Post by Deantyne on Sun Mar 31, 2013 4:50 pm

pa help po sa panasonic tv:

MODEL: TC-20P1N
trouble : NO B+

STAND BY POWER ONLY,
NO CLICK, NO REACTION ON RELAY WHEN SWITCH TO POWER ON

DONE:

relay no clicking: with 24volts on coil side (RL801)
No Collector voltage on HOT D2499 (Q566)

w/ collector voltage on Q801-C5253 (main power xsistor) around 300v ,no voltage on B/E

No voltage on D892 - RM25 (R2M) B+
C808- NO VOLTAGE B+ (220UF/200VDC)

baka po may magandang loob na mag-share ng mapa nito? litong-lito na kasi ako.

Maraming Salamat Cool

focus po muna sis sa power supply, baka may open na resistor.... mostly in kiloohms value. seems to be problematic pa ang psu mo.

up...

check ko lahat ng resistor sa power supply section but no luck, no one found defective.

trannies malapit sa relay ok rin..

nang-i temporary short ko yong relay, gumana na ang power supply. baka kaya may tama na ang system ic nito?

ito ang system ic = MN1873265T8K
JUNGLE IC= AN5192NK

baka meron kayong exact pinning ng system ic? or exact mapa..

maraming salamat po ulit..

Sis, matanong ko lang.. pinalitan ko ng MN1873265TD0 umandar na, pero vertical one line ang raster.. replaced already vertical ic and suyod lahat ng peripherals pero ganon pa rin.. posible bang di sila match? kasi itong pinalit ko, bunot lang din sa ibang board, di rin sure nagpahiram sa akin if totally good ito..
