My sony projection tv flashes red then turns itself off, the red indicator red flashes 8 times

Hi,
3 times red standby light flashing indicates that lamp cover (first thing that you removed from tv to replace lamp) is not fixed properly on tv, make sure lamp cover is attached correctly with tv to solve this issue.
3 times blinking is not problem of fan or anything else, it is related to lamp cover that engages safety micro switch inside to turn On tv.
Thanks.

Shorted Green Picture Tube. No Longer Available.

yes u will have to get a expert in but here is a guide to help your tv is going into protect mode if the screen is flashing green with white lines in it its likely that the green tube is faulty this is very expensive & u my want to purchase something else.

Re-insering the flyback wire is usually very easy. Push in and give a slght turn and check to see if grabbed. It sounds as if there is more issues than flyback wire. TV should turn on without one crt connected

I have the same model TV and have had that same problem (*8 flashes) The FLYBACK TRANSFORMER on the D circut board is the most likely cause and will need replaced) the part is around $70.00 USD!
Please rate my response
THANK YOU!

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.

what model of Sony is it? On many of the Sony projectors, a 3 flash error code indicates the lamp is not properly seated/installed or the lamp door is not closed properly

ITS PROBABLY THE RED PICTURE TUB (CRT). IT LOOKS EASY TO INSTALL, BUT YOU NEED TO MAKE ADJUSTMENTS TO THE SCREEN ONCE IT IS INSTALLED. THE PART IS $3OO. TRY TO FIND SOMEONE TO INSTALL IT FOR $150 OR LESS. HERE IS A WEBSITE TO HELP YOU MAKE ADJUSTMENT IN THE FUTURE ON YOU OWN.

I hate to be the bearer of bad news, but you have a shorted red picture tube.It is not at all uncommon on sony rear projection. The gun shorts and the set identifies the problem and goes into shutdown. Usually there are diagonal lines in the picture before it shuts down. this is an unfortunate problem because this set delivers a great picture. The dealer cost of the tube is around $200. When the repair is complete your're probably looking at $400-$600. The only problem is that the green tube and the blue tube also have chance of having the same problem. It'a tough call . But from my experience , I have replaced the green tube and had the blue tube goe within a year. Scrivitron
