Hello Chac c,
The reason that you are getting a 'red light' is because your lamp is burned out. There is a panel on the back of the TV that gives you access to this lamp. You can remove it and check the part# to be sure then replace it. I did a quick search for you just based on the model# which you provided. You can see it here - http://www.nextag.com/serv/main/buyer/OutPDir.jsp?search=samsung+lamp&gg_site=&gg_aid=1295966762
Hope this helps :)

I have seen that symptom many times. Most likely, the little blue capacitor next to the horizontal output transistor has shorted and popped the main B+ fuse. This is very common in those Hitachi projection sets. These parts should be replaced by a tech familiar with Hitachi projection sets.

when both the blue light and red light are blinking it means 1 of 3 things. 1. lamp replacement. This often works everytime for the repair. TIP!!! DO NOT USE ANY OTHER LAMPS OTHER THAN JVC AUTHENTIC LAMPS. ANY OTHERS AND YOU RISK DAMAGING YOUR TV FURTHER. 2. the fans are not working properly or need to be replaced. They need to be cleaned every so often and they will stop working from burn-out if not done so. This repair will cost you less than 100 dollars. 3. The ballasts are defective and need to be replaced. The ballasts themselves run about 150 dollars. I tell you I have fixed this TV more times than I care to count, not to mention the number of lamps I have gone through. The guy at the TV repair place now knows me by name when i come to buy lamps. :(

A lot of these have bad capacitors in the power board. You can see them look puffy or bulged if you disassemble and look. look for caps that look like this
If they are bad, you just need to replace with similar value caps and the issue should be solved. They should be flat on top, not bulged like the picture. If you have a convergence issue too, this can also be fixed on the same board, let me know if you get to soldering..
you will need a set of TORX bits to open up, make sure you pull the ac power first. Look @ the left side when you get inside for the bad caps, you may need to use a mirror to see back behind the U shaped heat sink (there is a big one behind there that goes bad)..
best of luck, keep in touch
