HI Bernard,

Yes, those low quality caps could have problem. It will blow the first time you turn on the set.

Hi Jestine,

Talking about capacitors, my nephew told me that some capacitors from China doesn't have the right uf readings. 2 new capacitors was blown up. After checking through the fault is with the capacitor written on it is 470uf , but actually testing with ESR it's readings is 900uf ++. So it's better to check first with ESR before fixing it up ( All new capacitors )The capacitor is dark brown color type.

HI Clinton,

If it still have problem then you may need to replace the lens/or the assembly. In your case, when you said only the buttons working normally then most probably the mainboard have problem that had caused the error. Mainboard problem is one of the hardest to detect due to lack of parts availability and repair information in the internet.

Your suggestions on DVD repair is very helpful. However, I have a DVD in my shop that is still giving the same error- no disc dispite the fact that all the above mention problems are sorted out. There is an additional problem though- only the STOP/EJECT key gives response. Can you suggest what is the possible cause?
