SOURCE: Panasonic switching to standby mode on its own

Is this a recognised symptom? yes the problem in power supply. it is due to switching oscillator& switcing output circuit probabaly capacitor & transistor. as set is very old so after power supply is ok check for horizontal output also. can it be fixed? yes it is common & not major problem

SOURCE: CRT TV picture keeps getting horizontal line & loud cracking nois

the horizontal section is near collapse, the lines indicate a sort or leak. Soon, the set will go black. Shut off as repair will be cheaper now! Needs professional repair as High voltage section is dangerous.. Unplug to be safe!

Sanyo DP26649 screen blacks out and sound becomes loud static


Most likely you will need to get a diagnoses performed on the set. Your problem could be with either the main board or power supply board. The million dollar question is do you repair or replace? With parts and labor to repair this set, you could come out cheaper replacing it.

Tv picking up channels except its all static, colorless, and loud static noise..


If the set was purchased in the USA it has the USA format which is NTSC--unless the signal is NTSC picture will be in black and white and no sound.

If the signal format there is PAL OR SECAM you will need a converter that takes that and outputs NTSC for the set to work properly there.

My sega genesis has a clear picture but static sound can someone help?


Try an older TV set. I am not joking. It might very well be the case that newer TV sets/high-end TV systems can't handle the signals of the older video game consoles. Because the newr tv;s don't have the signal transfer inside of them to make the old consoles work so you could use the genesis av cables to hook up to a digital tv instead of the rf switch.

Problem with RCA TV Model 27F634T


You almost certainly have a bad picture tube. The green screen was from one of the elements inside shorting out. The static sound you're hearing is the high voltage arcing out through the end of the picture tube to other parts inside the set. It's more economical to buy a new TV than to repair this one.

Sorry to have such good news, but this is one of the ways a picture tube can go bad, and it happens quite often.

Suddenly no sound & no picture overnight: is my TV dead?


If you have static siugnal, sure TV is not dead.

Check the aerial cable, ensure it is well plugged in and getting signal.

If you are using a receiver box, check cables to TV and receiver (freeview, sat, cable etc.), try setting channels on receiver again, if it does not work but you get static, then either the cables or receiver are defective.

Test the TV on standalone , connecting it to an external antenna.
Tune again the channels, and save the preset.
If still no signal then the antenna socket on the TV may be defective.

Try using the TV with a DVD.

If you can watch DVDs, and TV is not keeping channels preset, and you tried all the above, at this point htere may be a fault in the tuner card inside tv.

Call the phone number listed on tv user manual to get support, and eventually repair it.
