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. Surf the site with patience. Pull up older posts.

SOURCE: Tv out of Focus

Well you did start out good, thats cool, now we have to define focus, Is ir blurry around the edges as well as the whole Picture? If it is, it could be the picture tube, A bad solder connection on the tube socket, and yes it could also be the flyback transformer.

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

in jvc av-27020 we called that problem as on timer.your red LED indicator blinking.the reason is your vertical ic is defective if your vertical ic is la7832 replace it with la7840 if there is no la7832.that is most common cause of blinking in jvc 27020

SOURCE: kv24fs120 dead set with two led blinks

Two-blinks of the "Diagnostic STANDBY/TIMER LED" indicates one of two things:

1) Horizontal Output (Q502) in shorted on the A-board.

or

2) IC702 is shorted (CB board)

Two-blinks of the diagnostic red LED is a " B+ Overcurrent" problem.
The red LED will blink 2-times, stay off for 3 seconds, then blink 2-times. The cycle repeats.

The circuit board is quite delicate. One should not attempt repairs (unless one has high quality vacuum desoldering equipment such as a PACE desoldering unit).

Your video card is either blown or needs reseating. Is your pc booting. Check with another monitor. Do you have an add on video card or is it onboard. This is not a monitor problem as a rule put a PC problem.

Is totally dead. First, I received blinking led, but right now, nothing. Si habla espanol, mucho mejor para mi, si no, puedo conitnuar en ingles.


Hi Eduardo,

First of all, thank you for contacting Fixya.com regarding on your TV problem.

I'm assuming here that your TV's model no. is TCP50S2. Most of the blinking LED on Panasonic TV's has a corresponding error code let say the led blinks 5 times(won't turn on), it is a 5 Volts malfunction either on the P board (power supply board) or on A board. Some of the blinking led error code are related to faulty electrolytic capacitor on the power supply board. It will dropped the normal working voltage of the power supply and will disable the unit. Faulty capacitor most of the time has a physical indication of fault like bulged/dome at the top and can be easily identify through visual inspection. Watch the video below for more info.

In your case, you've mentioned that the TV is totally dead set now, this is an indication of fault either on the P board or on A board but most cases I've encountered a faulty P board (power supply). I've suspected that your P board gone to multiple parts malfunction aside from the capacitor.

If you are going to DIY, I would advice you to check the output of the P board using a multimeter to confirm its condition. Once it has a missing voltage, replaced the entire board. Click it HERE for the P board's replacement.

Hope I helped you.
Have a nice day!

Ratings and feedback are highly appreciated!

Kind Regards,

We replaced the V26 dm repair kit and the problem still exists-tv won't turn on . What do you recommend?


Did you also replace the power capacitors on the power board. Usually the DM board and Power board caps together will cause the steady blinking led the DM caps alone only rarely cause the steady blinking led usually its a combination of both boards capoacitors failing.

Many problems could cause the power supply board LED power light indicator to blinks.Capacitors are dying only one problems,but common one.Check carefully for dying capacitors are bulging ups or puffing ups on it tops.If find no capacitors dying and leakages,could be anything on the power supply board is dying or already dead.Must have to know major electronic skills and troubleshooting skills to find which components exactly.Best,just try website like Ebay.com,to a whole refurbuish power suply board for the replacement.

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.
