Question about Sanyo DP19648 19 in. LCD TV
Not sure how much you will want to spend on 19" TV.
Power supply/backlight inverter boards (there are at least 2 versions)
As you can see from the pictures, there are fuses and label on the connector indicating the voltages, start with that first.
You only have two boards in this TV, so verify voltages first to narrow down the problem. I did not find any service manual for this TV. Even if you find the service manual, it may not give the diagram of the power supply/inverter board because it is made by another OEM so SANYO cannot give out the diagram.
Please see my basic troubleshooting guide here:

Learn about bad caps: http://en.wikipedia.org/wiki/Capacitor_plague
Capacitors kit: http://lcdalternatives.auctivacommerce.com/Default.aspx he can make you a set of caps.
Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series

I had a similar problem with my 42 in Philips LCD HDTV.
Here was the problem.
My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of
course) and found four bulged capacitors.
Many electronics companies were sold capacitors that failed in 2-5 years
instead of 10-20. The capacitors fail
prematurely due to a lack of preservatives. Unfortunately, they were installed in all
sorts of devices and cause a wide range of failure problems.
Here are some options for you.
1. Have it fixed by a professional
2. Open your TV and find PSB. Check
for faulty caps. If you find some (bulged
or leaking) bad caps replace the entire board.
3. Remove and then replace individual faulty caps. This takes some soldering skill.
Caps are inexpensive and if you can take care of it yourself
it will save you hundreds.
I have a tip/tutorial
on this site that may also help. It
gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. It's
called: Fixing the Philips Turns/shuts off on its own problem.
Hope this helps and Good luck.
