Sylvania model ld320ss8a wont power on

Could be the DVD player. Make sure there is not a disk stuck in it.
(This is one reason why you shouldn't buy these kind of units... if one part breaks, it all breaks.)

Damaged component/s at it horizontal scan output stage circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. 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.

Just type this need in google search and you will find plenty of sites providing it free.

Most likely an issue with the power supply. Check the power supply for swollen or leaking capasitors. you can order replacement caps from www.digikey.com

Had same problem Sylvania SRT2232s 32"had to keep powering on and off until it warmed up enough to finally stay on. Problem was the 100/50 & 1/50 filter cap took it to local repair total cost to fix was 74.52 works better than ever
