Picture Blinks for Four Minutes

The TV takes about 30 seconds to a minute to show a picture. It then takes at least another 3 minutes to to I guess "warm up" then it will stop blinking. It did this a year ago and then stopped for a while when we got a new cable box. Now it is worse than before. In the last week after it has "warmed up" it blinks once or twice.

If its a cable box proble shut the cable box off then hold the power button in for about 30 seconds. It will display on the display "reboot" and it will reset the cable box and then upgrade the firmware in the cable box. Check if the tv has somthing like this also. Also try a powercycle. Unplug it over night then try it again. Better to try a few things before you have to carry this big thing to a shop. Tvs arnt very light. Remember the front of the Tv is the heavy part, lay it face down on a blanket and dont slam on the brakes.

Sorry to be the bearer of bad news but your tuner sounds like its intermittant. Only way to fix it is to replace the tuner or send it out for an overhaul.. Now this is onlty if when you say the set blinks the picture stays but turns snowy and wavy or does the set blank off and on like its turning on and off. If thats the case could be a picture tube problem or a HV shutdown because of a vert fault or a driver problem in the Horizontal curcuit.

Very good chance that there is a tuner problem here. If you are handy with a solder gun you could fix a common problem with RCA-GE-and Pan/ TV's. First thing is take the back off carefully and disconnect the rca jack screw. look at the board that the tuner is connected to. You should see 3 solder points. those three are a common problem as the solder cracks and gets a bad connection. however that is going to be the last thing you re solder. You are going to take that bad boy off and work on it. Now you have to take the cover off that tuner part and you will see some cracked solder joints inside of it. Get some fresh solder heat them up and put the case back on it. Now re-attach your tuner to the main board and solder them good. Look around that board for other large grounds that are cracked. put it back together and you should be good to go. NOTES: Learn the proper way to degouse the TV before working on it. I Normally take a screw driver and a ground clip and clamp one end to a ground on the TV and the other to the metal of the screw driver. Push it under the rubber flap of the Tube and when it pops its good to go. Other tools needed 100W iron and a 30w iron. SOme of the joints are old and need super heat to get them to juicy up again. Have fun and good luck. Jim

SOURCE: sony kv32s42 trinitron color tv blinking

sounds like a bad picture tube. Picture and bright settings cranked up for a good pic? Test/rejuv with a crt tester and/or look at the Ik signal on the crt board. A good tube has 3 small pulses during blanking. The crt cathodes are checked with these pulses, pulses too low and the jungle IC will blank the drive. If the picture fades in and out I would check the filament ckt but that doesn't support the "blinks"

SOURCE: Delay to see the picture

Your power supply is going south, I have an old sony with the same problem. The voltage level drops and does not have enough 'kick' to start. It will work better when it is warm. The module will need to be replaced.

Good day.
First, Have your tv 's circuitry be resoldered. this might be a case of loose contacts particularly along the crt circuitry. the longer you operate the unit at this condition, the faster you are counting the possibility of shortening the lifespan of your tube. 9 years is quite a young age for a unit which has an average of 18years.


response is highly appreciated.

Samsung T.V. goes on for 30 seconds then no picture

If this is a flat panel LCD tv, this is a sure sign that the panel itself is bad. I have seen this before. Tv comes on works fine then within 5 minutes goes blank.

Blacks out for 1-30 min. then back on. Standby light blinks 4x

I would suspect the circuit board around the HV transformer area to have a crack circuit print. Also look around in the vertical circuit for interment solder connections. But only do these things if you have some knowledge of TV circuit lay out. If you do not feel confident then call a professional. No sense in hurting yourself or damaging the the set worse.
Hope this helps,

Buzzing and poor recption

I wish I had a solution--My DVD picture and sound is fine, but it takes about 30-40 minutes to get any kind of picture but it is broken--not clear at all - and the sound is all garbled, totally stops for seconds to minutes a a time. It is only a little over a yr old. I finally isconnectexd today and am going back to my cheap-o but dependable tv.

Tv turns on but takes about 20 minutes to show the picture

This is the picture tube. If you check shops you can find one that has a picture tube restorer. If they run just the cleaning process it will buy you some time. This is good some times for up to a year
