H out transistor defetive & number missing plz solve


Hello

The horizontal output transistor number for Sony KV-ES34M61

Horizontal output - [Q6807] == 2SC5480-01
Pin output - [Q6808] == 2SC5480-01 Again

Please replace bothe the transistor at the same time. Check horizontal output transformer [LOT of HOT], for any defects.. Ok

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


Hello
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 trinitron tv which turns off automatically and sporadically on average every 15 minutes


Hello
Most of the sony Tv power supplys are based on STR type regulators. Regulation of an STR is very accurate and if any overload inside the ciruit board of the TV, will be sensed by the STR and will shut off all the supply to the system itself. From your complaint we understands that there is some sort of short, not a direct short, is in your tv. Usually it may related to horizontal output transistor. At first it will work fine, but as time pass on, it will get over heated, passes more current, and place a short like circustance to the power supply rail itself, and as described above, STR will sense it and will shut down the system. After some time, say after 10 or 15 minutes, after the heat generated has gone off, the TV will again switch on, and the cycle will be repeated. You just call a technican and keep this in mind, and ask him to repair the same.

Tv was dead no vvidei no sound after checking found that power supply capacitor and horizontal deflection output transistor was defective i lost that tr no part no please tell me what should i do?


Hello
There are few models of Sony telivisions which uses transistors in vertical output section. It will be a matched pair of PNP and NPN transistors. According to Sony schematic which I have with me used 2SB6494(PNP) AND 2SD669A(NPN) as vertical outputs and 2SC2383 as vertical drive, 2SC1364 as vertical oscillator. Just try to get the orginal numbers or find its equivalents from data book. Ok.

I have a sony kv-36hs20 that will not turn on it just clicks and the power lite flashes about three different codes i think thats what that means i worked in a tv shop yrs back and have a little experence


hello!since you have an experience in repair,try to have a voltage data on the circuits of your tv..check whether there is a supply output from the plyback secondary,does the heater of the picture tube is lit?if yes your plyback is working fine,,if not,check the horizontal output transistor for any leak,open or shorted.do it same to the regulator.if these two transistor is bad replace them..check also for any leak capacitors on your horizontal section.there might be a problem in there..same with the capacitors on the power supply section.If The plyback transformer is not switching replace the jungle ic.this ic generates the horizontal pulse to the plyback..good luck hope i helped you..

please rate my help.

Sony Trinitron 29inch Color TV


The 2 blinks are an indication of over-current. This is usually because of a shorted component. The most common is the horizontal output transistor. This will be a 3-legged part attached to a heat sink close to the flyback transformer (part with red wire coming out the top). This transistor will be marked C4856 or something similar. Update this with the exact marking and I'll provide you with the full part number and approximate cost.

1996 Sony 32" Trinitron - Suddenly lost picture and sound


The most common problem with TV was the failure of the Horizontal Output Transistor, this will also damage 2 transistors in the power supply and a resistor in the power supply also. (From memory): Horizontal Output location # Q501, 2 power supply transistors Locations Q601, Q602, and resistor Location R607. Also solder the Horizontal drive transformer, you can find it by following the circuit board from the base of the Horizontal output. Some models used an IC instead of the 2 transistors in the powersupply, it will have six legs and check like 2 transistors. Good Luck.
