Mitsubishi Toshiba Samsung DLP TV Bulb Won Turn On DIY Easy DLP Ballast...

Lamp light blinking yellow means lamp door not installed.
Lamp light solid red and TV shut off is lamp error (did not light.)

Your model is the DP-15 chassis which is a CRT projection so you do not have a lamp like the DLP models do. You have three CRTs Red, Blue and Green instead of a single lamp.

if this is a DLP it seems your lamp burned out and needs replaced , if so search ebay with model # for replacement, you can purchase a buld or lamp assembly

hey there it sounds like the problem is coming from your ballast board, the ballast board is the power source to the lamp. with time this part starts to wear out and get weak your old lamp is already burning out there for it does not need that much voltage to turn on but the new lamp has not been worn out or used there for it needs the ballast to be working at 100%

hope this solution helps

Replace the lamp. Look in your manual and find the number for your lamp. Do a search on line, buy the original hitachi replacement. They last longer. Hope this is helpful

Sounds like the DLP lamp failed. You can decipher the Hitachi flashing red light. That should help to be sure.
The DLP lamp replacement is fairly straightforward and can be done with minimal tools

Check your lamp.

Good Day;
Try this:

Symptom: All Front LED indicators are flashing in sequence: Power-->Temp-->Lamp-->Power......continuously
Cause: Replace Lamp . This symptom may happen all the time or it may be intermittent. It is normal if it occurrs from time to time, See OG under TV Front Indicators explanation notes.
Good Luck, big IRISH.
