Re: Dead KONKA 21 inch TV

Try Check first all the output voltage in the secondary of the chopper transformer if regular voltage acquire. check secondary switching circuit feedback towards the opto isolator and syscon.
Assuming that HOT is OK.

Why I have a thin line across the screen in my TV model Panasonic TC 21. After replacing the vertical IC the horizontal line across the screen reduced to few inches and not as it was earlier. vertica

First, You should to replace by original part, then you should check the voltages on power supply, and check the voltage for vertical IC based on datasheet, also check the voltages on vertical section including yoke and last you should check the ESR capacitors on vertical section.

No Display, no sound- not working, showing dead. But input Power is ok. Picture tube filamment not getting power. model sony KV-2192M3

Check the input fuse first. If it is blown, there will be some short inside the power regulator circuit. Usually Sony sets uses STR regulated power supply. You can see this STR, and Ic, screwed onto a heatsink. Replace it with a same type and number. Before replacing the STR, check the diodes used in that section for damage, mainlu zener diodes. They might get shorted along the blowing of the STR. Check that section throughly before resoldering the new STR.
If any further assistance you needs, get me through Fixya. Ok.

Have a sony tritron wega flat screen tv and it wont turn on, its red light blinks three times, what is the problem and how do i fix it?

Your TVs horizontal output stage is not working. That means, the line output side [LOT and related components], are inoperative. It may be due to some secondary missing voltages from the power supply section of your TV. There may be some open resistor, or short inside the Line Output Transformer [LOT] itself. Anyway that side is not working. Your TVs power supply regulator system has no trouble. It supplies the required voltage to the other sections. That is why you see the LED [Light Emitting Diode], fitted in front panel of your tv blinking for some time and shuts off. As soon as the TV is switched on, the power regulator system inside the tv will supply all the necessary secondary voltages to all sides. If at any section misses the required voltage, the system control Ic will detect it, and will try to rectify that. It is so programmed at the factory. If it can't do it, it will automatically shuts all the supplies from the power regulator system. It is a protection added by sony to all models of their Tvs.
You yourself cannot detect and repair this fault. Get the service of an experienced technician.

My 35 inch tv had a major failure today. while

If red LED light in your TV flashes in series of 6 or 7 blinks TV is repairable - High Voltage IC need to be replaced. If anything else, beside fuse in Power Supply - than forget about it.

Sony 2167 No power on

I have not worked on your particular model. But, I have serviced many TV sets over the years. My answer will ge generic.

Check all the capacitors in the horizontal output stage and power supply areas for high ESR. All the caps that are out of spec must be changed.

The high voltage multiplier & flyback can also cause the fault you are having.

You have to consider that the DC voltages are not the only important spec that has to be met. There are also many power drive signals that work with reactive devices. If there is any defect in the critical areas there will be failures.

Red light blinking

If the tv is a dead set with only as you say the red light blinking, then your tv has a defected power supply or related circuit.if the screen light up with no sound then the tv is having a problem in the IF circuit or also the power either case you will have to call a tech to look on your set to repair it.good luck

Power light blinks

I would start with C869 a 2.2 Uf at 200 Vdc in the power supply. I have replaced a fair share of those in these sets. Of course the first thing to check would be the pico fuse in the power supply regulation circuits F860 a 4 Amp Pico Fuse and if it is blown, you will have to replace Q801 the Regulator IC Str-Z4214 Part # 23906369. If you're not that good at soldering and measuring capacitance and resistance, this would be a job for a more experienced tech.

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.
