Question about Sylvania Televison & Video
Soundsl like ABL circuit problem. The service work to this kind of fault, will be somewhat skilled. Best is to contact any service technician. Check and replace damaged component/s at its horizontal scan output section circuit. Check the LOT (Line Output Transformer) too for damage. Replace the horizontal scan output transistor. Check the input voltage to LOT. If the voltage is absent check the feeder resistor; if any. If you wish to get some details; check the site linked here. Pull up older posts.

Hey Wilt: We had the same problem, for the same model of Toshiba TV. Had it repaired yesterday. Turns out the problem was the power supply (P.C.B). The total cost was $192.66 Canadian funds (taxes and labour all in). Our model was 6 years old, buts its playing like a brand new unit now. Hope this helped ...... Good luck

This problem is either the TV's software or how the mainboard is distributing power so instead of just unplugging the TV, try a power drain:
1. Unplug the product's power cable so the device is not grounded to the house. 2. Press and HOLD the product's own power button for 1 minute to drain the capacitors. 3. Plug the product back into a wall outlet and try to turn it on.
Note: This procedure works with battery operated devices as well so remove the batteries and hold down it's power/on-off button. Electricity can remain in capacitors and on circuit boards enough to prevent normal functionality. By clearing the residue electricity, your product will have a fresh start and many times this will resolve a buggy or non-responsive device that appears to be dead.
Since hardware either works or it doesn't, your issue is either software or power related since you can get it to work so hopefully the power drain will indicate further.

Sounds like they enabled some test mode of the TV. Can you activate the menu using the remote control and see if you can navigate to disable that? How about if you just unplug it from the wall for 60 seconds and plug back in and maybe it will reset.

SOURCE: tv goes on fine, sound good and pic green light receptor on tv starts blinking and we lose pic sound still good. When we tap the light on tv pic comes on fine for a while then same thing happens again
This television is having problem with intermittent tuner reception.The tuner is the signal processor for the television. The video section is intermittent. This could be a simple matter of cold solder joints that can occur over time due to heat expansion and contraction.This causes the metal in solder to expand and then when the television cools down, the metal that is expanded cannot contract.The solder joints then becomes intermittent. All televisions suffer from this problem.Since you are able to still able to receive the video signal, there appears to be no component damage. You will need to take this television in to a service center and have them rework the solder on all the areas around the tuner section of the television and any other areas that may be susceptible to the problem due to overheating.You can call Magnavox customer support at this telephone number 1-800-705-2000 and ask them for the location of a service center in your area. Or take it in to a local repair center and have them test and service the television for you. You can also try taking it to a school where they are teaching electronic repair and ask them if they will work on the television for you.They will usually do the work for a cost of parts and a small labor charge. Call them first to make sure they will help you and tell you how you can get the television serviced This may not be the only problem you are having with the television. That is why you need to have it tested first. I hope this information help you with your problem.
