Power on for a few seconds then turn off

Tv is going into x-ray protection mode. Check power supply voltage, make sure it's not too high. 160v dc across main cap, do not use chassis ground, use cap ground. If too high, something is open. If too low, something is shorted in power supply. Check voltage regulator ic.

Switch off it self,with error massege X RAY

The power supply regulator section of your JVC tv has got damaged. It outputs more voltage than normal to that is to be. There is so many reasons for that, including faulty capacitors and faulty regulators. Loose or bad solderings in the power supply section also may cause this type of fault. To retify it, just open your TV, and resolder all the suspected solder points in the power supply regulator section, by applying a little more soder. In most cases this will solve the problem. If not replace the power swithcing regulator device.

I have a jvc av 36980, wont turn on, replaced capacitor c926, still nothing, fuse is good

Hi, I have same TV with same problem. I replaced capacitor with 1000uF 50v and it worked. I also saw another posting that replaced the SMPS (switch mode power supply) STRF6626 regulator. Radio Shack does not carry it though. I had to order one from an electronics store.

Good Luck....Kim

JVC AV-27020 TV Blinking LED, Static Electricity on tube but no sound and image

Sounds like a bad main regulator IC.. Try putting a 100 watt light bulb across the main AC fuse, turn on the set and see if it will stay on longer. If it does, replace the main regulator iC. If it does not, then it could be almost anything in the sweep section of the set, and or in the regulation circuit of the power supply. Look for slightly swollen capacitors in the set. good Luck please do not forget to rate this thread.

Red lines, Red screen, tried previous fixes

I would look for an open resistor in the red drive circuit on the CRT board. Check all the components in the red circuit and replace any which are not within tolerance. The resistor could be from a 1 ohm to 10 ohm depending on the model. If you find no bad parts then check for cracked solder connections on the board and resolder. If this does not work you will need a scope to look at the signal going to the red drive transistor and make sure that it is correct. Anything beyond this will require a repair shop. Remember TV safety. Good luck.
