This is a true case of a circuit that develops voltage to trigger the circuit but stabilises after some time when the voltage develops to the threshold that is necessary for the circuit.
Please have these tips and look into the power and main sections of the circuit to find the faulty section

Keep losing signal


You have a weak signal. There are many possible reasons for this, such as:

The aerial has moved or there is a poor connection.

You are tuned to the wrong transmitter.

THE TV PICTURE KEEPS GOING BLANK THEN COMES BACK ON ALL BY ITSELF. THERE IS A GREEN LIGHT FLASHING, NO RED LIGHT.


This is symptom of weak lamp in TV.
How old is this TV and did you replaced lamp recently?
If not, replace lamp in TV to fix this issue.
Lamp light does not lit solid if lamp is not broken or dead.
Lamp replacement procedure is easy and would written in user manual.
Thanks.

The screen shows ''Weak Signal'' and no picture, even though audio is coming through from both the Cable DVR box and Blue-Ray player. The cable box connects to the TV with an HMI cable - all five TV inputs...


Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.

I hope this works for you.

We keep losing sound and picture on our TV


If you haven't replaced the lamp, it is almost certainly time to change it. A weak lamp will cause the TV to play for a short time. As the old weak lamp heats up, it draws more current, and the reflector in the lamp, having become cloudy over time, converts the light into more heat rather than reflected it out into the set. Eventually the lamp draws too much current and the set turns it off, going into a restart cycle. Buy an original Sony lamp, as the aftermarket replacement lamps are known trouble makers. Be sure to rate this solution. Thanks!

Won't keep digital signal


If you're connected to a digital cable box, I would try using the external component connections and bypass the TV's tuner. If all you have is straight cable coming into the house, it could be the cable signal itself or a defective tuner in the TV assuming all the menu settings are correct in the TV.

Projection TV turns off for a few seconds


Good Day, boattech1;
To my understanding the Model 53UDX10B is a rear projection, that uses no fans. I think maybe your LAMP may be getting weak.
Good Luck, big IRISH.

Sony KV-35S66 Audio ok but no Video


Is your picture somewhat weak ? This could be a problem with the picture tube . One thing you can try is to turn the screen control up just alittle at a time to see if the picture comes in . Once it does turn off and back on to see it it comes back on again . It might take 10 to 20 seconds but if it does your picture tube is weak . The control is on the flyback transformer it is the bottom control . Or it may be on the crt board on the picture tube . One thing to check once the picture comes is the video input . If you go to this mode and see faint white lines might want to try to turn the control down a little more to see if you can get them out and the picture stays on , if not thats how going to have to watch it . These picture tubes are expensive $500.00 to 700.00 depending on which one you have . One possible other thing if you tell me the picture was a great picture almost like brand new check the horizontal section for a loose connection as this will cause this problem . Don't get shocked and be carefull , Good luck

No sound on my 8year old panasonic tv.


It worked fine yesterday. Sound on all channels. Sometimes the picture goes black on channel 6. We can get it back by going up one channel, then back to 6. it is due to cable signal ie weak. now there is no sound this is due to sound section 1 loose connect in sound section 2 speaker 3 problem in sound section some part must have failed.

Sony tv picture keeps flashing


You likely have bad solder connections around the tuner area. This model has a history of problems in that area or the tuner itself.
