Question about Sanyo DS27510 27" TV

1 Answer

T.v. was hit by lightning and wont turn on

The collector voltage on the high output transistor is only 57 volts, it doesnt seem to have high enough voltage to come on.

One of my outputs does not work at all, the other works fine, when i go to bridge it doesnt word even not. How can i find out what issue i must repair, can it be the Si-PNP 250v 16a 250w


hi,
First of all you have to check The positive and negative 95V in the collector pin of all output tansistors. There should be +95V in the all collectors of MJ15024 and --95V in all collectors of MJ15025 poer the output transistors of faulty channel.ANd tere should be +/-- 0.5 volt in all output transistors base pin. All emitter pin should be aproximatly 0V. If not then you have to check the tansistors Q13 to Q16 and Q17 to Q20. Also the driver transistors Q9, Q10, Q11,Q12,.
If you need the schematic diagram that i will sent it to you.
ok

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.

how is the 200 volt supply to the video output transistors??
measure the collector voltage of the video output transistors with the crt board on and off the crt. if voltage goes up when crt board is off then crt shorted

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.

The problem you have lies either in the CRT or the CRT card. If you are familiar with the term Video B+, check this voltage at the collectors of each of the output transistors on the CRT card. You should read about 175 volts or so at each collector. You will probably find that the voltage on the collector for the GREEN output transistor is low. If so, pull the CRT card off the CRT (with the set off to prevent any arcing) and double check that collector voltage again. If it is back to normal, then you can suspect that there is a short of some kind with the GREEN gun in the CRT.
