Flyback transformer [LOT] short. Replace the same with similar type and number, and replace the horzontal output transistor alongwith it.

Tv does not turn on


If green light flashes more than 8 times, it could be as simple as repairing or replacing the power supply. Unplug the TV ,remove the back. Look for bulged or leaking capacitors on the power supply. Do it yourselfer? only if you have soldering skills, or purchase replacement board. remember, used boards are just as old as your failed board, buy new or rebuilt, Good Luck

My husband's e-machine T2882 began to make jittery noises the light on the front flashes as does the monitor with a ticking sounds then nothing happens. You can't get it to turn on. We've rebooted shut...


If there's a ticking sound, its probably your hard drive giving out. You have to read what comes on the screen for clues but .....................

You could try booting into safe mode (press the F8 key while booting several times) and completing a system restore. (Start - All programes - Accessories - System Tools - System restore) to a date when it last worked.

If you can't get to the safe mode, then, as its 7 years old, its probably time to treat yourself to a new one.

New lamp turns on flashes 7 times


Just a thought...you *might* have a bad ballast in addition to that defective power supply.That flashing could be the ballast trying to ignite the lamp. A lamp is just like an enclosed welder's arc. The ballast generates a high-voltage spark to initially start the lamp, then low voltage with high current keeps it burning. If you look into the lens and see "lightning" flashes but no lamp ignition, that's what's happening. The ballast could've been damaged by the defective supply. Also, try a known-good lamp...just to rule out a defective new one--in the shop, we kept all old working lamps as testers.

Power/standby light flashes 7 times and the tv doesn't turn on


Audio Protect (7 Flash): When DC voltage is detected at the speaker or
woofer outputs, IC3604/pin128 (TV-micro) goes low and IC3604 turns off
the main power (AC relay turns OFF).
Troubleshooting Tips:
1) Main cause of defective will be located on the KD-board
2) Confi rm KD-board is securely seated on the G2-board
3) Replace KD-board
