SOURCE: The TV shut off, made a popping sound. The

Power board short and bad capacitor blown, capacitors usually pop because of shorted or open rectifiers and linear devices that warp inside. This happens due to excessive heat exposure from the current draw. Bad diodes and FET's are usually the root cause as to why capacitors bulge then eventually pop. This means the the x-y sustain boards are not getting their supply voltage resulting a no picture....

The red light flashes an error code for a technician to read, the tv is in protection mode to prevent further damage. Get it serviced at your local repair center or take it back if its under warranty.....

Sounds like it could be a power supply problem I would check power supply for bad capacitors. look for bulging on the top of the caps and replace with same values.

check the main power switch of the TV, then also check the control buttons on the front panel of the TV maybe one of the button s on the front panel is press (normally close state), or maybe the buttons is defective (maybe the menu button)

Sylvania lc320slx lcd power light goes one then off


I recently repaired this exact TV that sounds like the exact problem. First you can take the back off and unplug everything from the Inverter board. Then try to power on the TV and if the green light comes on, and stays on, then you know the problem is in the inverter board. My problem was in the inverter and I found Q1500 (N Channel MOSFET) shorted Gate, Drain, and Source together. It's a simple part to replace but a difficult part to find. If you need help finding the part, I can direct you to the place I got mine for $3 and $8 shipping. Just for safe measure I also replaced Q1550 that is the same exact part on that board.

Tv will not turn on


The green blinks are an error code indicating a specific fault, your power supply developed an 'over-voltage' issue and needs to be serviced at your local repair shop.......

First of all you need to find out which CRT leaked and replace it before any other repairs are done. The clear liquid is conductive and has done damage to the CRT board or boards.
