Question about Sanyo DS27510 27" TV

Question about the voltages.

I tested the voltage with the collector of the high output transistor disconnected, I have 161 volts from ground to the center lead of the voltage regulator, and 57 volts to collector of the H.O.T, with respect to ground, whether power is on or off.

I have read your two previous questions on this TV. I am not sure what your original problem was. Is the High Output Transistor the same as the Line Output Transistor? 161 volts sounds correct for USA. Is the HOT Emitter/Base at ground potential, if so then you do not have a dud line output transistor, otherwise it would not sustain 57 volts.

If the voltage in h out is 200v is good or bad and the voltage regular is heat?

You mean the collector voltage on the Horz output transistor is 200 volts?

I would check this by removing the transistor and then measuring the voltage on the board (where the collector or center leg of the transistor is soldered to).

I don't know what kind of tv this is but you should see 130v or 135 volts.
RCA sets you should see 140v. If the voltage is too high replace the voltage regulator.

No picture with sound

no high voltage. most problem is possible shorted horizontal output transistor. check collector of transistor. should be 135 volts dc. if not.... power supply or fuse.

Rear projection mitsubishi vs5042 no high voltage

Are you talking about the LV power supply or the HV power supply? The terminology your using is related to the horiz drive circuit. Have you checked the B+ off the regulator which should be about 120v or, it will on the pc bd for the correct voltage. Do you have sound? If you do then you will have to use use your scope to see if you have proper drive at the base of the Horizontal Output Transistor. Then we can go from there. Oh, by the way I can tell by the voltage readings you stated both of those transistors of turned off.

I have a dell inspiron 9300 with win xp pro for an os, my lcd screen is broke, so i took it off completly. now i am trying to hook up an benq fp567s monitor through the vga output. it will get me as far as...

many people have noted two primary failures with this monitor. i have a couple time-saving troubleshooting tips, which actually apply to mostly all electronic devices. first, of course, bulging electrolytics [capacitors] should be considered suspect. i personally usually replace all the filter [power supply] caps as a matter of practice, since they are the 'hardest worked' component. anyway, a good way to test then [if you dont't have a capacitor tester capable of testing them at working voltage] is to check the voltage across the cap terminals, with your meter set to the A.C. volt scale. it should read close to zero, with only perhaps a few millivolts max. this test is only valid for the filter caps, many smaller caps are bypass or coupling caps, and you will get a reading. secondly, the transistors- many references have been made to shorted transistors in the inverter circuit. it has been stated that the transistors must be removed to test them. in almost all cases, they can be tested in circuit- first, if you're lucky enough to have an old analog vo. [such as the simpson 360, or tripplett 630] you can usually get an accurate test using the rx10 or rx100 scale. it is always possible to get an inaccurate reading depending on how it is configured in the circuit. - but a very good, accurate test is to measure the voltage between the emitter and base [while the unit is powered on, of course] you should get aproxomitately
.7 [seven tenths] of a volt if the transistor is on and conducting. this test applies to almost all electronics. the only variatin in this rule is if the transistor is a germanium type [you won't see them unless the device is from the late 1950's to mid 1960's] in which case the voltage reading will be more like 1.2 volts. also, in some cases, darlinton [multiple transistors in one case] occasionally behave differently, but you should still get a reading close to .7. on most inverter boards, the transistors are a TO-22 case. with the outer leads being the emitter and base, and the center lead the collector. in many devices, you may actually see the center [collector] lead cut, appearing to have no connection. this is because they are using the actual mounting tab, which connects to the collector, to make the connection. you should see the B+ [power supply voltage,] present at the collector to ground. i hope the readers find thid info helpful, and remember, these test procedures work for pretty much all electronics. - and one other thing- when testing capacitors, if you have an oscilloscope, you can take the reading across the cap terminals, and you should see a virtually flat line- if the cap is bad, you'll see a sawtooth pattern. one word of caution- if you use a scope, use a three-prong adapter on the ac plug of the scope, and defeat [don't connect] the earth ground of the scope. this is because many of the power supplies used have the common [ground] above earth ground potential, and you can actually damage it when you connect the ground lead of the scope-i've had it happen- especially in a few of the older sony tv's!

Television not working

Hello mo4uc,

Check to see if the Horizontal Output Transistors (HOT) collector lead is shorted to ground, this can be done by taking an ohmmeter reading between the collector and ground. If the transistor is shorted, that could be one of your problems, the other problem could be a defective IHVT (Integrated High Voltage Transformer). You will need to do a ring test to see if the IHVT is good.

I hope this helps

Thank you,

Tv repair

you can try to check if the problem is near flyback transformer
you ha to disconnect the power cord , open tv and locate power
transistor for generate high voltage it is near the big four connector 
cable the transistore you have to dissolder from board and check
with multimeter if it is shorted or not in this way base to collector
junction about 500 or more base emitter the same  collector to emittor open - delfo

Clicking sound, wont turn on

If the output transistor is good you need to measure the voltage at the collector to see if it has the needed voltage to operate,is also important to check the conections in the horizontal driver transformer and also measure the volts at the collector of the horizontal driver transistor,before you check any voltages check for loose conections and overheated areas,after everything is nice and solid then you can check for volts,be careful while measuring voltages and try not to touch anything with your bare hands while the set is on.Let us know how it goes or if you need more information.

T.V. wont turn on

The voltage might be low because is being loaded down,open the collector of the output transistor and measure the voltage again,if it goes up to 130 or the voltage is suppose to have you might be looking at a bad output transformer(flyback)there are other parts that can cause the loaded down voltage,the yoke can be one and capacitors in the deflection circuit,check to see if one of this caps is overheated (bubble)or cook,Be carefull if you open the collector when you measure the voltage,If you can try measuring the voltage somewhere else.Lets Us know if you need meore help.
