Question about Mitsubishi Televison & Video

1 Answer

I have a Mitsubishi CS-40509 TV. It is over 12 years old. Recently, there is at least a 30 second delay before the tv responds to the remote control/control panel commands. If i turn it on, the green light doesn't light up right away and about half a minute later, it turns on. When I turn it off, the picture goes off but the green light stays lit for 30 secs then goes out. Whenever I press the input button, it does not change right away, if at all. This has never happened during all the years we had the tv. Any ideas on what this problem is and how to fix it? The picture and audio are fine.

After 4 or 5 yrs EHT ( transformer that supplies voltage to CRT TUBE - TV TUBE ) becomes weak - then few TVs ( not all TVs ) behaves exactly as you have described.............. .......so solution is EHT ( also called as flyback transformer ) should be replaced....... {{ few details about EHT---- its size will be around 3inch X 2inch X 2inch ---it will have 2 or 3 knobs to adjust focus , brightness ------ at bottom around 10 pins will be there ------- from EHT 1 thick red colour cable goes to CRT TUBE --------- on EHT its part number will be there }} -------- so if user is a technical person having idea about components ( resistors, transistors, diodes, etc ) , having tools like multimeter ( to check components) , soldering iron, soldering lead, flux, desoldering wig ( for removing components), etc also little experience in servicing field( compulsory) ----------------- then user can remove EHT from main board ---- take to electronic shop ----- buy same type EHT --------- fix to mainboard ( knobs on EHT should be adjusted according to picture --- after switching TV --- this adjustment is very important ) ----------iam from bangalore (09986222774, sathyavijayasarathibabu@ymail.com) ----- here EHT's price will be around Rs 250 ( US $ 6 ) & for my customers (in bangalore) i will take another Rs 500 (US $ 11) as service charge......i don't have any idea about EHT ' s price & service charge in your place.........since it is very risky job i suggest to contact TV service engineer ------- because they are highly experienced & can fix this component very easily. ------------ [[ sometimes along with EHT another component called transistor ( big in size - situated close to EHT - it will have 3pins - its size will be 1inch X 1/2 inch X 1/2 cm --approximately ---- black in colour ----- fixed to aluminium metal ) --- will also gets deffective --- so this component also should be checked ]] ---- in your case this transistor is good ... because when this component gets deffective then TV won't get '' ON '' .............so in your case only EHT should be replaced.........100% it works normally ----- though it is 12yrs old itseems TV TUBE is still in good condition because you have said that when display comes picture is clear......so if EHT ( same type) is replaced then your TV will work atleast for 2 more years.....GUARANTEE.......

Mitsubishi CS40509


Opeen the back panel of the tv,
near the coil you would see 6 potentometeres, (small turnng things) one is written vhold and and the other horizontal scroll, adjust these to set the picture,, Be careful nt to eletricute your self..

IF THAT FAILS THE PICTURE GETTING WIDER AND SMALLER CAN BE CAUSED BY EIGHTER THE COIL, HORISONTAL CIRCUIT OR VERTICAL CERCUIT.. most often its just a capicator.

Cs-36509 mitsubishi tv has a flicker.Makes it hard to read words. Is real bad when you first turn the tv on, but after a minute it settles down, but is still there all the time... any suggestions?


Yes first it may just be bad solder on the
flyback transformer , or the Picture in Picture
module has some bad caps . a fair shop
price is about 180-200 and it worth the repair
they are great TVs and are made to last.

ps i have repaired my mitsubishi once , and
its going strong. 18 years old .

THE OLD STUFF IS BETTER THEN THE NEW STUFF.
