It certainly sounds like the Red CRT (picture tube) has heater-cathode leakage and is not likely worth repairing, as all 3 tubes usually have to be replaced at the same time for best picture quality.

hello When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for
the picture to appear on-screen. See "IMPORTANT NOTICE ABOUT HOT LAMP R
When the TV has been powered on long enough for the lamp unit to get hot, it may take several minutes for the picture to appear on-screen
in the following situations:
• When the Quick Restart™ feature is set to OFF and you turn the TV off and then on again within a few minutes.
• If the TV is on when a short-term power failure, power surge, or other similar power failure occurs, such that the TV loses and regains
power within a few minutes.
This is a property of DLP TV lamp technology and is NOT a sign of malfunction.
If this occurs, the green LED on the TV front panel will blink (and the red LED will be lit solid) until the TV is finished restarting the lamp
and the normal picture appears. If BOTH green and red LEDs are blinking at a one-second rate, you will need to turn the TV off and then
on again to restart the lamp.
ESTART" on page 8. if this no good check the lamp in side to see if it's not burn't out good luck

Red lamp light stays light


I doubt that it is the optical assy. it sounds more like a chassis problem either on the DM or the FMT board.

check out www.tv-techs.com
if it is a chassis problem it will cost about $250.00 plus shipping one way to fix the chassis

56" sharp 56dr650 rear projection tv


Hi - wanted to let you know that I have the same problem and I contacted Sharp (800) 237-4277. They offered me a prorated exchange. Select #1 prompt for Operations and then they will create a case number if you don't already have one and then send you over to the Disbatch Dept. They are picking up my 56" TV and are selling me a LC52"D65U for under $450 current retail value of the new TV $1900. Give them a call and see if they can work out a deal for you too. The whole transaction will take 7 - 10 days. Good Luck!

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
