up older posts. Do a search by type in the brand name of your device at its search box.

It will be best to replace the power supply regulator board as card basis.

please check the power supply of your TV,multimeter the export voltage of power supply.if it is defective you can replace it.
if not you need check main boards,and inverter boards
From Wisiny.com can find those parts,power supply,inverter boards and t-con

Why does my 898c always say low voltage on the screen


Hello
Check the input voltage to this device. To work properly without any error, the input voltage at load condition [Switch ON condition] should be more than 11.7VDC. If this voltage drops from this threshold, the unit will display 'Low Voltage"
The fault is nothing but with its input voltage itself. OK.

Emerson mod. ewc 1301 keep blowing fuse


Hello
There must be a direct short in its power regulator section. Normally a shorted switching output transistor at power regulator section will cause this fault. You have to check all the components in the power supply switching retulator section, including rectifier diodes, zener diodes, electrolytic capacitors, small signal switching transistors etc. In fact, you have to check the components in the entire power regulator system. Never put any more fuse into it as an experiment; this will make more components to get damaged. Check the sets' circuit well. OK.

When i turn my tv on it goes for a second than picture is black. If i wait about 15 20 min trying it a couple of times turning it on eventualy it work the tv wil go on and work ok with no futher...


Hi,

This is an indication of out-of-regulation in the power supply section. The very common caused of this fault is the leaky electrolytic capacitor in that section. It will drop the supply from normal voltage and will disable the unit.It needs a little warm-up to make itself stable but the symptom will get worst. Sometimes it has a bulged/dome at the top but not all, it is better that you have a capacitor checker/tester to determine its condition. Your unit will back to normal again if the leaky capacitor is isolated.

If you don't have necessary tools and test instruments, and can't do the job yourself, I would advice you to look for a professional to troubleshoot the problem. Don't attempt to work in the power supply if you don't know the safety precaution of handling it, there some stored electricity enough to hurt you with a little mistake only.

Also check if your unit is under warranty /extended warranty, avail it because the manufacturer of your unit will fix it for free. Don

We have a DLP television and it will not turn on and there is a red light flashing in the bottom right corner


you should check on the power regulator, usually there are several components that cause damage with symptoms like that. I will try to describe some existing components associated with such defects:

1. Elco 100uf/160 or 220uf/160 Volt, may have been damaged / leaking or dried fluid
2. Horizontal output transistor, such as D1554 or similarities
3. Zener Diodes (5Volt) for the IC Program or 12-volt regulator on the main Power (Live Area)

Also check the voltage B +, must be available 115-volt DC, when the TV is turned on. And 5-volt voltage to the IC program should be available even when the TV in stand-by mode

Model txl3676 Too many appliances on one plug. Instead of blowing a fuse in the house the tv Samsung made a poping noise and lost all power. I assume it was a fuse. I have taken the back off the TV but...


NEVER take the back off a CRT or Plasma TV unless you are a certified technician. There are LETHAL voltages present inside the case which can persist for WEEKS after the set is unplugge
It does not sound like "too many appliances" on a plug, although low voltage can cause higher currents and shorten the life of a device.
That popping sound was your power supply failing. This is not something you can replace yourself.
Few televisions have replaceable fuses. They depend on electronic regulation to protect circuits from overvoltages. CRT televisions use large capacitors that loose their filtering ability with age and case errors beyond the range of the protection circuit.
It must be repaired by a technician.

Power out


Start with getting power back into the set supply unit. Could be anything from a fuse to a regulator to a bad flyback transformer....accordianman
