Why do you make this comment this is clearly a 34 inch direct view tv CRT!
The number of blinks on a sony is a clue to what might be wrong..

You probably just need a new lamp. If your tv is that old, im sure you do. I just got a new one from Projector Lamp Services (relampit.com) it works great... Only took me a few mins to install it too. I missed my TV!!!

My Tv started with flashing red/orange colors. Then later the screen turned red/orange and the TV shut off. When I attempt to turn it on again, the screen stayes red for a few minutes then shuts off.


The problem based on the model number is in or around the red picture tube---the bright red screen causes the set to draw too much current and the shutdown circuit detects this and turns set off--self protection.

Each picture tube (3) has a IC chip on the board connected to it--shorted chip or bad picture tube.

Shop repair in most cases.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

That is either the tube or a short circuit video driver semiconductor.
If it is intermittant, I would go for tube and prepair to purchase a replacement TV.

Sony trinitron television , when you turn on it takes awhile for the picture to come up on screen and when it does the screen constantly blinks


Three possibilities
First it sounds like your Tube EHT ( Extra High Tension) power supply is failing.
CRT TVs need a high voltage around 30K for the tube to work. Whcih is generated in the set, if you hear clicking sound like arcking this will confirm it. Unless you are familiar with HV electronics you should not attempt to fix it since it can be dangerous.
Second possibility is the picture tube is failing.
Third possibility is there is some problem with the video circuits, to check this try connecting a VCR or a DVD to see if the picture is OK. If it is, the problem is in the video circuits.

Sony rear projection screen is red then tv shuts off


Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.

Picture is geen and does not stay


Lots of trouble with bad picture tubes on that model! Remove the front grill and very gently tap on the neck of the center picture tube near the socket with the back of your screw driver. If the picture flashes back to normal that means the the tube has an internal short. You may hear a snapping noise while tapping and the set may shut off. If the tube is not sensetive to tapping it it possible you have some other type of failure.
